How we researched this guide
We compared six accessories chosen for the three-row Grand Cherokee L only — two full three-row liner sets, a cargo-and-backrest set, two cargo trays and a set of side steps — against maker documents from 3W, OEDRO, Rongtaod, WeatherTech, Mopar and Snailfly. Every fitment names the L, its model years and its 6- or 7-seat layout, because Grand Cherokee L part numbers split on all three, and 2-row WL or older WK2 fitment was never used as evidence for an L pick.
For ownership, we reviewed Grand Cherokee L owner and roundup coverage — mat and running-board roundups and maker fitment guides in our sources — paraphrased and linked in each review. We do not test accessories and print no prices. Four picks are sold on Amazon in a verified Grand Cherokee L fitment; where a pick is not, the review says so and puts a labelled alternative button under it. Browse the range in our off-road vehicle parts archive and the cross-vehicle guide to the best off-road bumpers.
The 30-second answer
For most Grand Cherokee L owners the 3W Floor Mats and Cargo Liner Set is the first buy: all three rows and the trunk protected in one scanned TPE set. The OEDRO Gen 2 Set covers the same ground as the value pick. Cargo-first families should look at the Rongtaod Cargo Mat with Backrest Mats, tray purists at the WeatherTech Cargo Liner Behind 3rd Row or the Mopar Molded Cargo Tray, and anyone lifting kids into row two at the Snailfly Running Boards. If your L also works off-road, start with our Jeep winch guide.
Top Pick: Best Full 3-Row Liner Set for Grand Cherokee L
3W Floor Mats and Cargo Liner Set
Best if your Grand Cherokee L carries family in all three rows: laser-scanned TPE liners for rows one to three plus a trunk mat, in the 6-passenger, no-centre-console fitment. The set 3W built for the long cabin, not a stretched 2-row kit.
Best Value Full Set with Cargo Liner for Grand Cherokee L
OEDRO Gen 2 Floor Mats and Cargo Liner Set
Best if you want the same three-row-plus-cargo coverage for less fuss: TPE liners for all three rows and a cargo liner in one 12 lb box, limited lifetime warranty, again in the 6-seat, no-centre-console L fitment.
Best Cargo and Seatback Protection for Grand Cherokee L
Rongtaod Cargo Mat with Backrest Mats
Best if the third row folds as often as it carries people: a TPE cargo mat for the well behind the third row plus backrest mats that turn the folded seatbacks into a protected loading floor.
Best Rigid Cargo Tray Behind the 3rd Row
WeatherTech Cargo Liner Behind 3rd Row
Best if only the cargo well needs armour: a rigid, raised-lip TPO tray computer-designed for the space behind the L’s third row, with an optional snap-on bumper protector. Sold direct and through dealers (see its review).
WeatherTech sells this liner direct and through dealers; no Amazon listing for the behind-3rd-row L fitment (part family 411479) could be verified. The closest Amazon-sold cargo pick here is the Rongtaod set below.
Best Factory Cargo Tray for Grand Cherokee L
Mopar Molded Cargo Tray 82216646AA
Best if you want the factory part: Mopar’s moulded tray made for the Grand Cherokee L cargo area, black with the Jeep logo, from the dealer channel. The L part number is 82216646AA — the 2-row tray is a different part.
Mopar sells this tray through dealers; no Amazon listing for part 82216646AA could be verified. The closest Amazon-sold full liner set here is the 3W set below.
Best Side Steps for Grand Cherokee L Families
Snailfly Running Boards
Best if kids and grandparents climb into a tall L daily: 4.13 in aluminium side steps made for the 2021+ Grand Cherokee L 3-row, vehicle-specific fit, with brackets and fitting tools in the box.

|---|---|---|---|---|---|---|

Alternative buttons in this table match the reviews: the WeatherTech row points at the Rongtaod cargo set and the Mopar row at the 3W full set — those two picks are dealer-channel parts with no verified Amazon listing in their Grand Cherokee L fitment. Every other button is that product’s own verified listing.
Grand Cherokee L accessory finder
Tell us your seating layout and your main need. Every result points at one of the six accessories in this guide — and because Grand Cherokee L listings split on seating, the button shows the listing we verified; confirm your seat count and centre console on it before ordering.
How to choose accessories for your Grand Cherokee L
L fitment first: the 2-row WL and WK2 are different vehicles
The L is 204.9 in long on a 121.7 in wheelbase; the 2-row WL is 193.5 in, and the WK2 shares nothing inside. Floor pans, cargo wells and rocker lengths all differ. A listing without the L, or naming the WK, is not evidence of an L fit — every pick here was verified on a source naming the L.
Six seats or seven: captain’s chairs versus the bench
Most L buyers have captain’s chairs (6 seats); the bench makes 7. Liner sets split on exactly this, and again on the optional centre console: both full sets here are the 6-passenger, no-console fitment. Count seats and check for a console before ordering any cabin liner.
Cargo behind the third row is a well, not a hold
With all rows up you have 17.2 cu ft — sedan-trunk space in an upright well. That shape decides the cargo picks: a behind-3rd-row tray protects the daily well, while a behind-2nd-row liner fits only the 46.9 cu ft folded layout. The two WeatherTech sizes are different parts; order for how you run the truck.
Folded-row hauling needs seatback protection
Fold the third row and the seatbacks become your load floor toward 84.6 cu ft maximum. Upholstery scuffs fast under totes and pet crates. That is why one pick here is a cargo mat plus backrest mats: protect the surface cargo actually slides on.
Entry height is a family feature, not a styling one
At 71.5 in tall, the L asks kids and older passengers to climb. A 4.13 in step shortens that climb on every school run, and aluminium keeps it light. Check splash-guard compatibility first, and remember steps are for feet — not rock sliders, with no such rating here.
Factory part numbers beat marketplace titles
Mopar prints separate numbers for the L and the 2-row car on the same brochure page — the moulded cargo tray is 82216646AA for the L and a different number for its sibling. Dealer-channel picks reward that discipline: quote the L number, and treat any listing that cannot state its part number as unverified.
Grand Cherokee L dimensions and cargo data
| Grand Cherokee L (WL, 3-row) | Figure | Accessory note | Source |
|---|---|---|---|
| Cargo behind 3rd row | 17.2 cu ft | The daily well: behind-3rd-row trays and the Rongtaod cargo mat are sized for this space | Jeep specifications via CarsDirect; dealer interior data |
| Cargo behind 2nd row (3rd folded) | 46.9 cu ft | The folded-row layout: seatback mats protect the loading surface; behind-2nd-row liners are separate parts | Jeep specifications via CarsDirect; dealer interior data |
| Maximum cargo (both rear rows folded) | 84.6 cu ft | Road-trip and hauling mode: full-length protection matters more than the well tray here | Jeep specifications via CarsDirect |
| Overall length / wheelbase | 204.9 in / 121.7 in | The extra length over the 2-row WL (193.5 in) is why L liners, trays and steps are L-only parts | Jeep specifications via CarsDirect |
| Seating | 6 (captain’s chairs) or 7 (bench) | Liner sets split on seat count and on the 2nd-row centre console — verify before ordering | Jeep specifications via CarsDirect |
| Legroom, 1st / 2nd / 3rd row | 41.3 / 39.4 / 30.3 in | A genuinely usable third row is why three-row liner coverage, not two, is the L standard | Dealer interior data (Claremont CDJR) |
| Maximum towing (properly equipped) | 6,200 lb | Context for trip builds: interior protection first, then the roof and hitch gear in Related guides | Jeep specifications via CarsDirect |
Keep those cargo figures in front of you while shopping: most wrong orders on this vehicle are a 2-row part bought for an L, or a behind-2nd-row liner bought for a well that measures 17.2 cu ft. The same L appears in our wider range in the off-road vehicle parts archive.
Best Grand Cherokee L accessories by budget
| Tier | What you get | Example pick from this guide |
|---|---|---|
| Single-job cargo | Cargo well and seatback protection only, nothing for the footwells | Rongtaod Cargo Mat with Backrest Mats |
| Value full set | All three rows plus a cargo liner in one TPE set | OEDRO Gen 2 Floor Mats and Cargo Liner Set |
| Premium full set | Scanned Thorex TPE, trunk mat, seatback variant available from the maker | 3W Floor Mats and Cargo Liner Set |
| Dealer tray | Rigid raised-lip tray, or the factory moulded tray, ordered by part number | WeatherTech Cargo Liner Behind 3rd Row / Mopar Molded Cargo Tray |
| Entry and access | Aluminium side steps for the daily climb into rows one and two | Snailfly Running Boards |
Money follows coverage. A cargo-only set protects the space that gets dirty first; a full set costs more because it moulds seven footwells, not one well. Dealer trays price like factory parts because they are sold like them. None of the tiers buys a different fit — each pick here is verified for the L.
Grand Cherokee L accessory types compared
| Type | What it covers | Pros | Cons | Best for |
|---|---|---|---|---|
| Full 3-row liner set | Every footwell plus the trunk or cargo area | One purchase protects the whole cabin; scanned fit; raised walls contain spills | Splits hard on seat count and console; the wrong variant will not sit flat | Families using all three rows (3W, OEDRO Gen 2) |
| Cargo mat + backrest mats | The cargo well and the folded seatbacks | Protects the hauling surface other sets ignore; seat-count independent | No footwell protection at all | Folded-row hauling (Rongtaod) |
| Rigid cargo tray | The well behind the 3rd row (or behind the 2nd, a different part) | Raised lip contains leaks; textured surface slows sliding cargo | One layout only; dealer ordering takes longer | Daily cargo-well use (WeatherTech, Mopar) |
| Side steps | The rocker panels, as a step | Shortens the climb for kids and older passengers; light in aluminium | Not rock protection; splash-guard conflicts on some fitments | Family entry duty (Snailfly) |
| Roof cross bars | The roof rails, for boxes, bikes and boats | Moves cargo out of the 17.2 cu ft well entirely | No L-variant bar had a verified Amazon listing in our research — buy by part number | Road trips; see our roof guides in Related guides |
Detailed reviews of the best Grand Cherokee L accessories
Each review follows the same order — why it earns its award, maker specs, fit and best use, pros and watch-outs, paraphrased owner reports, who should skip it, and what to pair it with. Each button names the Grand Cherokee L fitment we verified, and each alternative button is labelled as one.
Top Pick: 3W Floor Mats and Cargo Liner Set
Top Pick: Best Full 3-Row Liner Set for Grand Cherokee L
Why the 3W Floor Mats and Cargo Liner Set is our pick
The 3W set answers the L’s family problem completely: seven footwells and a cargo area shedding mud, meltwater and spilled drinks onto washable TPE instead of carpet. Scanned and injection-moulded for this cabin, its raised walls follow the long floor — third row included.
3W Floor Mats and Cargo Liner Set key specs
- Type: full liner set, 1st, 2nd and 3rd rows plus trunk mat
- Material: TPE (Thorex), injection-moulded, recyclable per maker
- Fitment: Grand Cherokee L 2021-2026, 6-passenger, without centre console
- Design: custom scan of the L cabin; raised containment walls
- Backing: air pockets on the liner backs for noise absorption (maker copy)
- Climate behaviour: maker states no odor in extreme heat, resilient in extreme cold
- Cleaning: rinse or wipe clean in minutes
- Colour: black
- Variants on the maker store: trunk mat alone, trunk mat plus seat back protector
- 7-seat note: a separate 7-seat L set exists on the maker store — this ASIN is 6-passenger only
- Warranty: lifetime (maker store)
3W Floor Mats and Cargo Liner Set: fits and best for
The verified listing fits Grand Cherokee L trucks from 2021 to 2026 with six seats — captain’s chairs, no centre console. Bench-seat owners need the separate 7-seat version from the maker’s store. It suits families using all three rows daily who want one purchase to protect all of them.
3W Floor Mats and Cargo Liner Set pros and watch-outs
Pros
- True three-row coverage, third row included, not an afterthought
- Trunk mat included, so the cargo well is protected from day one
- Raised walls contain the spills that happen in rows two and three
- Flexible TPE stays flat in cold weather instead of curling
- Seat back protector variant exists for folded-row hauling
Watch-outs
- 6-passenger, no-console fitment only on this listing
- Bench-seat owners must order the different 7-seat set
- Raised walls mean a higher lift-over when sliding bulky cargo across the trunk mat
- Black only in this set
3W Floor Mats and Cargo Liner Set: what owners report
Roundups of L mats put this bundle first for coverage, crediting the seatback protectors most sets skip: folded, the seatbacks become the loading surface, already covered (MyDriveCar Grand Cherokee mat roundup).
The same reporting stresses TPE staying flat in freezing weather, no strong smell in summer heat, and a five-minute hose-down reset (MyDriveCar Grand Cherokee mat roundup).
3W Floor Mats and Cargo Liner Set: who should not buy
Skip it if your L has the 2nd-row bench or the centre console and you are not prepared to order the matching variant — the 6-passenger set will not sit correctly around either. Console owners can start with the Rongtaod cargo set below, which does not depend on the console.
3W Floor Mats and Cargo Liner Set: pair it with
Pair it with the Rongtaod backrest mats below for folded-row cargo — either way, protect the seatbacks. For gear that rides above, see our rooftop cargo box guide.
We may earn a commission at no cost to you. Verified fitment: Grand Cherokee L 2021-2026, 6-passenger without centre console, rows 1-3 plus trunk mat. The 7-seat set is a separate maker-store product.
Tip: remove every factory carpet mat before fitting — liners stacked over carpet mats ride high at the pedals and never seat on their retention points. More upkeep habits are in our maintenance checklist.
Best Value Full Set with Cargo Liner: OEDRO Gen 2 Floor Mats and Cargo Liner Set
Best Value Full Set with Cargo Liner for Grand Cherokee L
Why the OEDRO Gen 2 Floor Mats and Cargo Liner Set is our pick
The OEDRO Gen 2 set covers the same L ground as the top pick — all three rows plus cargo — in one lighter box, with a limited lifetime warranty. It is the honest value route to a fully lined L.
OEDRO Gen 2 Floor Mats and Cargo Liner Set key specs
- Type: full liner set, 1st, 2nd and 3rd rows plus cargo liner
- Material: Thermoplastic Elastomer (TPE)
- Fitment: Grand Cherokee L 2021-2025, 6-seat, without centre console
- Fit type: vehicle specific fit (listing data)
- Included components: floor mats for 1st, 2nd and 3rd row; cargo liner
- Manufacturer part number: MAOEDptlRZ
- UPC: 199449396222 (listing data)
- Item weight: 12 lb for the set
- Colour: black
- Warranty: limited lifetime (listing data)
OEDRO Gen 2 Floor Mats and Cargo Liner Set: fits and best for
The verified listing fits Grand Cherokee L trucks from 2021 to 2025 in the 6-seat layout without a centre console. It suits owners who want full-cabin and cargo coverage in one order and hose out liners rather than detailing them. Bench and console trucks are not this fitment.
OEDRO Gen 2 Floor Mats and Cargo Liner Set pros and watch-outs
Pros
- Three rows and the cargo liner in a single purchase
- Light set at 12 lb — easy to pull out for a hose-down
- Limited lifetime warranty stated in the listing data
- Vehicle-specific moulding, not a trim-to-fit universal
- Cargo liner included rather than sold as the upsell
Watch-outs
- Same 6-seat, no-console limit as every full set here
- Owner coverage for this exact Gen 2 L set is still thin (see owners)
- No seatback protectors in this set — add them separately for folded hauling
- Fitment years end at 2025 on the listing; 2026 owners should confirm before ordering
OEDRO Gen 2 Floor Mats and Cargo Liner Set: what owners report
Owner coverage for this exact Gen 2 L set was thin in the sources reviewed, so we say so plainly: the verified record is its listing data — fitment, components, warranty (MyDriveCar Grand Cherokee mat roundup).
Wider L reporting makes the point this set depends on: L mats do not fit the 2-row car, or vice versa — the L cabin is longer, with a different floor (MyDriveCar Grand Cherokee mat roundup).
OEDRO Gen 2 Floor Mats and Cargo Liner Set: who should not buy
Skip it if your L is a 7-seat bench or wears the centre console — this set is moulded for neither. Skip it too if folded-row hauling is your main use; the Rongtaod set below protects seatbacks this set leaves bare.
OEDRO Gen 2 Floor Mats and Cargo Liner Set: pair it with
Pair it with the Rongtaod backrest mats below to close the one gap in its coverage — the folded third-row seatbacks. Keep a portable jump starter in the cargo well it lines, and the family kit is complete.
We may earn a commission at no cost to you. Verified fitment: Grand Cherokee L 2021-2025, 6-seat without centre console; part MAOEDptlRZ. The button is this set’s own verified listing.
Tip: let new TPE liners warm flat indoors before fitting; a set fitted cold and curled will fight its retention points for a week.
Best Cargo and Seatback Protection: Rongtaod Cargo Mat with Backrest Mats
Best Cargo and Seatback Protection for Grand Cherokee L
Why the Rongtaod Cargo Mat with Backrest Mats is our pick
The Rongtaod set protects the two surfaces L owners actually abuse: the 17.2 cu ft well, where groceries and sports kit live daily, and the third-row seatbacks, which become the load floor when the row folds. It is this guide’s cargo specialist.
Rongtaod Cargo Mat with Backrest Mats key specs
- Type: cargo mat plus backrest mats set
- Material: TPE (listing title)
- Fitment: Grand Cherokee L 2021-2025
- Coverage: trunk (cargo) mat for the cargo area; backrest mats for the seatbacks
- Brand / manufacturer: Rongtaod
- Model: Jeep Grand Cherokee L Cargo Liner (listing data)
- Manufacturer part number: 750250609309
- Item weight: 5.81 lb
- Product dimensions: 24.02 x 1.38 x 21.66 in (as listed)
- Seat-count note: cargo-area fitment — does not split on 6- vs 7-seat layouts the way floor liners do
- Warranty: not published in the listing data reviewed
Rongtaod Cargo Mat with Backrest Mats: fits and best for
The verified listing fits Grand Cherokee L trucks from 2021 to 2025, and living in the cargo area, it serves both seating layouts. It suits owners whose third row folds weekly — school runs up, hardware runs down.
Rongtaod Cargo Mat with Backrest Mats pros and watch-outs
Pros
- Protects the folded seatbacks other cargo mats ignore
- Cargo-well coverage without buying a full cabin set
- Works for both L seating layouts
- Light at 5.81 lb — lifts out for cleaning in seconds
- TPE wipes and rinses clean after muddy kit
Watch-outs
- No footwell protection — pair it with a liner set for full coverage
- Warranty not published in the listing data
- Backrest mats protect the third-row backs; 2nd-row backs are not the set’s stated coverage
- Owner coverage is still growing for this set (see owners)
Rongtaod Cargo Mat with Backrest Mats: what owners report
Coverage of L cargo protection singles out seatback coverage as the piece most sets miss, because folded seatbacks become the loading surface on road trips (MyDriveCar Grand Cherokee mat roundup).
Maker fitment guides for the L make the matching point: the longer cabin needs cargo options aligned with the long load floor for a tight edge seal (Lasfit Grand Cherokee liner series guide).
Rongtaod Cargo Mat with Backrest Mats: who should not buy
Skip it if your real problem is muddy footwells — this set never goes near them. The full liner sets above are the cabin answer; this is the cargo answer.
Rongtaod Cargo Mat with Backrest Mats: pair it with
Pair it with the 3W full set above for end-to-end protection: footwells, trunk and seatbacks in two purchases. Tie the load down over both with the cargo-net discipline in Safety essentials.
We may earn a commission at no cost to you. Verified fitment: Grand Cherokee L 2021-2025, cargo mat plus backrest mats, part 750250609309. The button is this set’s own verified listing.
Tip: fit the backrest mats before the first folded-row load, not after the first scuff — seatback upholstery marks permanently under sliding totes.
Best Rigid Cargo Tray Behind the 3rd Row: WeatherTech Cargo Liner Behind 3rd Row
Best Rigid Cargo Tray Behind the 3rd Row
Why the WeatherTech Cargo Liner Behind 3rd Row is our pick
WeatherTech’s behind-3rd-row liner is the rigid answer for the L’s cargo well: computer-designed for that space, a raised lip to hold spills on the tray, a textured finish that slows sliding cargo. It protects the daily 17.2 cu ft without a full liner set.
WeatherTech Cargo Liner Behind 3rd Row key specs
- Type: cargo liner (tray), behind 3rd row seating
- Material: proprietary custom-blended TPO (maker copy)
- Design: computer-designed fit for the Grand Cherokee L cargo area
- Lip: raised lip to keep spills, dirt and grease off the interior
- Surface: textured finish to help keep cargo from shifting
- Climate behaviour: remains flexible under temperature extremes (maker copy)
- Colours: black, tan, grey, cocoa
- Optional: snap-on Bumper Protector, vinyl with stainless snaps, 30×30 in or 30×40 in
- Part family: 411479 (behind 3rd row); 411480 family is the different behind-2nd-row part
- Fitment notes on listings: 2021-2022 Grand Cherokee L; shown on 2023 L Altitude X
- Warranty: not published in the copy reviewed
WeatherTech Cargo Liner Behind 3rd Row: fits and best for
Dealer listings verify this tray for the L cargo well behind the third row — the all-rows-up layout. If your third row lives folded, WeatherTech’s behind-2nd-row liner is the matching, different part. It suits owners wanting one rigid, hoseable tray and no cabin commitment.
WeatherTech Cargo Liner Behind 3rd Row pros and watch-outs
Pros
- Rigid tray holds its shape under coolers and toolboxes
- Raised lip contains the leaks a flat mat spreads
- Four colours to match the L cabin
- Optional bumper protector guards the painted sill while loading
- Laser-measured brand discipline: the two L sizes are separate parts
Watch-outs
- Dealer ordering — no verified Amazon checkout for this fitment
- Behind-3rd-row size only protects the well, nothing forward of it
- Ordering the behind-2nd-row part by mistake is the standing trap
- Rigid trays are stiffer to pull out and store than TPE mats
WeatherTech Cargo Liner Behind 3rd Row: what owners report
Cargo-liner comparisons position WeatherTech as the premium, rigid build with a high perimeter lip — the structured option next to softer TPE mats (Lasfit cargo liner comparison).
Dealer fitment pages stress the sizing discipline this review prints: behind-3rd-row and behind-2nd-row liners are different parts for different layouts (WeatherTech L cargo liner dealer listing).
WeatherTech Cargo Liner Behind 3rd Row: who should not buy
Skip it if the third row lives folded — you need the behind-2nd-row part or the Rongtaod set above, not a well tray. Skip it too if you want seatback coverage; a tray never reaches the seatbacks.
WeatherTech Cargo Liner Behind 3rd Row: pair it with
Pair it with its own snap-on Bumper Protector (named without a button; dealer part sized to this liner) for loading over the painted sill. WeatherTech’s three-row FloorLiner HP set for the L (dealer part 441632-1-2-3IM) is the cabin-side match, also named without a button.
This liner is sold direct and through dealers rather than on a verifiable Amazon listing, so the button below is the closest cargo pick sold on Amazon in this guide. The review above is for the named product itself.
Check Price: Rongtaod Cargo Mat (Amazon alternative)
We may earn a commission at no cost to you. Fitment note: part family 411479, Grand Cherokee L, behind 3rd row seating. The button below is the labelled Amazon alternative, not this product’s listing.
Tip: order by the words behind 3rd row, not by the picture — the two L trays look alike in thumbnails and protect different layouts.
Best Factory Cargo Tray: Mopar Molded Cargo Tray 82216646AA
Best Factory Cargo Tray for Grand Cherokee L
Why the Mopar Molded Cargo Tray 82216646AA is our pick
The Mopar tray is the factory answer to the same well: a moulded tray under a Grand Cherokee L part number, full-area protection, easy to clean, black with the Jeep logo. For owners keeping their L dealer-original, no aftermarket mat substitutes for the correct number.
Mopar Molded Cargo Tray 82216646AA key specs
- Type: moulded cargo tray, factory accessory
- Maker: Mopar (Jeep Authentic Accessories)
- Part number: 82216646AA — Grand Cherokee L
- Not the L part: 82216645AA is the 2-row Grand Cherokee tray
- Coverage: full-area cargo protection (maker copy)
- Finish: black, with Jeep Brand logo
- Cleaning: easy to clean (maker copy)
- Channel: Mopar dealer network
- Brochure siblings for the L: Cargo Liner 82216020AA; Premium Carpet Cargo Mat 82216151AB; Cargo Security Cover 82216346AA
- Warranty: not published in the brochure copy reviewed
Mopar Molded Cargo Tray 82216646AA: fits and best for
Mopar’s brochure assigns this tray to the L by its own part number, distinct from the 2-row tray on the same page. It suits owners who buy at the parts counter and may add the L’s retractable Cargo Security Cover (82216346AA) from the same catalogue.
Mopar Molded Cargo Tray 82216646AA pros and watch-outs
Pros
- Factory part, made for the L cargo area by number
- Full-area protection in one moulded piece
- Jeep logo and black finish match the cabin
- Easy-clean surface for grocery and pet duty
- Sits inside a full L accessory family from the same brochure
Watch-outs
- Dealer channel only — no verified Amazon listing
- Brochure copy is brief: no published weight or warranty in the copy reviewed
- The 2-row tray number is one digit away — quote the full part number
- A tray alone leaves footwells and seatbacks unprotected
Mopar Molded Cargo Tray 82216646AA: what owners report
The record here is maker documentation rather than owner threads, said plainly: the Mopar brochure prints the tray, its L part number and its full-area, easy-clean description (Mopar Grand Cherokee accessories brochure).
The same brochure separates every L part from its 2-row sibling by number — the discipline to copy when ordering any factory accessory (Mopar Grand Cherokee accessories brochure).
Mopar Molded Cargo Tray 82216646AA: who should not buy
Skip it if you want checkout convenience or the lowest spend — the Rongtaod set above covers the well from Amazon today. Skip it if you need footwell liners too; a tray is cargo-only.
Mopar Molded Cargo Tray 82216646AA: pair it with
Pair it with the Mopar Cargo Security Cover for the L (82216346AA, named without a button; dealer part) to keep the tray’s contents out of sight, and the Mopar Envelope Cargo Net (82216437AA) to hold them still. More factory-style picks are in our Jeep accessories buying guide.
This tray is sold through the Mopar dealer channel rather than on a verifiable Amazon listing, so the button below is the closest full liner set sold on Amazon in this guide. The review above is for the named product itself.

We may earn a commission at no cost to you. Fitment note: part 82216646AA, Grand Cherokee L. The button below is the labelled Amazon alternative, not this product’s listing.
Tip: quote all of 82216646AA at the parts counter — the 2-row tray differs by a single digit and fits a different cargo area.
Best Side Steps for Grand Cherokee L Families: Snailfly Running Boards
Best Side Steps for Grand Cherokee L Families
Why the Snailfly Running Boards is our pick
A 71.5 in tall SUV makes every entry a climb, in school shoes and dress shoes, not boots. Snailfly’s aluminium boards give the L a 4.13 in step at each rocker, made for the 2021 and newer 3-row car, brackets and fitting tools in the box.
Snailfly Running Boards key specs
- Type: running boards / side steps, pair (left and right)
- Material: aluminium; exterior finish aluminium
- Step width: 4.13 in (listing title)
- Colour: black
- Fitment: Jeep Grand Cherokee L 3-row, 2021-2026 (listing title); vehicle service type: Grand Cherokee L 2021+
- Fit type: vehicle specific fit (listing data)
- Model: SN-C785GCLRB
- Manufacturer part number: SN-C785C508V02
- Item weight: 40.9 lb for the pair
- Package dimensions: 81.5 x 11.7 x 8.5 in
- In the box (manual): pair of boards, brackets, bolts, nuts, washers, rivnut tool, plastic pry tool
- Load capacity: not published in the copy reviewed
- Warranty: not published in the copy reviewed
Snailfly Running Boards: fits and best for
The verified listing fits the Grand Cherokee L 3-row from 2021 to 2026 — not the 2-row WL, whose rockers are shorter. The manual notes incompatibility with front splash guards. They suit families loading children into row two daily, and Ls carrying older passengers.
Snailfly Running Boards pros and watch-outs
Pros
- Real step width for small and older feet, not a styling ledge
- Aluminium keeps the pair to 40.9 lb and resists corrosion
- Vehicle-specific fit for the L’s longer rocker
- Fitting tools included, rivnut tool and pry tool in the box
- Black finish matches the L’s trim
Watch-outs
- Not compatible with front splash guards (manual note)
- No load capacity published — treat them as steps, never as rock sliders or jacking points
- Fitting needs mechanical aptitude per the manual; professional fitting is the fallback
- Steps collect mud and slush exactly where shoes land — hose them with the liners
Snailfly Running Boards: what owners report
Running-board roundups covering the 2021 and newer L credit aluminium boards with easier entry, brackets, hardware and instructions in the box (Top5Best Grand Cherokee running boards roundup).
Comparison coverage of L boards makes the family case: a flat, anti-slip stepping surface matters most for kids and road trips in a tall SUV (MyOffRoadGear running boards comparison).
Snailfly Running Boards: who should not buy
Skip them if your L wears front splash guards you intend to keep, or if what you actually need is rocker armour for trails — these are entry steps with no published load or impact rating. Trail-first L owners should start from our off-road winch guide instead.
Snailfly Running Boards: pair it with
Pair them with roof cross bars for the loads the steps help you reach (named without a button: the BRIGHTLINES bar made for the 2021-2023 Grand Cherokee L had no verified Amazon listing in our research). Our roof rack system guide covers the bars and boxes that fit the role.

Tip: test-fit both boards and brackets loosely before tightening anything; the manual’s sequence assumes you confirm the rocker mounts on both sides first.

Alternative buttons in this table match the reviews: the WeatherTech column points at the Rongtaod cargo set and the Mopar column at the 3W full set — those two picks have no verified Amazon listing in their Grand Cherokee L fitment. The table compares verified specifications only — fitment evidence first, then coverage, material and warranty as the makers state them.
Fitment & installation on the Grand Cherokee L
Liner sets drop in once the factory carpet mats come out: seat each liner on its retention points, work from the pedals outward, and confirm no edge rides up a seat rail before the first drive. Cargo trays and mats need nothing but a clean well — vacuum the 17.2 cu ft space first so grit does not grind under a rigid tray. Backrest mats strap or fasten to the seatbacks per their instructions; fit them with the row upright, then fold to check they stay put.
The Snailfly boards are the only bolt-on job here: brackets, bolts and a rivnut tool are in the box, the manual asks for mechanical aptitude, and front splash guards conflict. Everything else in this guide is a no-tool fit. Whichever you fit, keep the paperwork with the part numbers — on this vehicle the number is the fitment. Bigger L builds cross into the rest of this site: our Wrangler winch guide, Gladiator winch guide and running boards for SUVs guide cover the neighbouring jobs.
Safety essentials
Six rules for living with Grand Cherokee L accessories
- Never stack a liner over a carpet mat, and never drive with a driver liner unseated from its retention points — a loose mat near the pedals is a hazard, not an accessory.
- Secure everything in the cargo well: in a sudden stop, loose kit behind the third row travels forward over the seatbacks.
- Keep the third-row seatbelts and child-seat anchors clear of backrest mats and cargo — protection never covers a restraint.
- Treat side steps as steps only: no published load rating here means no standing loads, no jacking, no recovery use.
- Re-check board brackets after the first weeks and after winter salt; a loose step fails exactly when a foot trusts it.
- Mind the roof and the well together: cargo moved to a roof box still counts against the vehicle’s roof load, and the well’s 17.2 cu ft is volume, not a weight rating.
Three cargo-discipline adds that finish the job, two of them verified in this guide’s own research:
Rongtaod Cargo Mat with Backrest Mats — the well and seatback coverage that keeps secured cargo from scuffing the surfaces it rests on.
Check Price: Rongtaod Cargo Mat
OEDRO Gen 2 cargo liner (part of the full set) — the cargo end of the value set, for owners who lined the cabin and want the well to match.
Mopar Envelope Cargo Net 82216437AA — the factory net that fastens to the cargo tie-down loops to hold loose items still (named without a button; dealer part, no verified Amazon listing in our research).
Round out the kit with rated tie-down straps and a torch (named without buttons; no listing was verified for this guide) and keep the rest of the family kit organised through our Jeep accessories under 100 guide, essential winching accessories and recovery kit guide.
Troubleshooting common Grand Cherokee L accessory problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Floor liner will not sit flat in row two | Wrong layout variant — a 6-passenger set on a bench truck, or a console the set was not moulded around | Stop and re-check seat count and console against the listing before forcing it; order the matching variant |
| Cargo tray rocks or rattles in the well | Grit under a rigid tray, or the behind-2nd-row part fitted in the behind-3rd-row well | Lift it out, vacuum the well, and confirm the part matches the layout you run |
| Backrest mats slide when the row folds | Fasteners not seated, or mats fitted with the row already folded | Refit with the row upright, seat every fastener, then fold and check again |
| Running board flexes or creaks | Bracket bolts not torqued in sequence, or mounts settled after fitting | Re-torque in the manual’s sequence and re-check after the first weeks of use |
| Liner edges curl in winter | TPE fitted cold from the box, or stored rolled | Warm the liner flat indoors and refit; store liners flat, never rolled |
| Wet smell after winter use | Meltwater trapped under a liner that was never lifted out | Pull the liners, dry the carpet fully, hose the liners and refit dry |
Who should NOT buy these Grand Cherokee L accessories
2-row WL and WK2 owners. Nothing in this guide fits your car. The L’s floor, well and rockers are different parts of a longer vehicle, and the listings here name the L for a reason. Our wider off-road vehicle parts archive is the place to start instead.
Bench-seat and console owners shopping the headline listings. Both full sets here are the 6-passenger, no-console moulding. The right variant exists — 3W sells a separate 7-seat L set — but it is a different product, not a fit option on the same button.
Anyone who wants one part to protect every layout. Behind-3rd-row and behind-2nd-row cargo parts are different sizes for different shapes of the same car. Pick the layout you run daily; the other layout is a second purchase, not a compromise setting.
Trail drivers looking for rocker armour. The Snailfly boards are entry steps with no published load or impact rating. They help people climb in; they do not protect rockers on rocks, and treating them as armour will bend them.
Anyone who will not check a part number. On this vehicle the difference between fitting and not fitting is one digit in a Mopar number or one word — console — in a liner title. If that homework is not happening, order through a dealer who fits it, as readers of our truck winch guide will recognise.

FAQ
Do Grand Cherokee L accessories fit the 2-row Grand Cherokee?
No. The L is a longer vehicle (204.9 in against 193.5 in) with a third row, a different floor and a different cargo well. Liner sets, cargo trays and side steps are all L-specific parts. A listing that does not name the Grand Cherokee L is not evidence of a fit, and WK2 (2011-2021) parts fit neither WL model.
What is the cargo space behind the third row of the Grand Cherokee L?
17.2 cu ft with all rows up — roughly sedan-trunk volume in an upright well. Folding the third row opens 46.9 cu ft behind the second row, and folding both rear rows gives 84.6 cu ft maximum. Those three shapes are why cargo accessories for the L come in behind-3rd-row and behind-2nd-row sizes.
Will the 6-passenger liner sets fit my 7-seat Grand Cherokee L?
No. The 3W and OEDRO sets verified here are moulded for six seats — captain’s chairs and no centre console. The bench changes the 2nd-row floor shape. 3W sells a separate 7-seat version of its set through its own store; order that variant rather than forcing the 6-passenger moulding.
What if my Grand Cherokee L has the 2nd-row centre console?
Do not order the no-console sets blind — the console changes the 2nd-row moulding and the set will not sit correctly around it. Cargo-area accessories (the Rongtaod set, the WeatherTech tray, the Mopar tray) do not depend on the console and are the safe first purchases while you source console-fit floor liners by exact part number.
Behind 3rd row or behind 2nd row cargo liner: which do I need?
The one matching how you run the vehicle. Behind-3rd-row parts protect the 17.2 cu ft well with all seats up; behind-2nd-row parts cover the larger floor with the third row folded. WeatherTech sells both sizes for the L as different part families (411479 versus 411480), and they are not interchangeable.
Are Mopar accessories worth buying over aftermarket for the L?
They are worth it when the factory part number matters to you: the Mopar moulded tray (82216646AA) is made for the L cargo area and sits in a full L accessory family, covers and nets included. Aftermarket sets win on checkout convenience and on coverage per purchase — the full liner sets protect footwells a tray never reaches.
Do running boards fit the Grand Cherokee L if they fit the 2-row?
No — the L’s wheelbase is 121.7 in and its rockers are longer, so boards are length- and mount-specific. The Snailfly set verified here is titled and listed for the 2021-2026 Grand Cherokee L 3-row. Note its manual’s warning: not compatible with front splash guards.
How do I clean TPE liners and cargo mats?
Lift them out, shake off grit, hose or wipe them down and let them dry before refitting. That minutes-long routine is the practical advantage of TPE over carpet mats. Dry the vehicle carpet fully at the same time — meltwater trapped under a liner is what causes the wet smell owners report.
What should a new Grand Cherokee L owner buy first?
Protection for the surfaces your life touches daily. For most families that is a full three-row liner set (3W or OEDRO here) or, if cargo is the pain point, the Rongtaod cargo and backrest set. Add side steps when the climb into row two becomes the daily complaint. The finder at the top of this guide routes you by seating and need.
