How we researched this guide
We compared six swing-out bed storage boxes whose Amazon listings we could verify on October 16, 2026 — five UnderCover SwingCase fitments covering Ford, GM and Ram trucks, and one budget wheel-well box from VEVOR. For each pick we recorded the part number, the exact fitment in the listing title, the UPC and the warranty term, and cross-checked the shared platform specifications against UnderCover maker summaries and retailer spec tables. Bed-accessory context — tonneau compatibility and tailgate sealing — carries over from the verified research behind our truck bed covers guide.
For ownership, the honest position is that swing-case owner coverage is thinner and more second-hand than winch coverage: the usable material is retailer editorial digests of buyer reports, not long forum threads. We paraphrased those digests, linked them in each review, and labelled them as digests. Where a pick has almost no owner coverage, the review says so. We do not test storage boxes and we print no prices. Fitment is the whole game here: truck, generation and side of bed each change the part number.
The 30-second answer
A swing case stores recovery gear, straps and tools in the dead space over the rear wheel well and swings it out to the tailgate. Current F-150 owners start with the UnderCover SwingCase SC203P; Silverado and Sierra owners with the SC104D; Ram owners with the SC302D; Super Duty owners with the SC205D. Budget buyers look at the VEVOR Wheel Well Storage Box, and 1999–2014 F-150 owners at the SC201D. The gear that fills one is in our recovery kit guide.
Top Pick: Best Swing Case for F-150
UnderCover SwingCase SC203P
Best if you run a 2015–2025 F-150, Lightning included: the passenger-side case swings out nearly 180 degrees to the tailgate, carries a maker rating of 75 lb, locks with a key, and lifts off its hinge when the full bed is needed. This is the fitment most owners start with.
Best Swing Case for Silverado and Sierra
UnderCover SwingCase SC104D
Best if you run a 2019–2025 Silverado 1500 or Sierra 1500 on the driver side: the same SwingCase platform moulded for the GM bed. One hard limit in its listing: it does not fit Carbon Pro beds or MultiPro tailgate trucks, so check yours before ordering.
Best Swing Case for Ram 1500
UnderCover SwingCase SC302D
Best if you run a 2019–2025 Ram 1500 or 2500 in the new body style, driver side: a factory-fit case for the Ram wheel well with the platform’s tray, moisture seal and key-lockable lid. RamBox trucks need their fitment confirmed first.
Best Swing Case for Super Duty
UnderCover SwingCase SC205D
Best if your truck is a 2017–2025 F-250 or F-350 Super Duty: the driver-side case built for the bigger bed, with the same 75 lb maker rating and one-year warranty. Work trucks gain the most here, because the gear lives at the tailgate, not under a load.
Best Budget Swing-Out Box
VEVOR Wheel Well Storage Box
Best if the UnderCover price is the obstacle: an ABS wheel-well box for the Silverado driver side with a lockable lid, a password padlock and a listed 6.6 gallon volume. It gives up the UnderCover tray-and-hinge polish for a simpler build; read its watch-outs before choosing it.
Best Swing Case for Older F-150
UnderCover SwingCase SC201D
Best if your F-150 is a 1999–2014 truck that still works daily: the original-fitment driver-side case, same platform ratings, sized for the older bed. Older trucks are where a swing case earns its keep longest, because the cab storage was never generous.

Every UnderCover case here is the same platform in a different moulding: ABS case, sliding tray, moisture seal, six-screw bracket. The differences that matter are the truck, the generation and the side. The same trucks appear with covers fitted in our GMC Sierra bed cover guide and the wider truck bed covers archive.
Swing case fitment finder
Tell us your truck, which side of the bed you want, and what matters most. Every result points at one of the six boxes in this guide, with the verified listing for that fitment. If your truck is a variant a listing excludes — a Carbon Pro bed, a MultiPro tailgate on the GM part, a RamBox bed — the finder says so and routes you to the safe answer instead of the wrong part.
How to choose a truck bed swing case
Fitment first: truck, generation, side
A swing case is moulded for one wheel well on one truck generation, and the driver and passenger versions are mirror parts, not the same box flipped over. Start from your exact truck and year range, then pick the side you load from — most owners work from the driver side at the tailgate, while a passenger case suits trucks parked tight against a wall on the driver side. A case one generation off will not seat on the bracket.
Capacity honesty: 75 lb and about two cubic feet
Every UnderCover case here carries the same maker rating: 75 lb of cargo, in a case of roughly two cubic feet. That is a recovery kit, a strap set, jump leads, a tyre kit and hand tools — not a workshop. The VEVOR box lists the same 75 lb maximum with a 6.6 gallon volume. If your gear list is longer than that, the honest answer is two cases, one per side, or a different storage type entirely, covered in the types table below.
The swing and lift-off mechanism
The mechanism is the reason to buy one: pull the release, the case swings out nearly 180 degrees over the tailgate, and the gear comes to you. Latched back, it locks over the wheel well. It also lifts off the hinge without tools and stands upright on the ground, which matters at a roadside repair. Judge a case by how positively that latch engages — owner digests name latch wear as the platform’s recurring watch-out, so it is the first thing to check on delivery.
Lid, lock and weather sealing
All six boxes seal the lid against moisture and lock it with a key or, on the VEVOR, a key plus a password padlock. Treat the lock honestly: it keeps honest people out and slows everyone else, behind a tailgate, out of sight. It is not a steel safe. The moisture seal keeps road spray and dust off the contents; it does not make the case submersible, and gear that must stay bone dry still belongs in a dry bag inside the case.
Tonneau cover and bed liner compatibility
UnderCover states the SwingCase keeps about three inches of clearance and works with virtually all tonneau covers — soft, hard, folding and rolling — which is why swing cases pair so often with the covers in our pillar guide. Liners are the friction point: owner summaries describe trimming spray-in or drop-in liners at the bracket on some trucks. Check your liner at the rear wheel well before the bracket screws go in, not after.
One case or two
The platform is sold per side precisely so owners can run a pair: recovery gear on one side, work tools on the other, each within its own 75 lb rating. Two cases double the organised storage without touching the bed floor between the wheel wells, which stays free for full-width loads. Start with one, live with it for a season, and add the second only if the first is genuinely full — an empty second case is just weight and cost.

Two rows are deliberately not picks: the HD GM and Tundra fitments are real, verified listings, but this guide reviews six boxes in full rather than padding the count. If your truck is one of those two, the named listings are the verified starting point, and the choosing criteria above apply unchanged. Bed gear pairs with front gear on most builds here — see our truck winch guide and pickup truck winch guide.
Best swing cases by budget
| Tier | What you get | Example pick from this guide |
|---|---|---|
| Budget | ABS wheel-well box, lockable lid and padlock, simpler hardware | VEVOR Wheel Well Storage Box |
| Core | The UnderCover platform: tray, moisture seal, lift-off hinge, 1-year warranty | UnderCover SwingCase SC203P |
| Core, other brands of truck | Same platform moulded for GM, Ram or Super Duty beds | SC104D / SC302D / SC205D |
| Older truck value | Full platform ratings on a previous-generation fitment | UnderCover SwingCase SC201D |
| Pair (both sides) | Two cases, one per side, each rated 75 lb | Any UnderCover pick plus its sibling side part |
Money in this category buys moulding quality, the tray and hinge finish, and the maker’s support — not capacity, which is 75 lb almost everywhere you look. That is why the budget box is a legitimate pick and not a trap: it gives up polish, not the core idea.
Truck bed storage types compared
| Type | Where it sits | Pros | Cons | Best for |
|---|---|---|---|---|
| Swing case | Over the rear wheel well, swings out | Uses dead space, gear comes to the tailgate, lifts off, bed floor stays clear | About 2 cu ft and 75 lb per case; fitment-specific | Daily gear kits (all six picks here) |
| Crossover toolbox | Across the bed behind the cab | Largest single volume, steel options | Eats bed length, climbing in to reach the middle | Big tool sets on long beds |
| Side-mount box (fixed) | Along the bed side, no swing | Simple, sturdy | Reach over the side or climb in; no lift-off | Permanent trade setups |
| Drawer system | Full bed floor platform | Huge organised volume, load deck on top | Heaviest and dearest option; raises the load floor | Dedicated overland and trade builds |
| Loose bins and bags | Anywhere in the bed | Cheapest, flexible | Slides, soaks and walks away; no lock | Occasional, low-value loads |
Detailed reviews of the best truck bed swing cases
Each review follows the same order — why it earns its award, maker specs, fit and best use, pros and watch-outs, the owner coverage that exists, who should skip it, and what to pair it with. Each button names the fitment we verified.
Top Pick: UnderCover SwingCase SC203P
Top Pick: Best Swing Case for F-150
Why the UnderCover SwingCase SC203P is our pick
The SC203P is the default swing case for the best-selling truck bed in the country, and it earns the top spot on fitment breadth alone: one verified part covers 2015–2025 F-150s including the Lightning, on the passenger side most owners pair with a driver-side workflow at the tailgate. The platform underneath is the proven one — ABS case, 75 lb maker rating, sliding tray, key-lockable lid — in the moulding the most buyers need.
UnderCover SwingCase SC203P key specs
- Type: swing-out wheel-well storage box, passenger side
- Construction: high-impact ABS plastic, custom-moulded
- Capacity: rated 75 lb of cargo (maker rating)
- Storage volume: about 2 cubic feet (family listing data)
- Case weight: 16 lb
- Locking: key-lockable lid, twist handle; 2 keys in the install kit class
- Seal: perimeter moisture seal
- Interior: removable sliding organisational tray; cup holders in the lid
- Access: swings out nearly 180 degrees; lifts off the hinge without tools
- Install: bracket with six self-tapping screws; maker install sheet lists socket and Torx tools
- Verified part: SC203P; UPC 897197010604
- Warranty: 1-year manufacturer guarantee
UnderCover SwingCase SC203P: fits and best for
The verified listing fits Ford F-150 trucks, 2015 to 2025, passenger side, and names the Lightning as included. A driver-side sibling (SC203D) exists in the same line for owners who want the pair or the other side. It suits F-150 owners whose daily kit — straps, jump leads, recovery basics — currently lives loose in the bed or behind the seats.
UnderCover SwingCase SC203P pros and watch-outs
Pros
- Widest current F-150 fitment in this guide, Lightning included
- Gear swings to the tailgate; no climbing into the bed
- Lifts off in seconds for full-width loads
- Works under most tonneau covers per the maker
- Tray keeps small items off the case floor
Watch-outs
- Latch wear is the recurring digest watch-out for the line
- Loaded cases can sag past roughly 50 lb on rough roads, per digests
- Passenger side only in this verified listing
- ABS lock is a deterrent, not high security
UnderCover SwingCase SC203P: what owners report
Buyer-report digests praise the same point owners of the wider line repeat: gear reachable from the tailgate without climbing in, and an install most finish in about half an hour (retailer editorial digest of SwingCase buyer reports).
The watch-outs in those digests are consistent: the receiving latch can wear, a heavily loaded case can sag on rough roads, and some owners hold the case or lid open because it can swing back (retailer editorial digest, SC201D). Treat these as digest summaries, not forum consensus — dedicated owner threads for individual fitments are thin.
UnderCover SwingCase SC203P: who should not buy
Skip it if your gear list is bulky — two cubic feet fills fast. A drawer system or crossover box serves bulk; this case serves the daily kit.
UnderCover SwingCase SC203P: pair it with
Pair it with the recovery basics it will actually store: the snatch block and shackles in Safety essentials below, chosen from our snatch block guide and shackle guide.
We may earn a commission at no cost to you. Verified fitment: part SC203P, F-150 2015–2025 passenger side, Lightning included. Other trucks and sides use different part numbers.
Tip: load the tray with the items you grab weekly and the case floor with the heavy kit; a top-heavy case is the one that feels loose on its latch. The install sequence is in the maker sheet (UnderCover SC203P installation sheet).
Best for Silverado and Sierra: UnderCover SwingCase SC104D
Best Swing Case for Silverado and Sierra
Why the UnderCover SwingCase SC104D is our pick
GM trucks get their own moulding, and the SC104D is it for the current 1500 generation: driver side, 2019–2025 Silverado and Sierra. It earns its place by being the verified GM fitment in a line otherwise dominated by Ford parts — with one exclusion printed in its own listing title that this review repeats rather than buries: no Carbon Pro bed, no MultiPro tailgate.
UnderCover SwingCase SC104D key specs
- Type: swing-out wheel-well storage box, driver side
- Construction: high-impact ABS plastic, custom-moulded
- Capacity: rated 75 lb of cargo (maker rating)
- Locking: key-lockable lid with moisture seal
- Interior: removable sliding organisational tray; cup holders in the lid
- Access: swings out nearly 180 degrees; lifts off the hinge without tools
- Tonneau clearance: about 3 in per maker copy; fits most cover types
- Install: bracket with six self-tapping screws
- Exclusions: Carbon Pro bed and MultiPro tailgate trucks (listing title)
- Verified part: SC104D; UPC 192631021889
- Warranty: 1-year (listing warranty field)
UnderCover SwingCase SC104D: fits and best for
The verified listing fits Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, 2019 to 2025, driver side, excluding Carbon Pro beds and MultiPro tailgates. A passenger-side sibling (SC104P) is verified in the fitment table. Sierra owners comparing bed gear will find the same trucks in our Sierra bed cover guide.
UnderCover SwingCase SC104D pros and watch-outs
Pros
- The verified current-generation GM fitment
- Driver side suits tailgate-first loading
- Same tray, seal and lift-off hinge as the Top Pick
- Exclusions stated plainly in the listing itself
- Pairs with most tonneau covers per the maker
Watch-outs
- Carbon Pro and MultiPro exclusion removes two popular Sierra specs
- Listing year range has printed as 2019–2023 in some crawls; current title runs to 2025
- Same latch and sag watch-outs as the wider line
- One side per part number, like every case here
UnderCover SwingCase SC104D: what owners report
GM-specific owner coverage is thin, and we say so plainly: the usable material is the platform-level digest record — convenience praised, latch wear and loaded sag named as watch-outs (retailer editorial digest of SwingCase buyer reports).
No dedicated Sierra or Silverado swing-case thread with real depth surfaced in this research; buy on the fitment and the platform record, not on invented GM owner themes.
UnderCover SwingCase SC104D: who should not buy
Skip it outright if your Sierra has the MultiPro tailgate or the Carbon Pro bed — the listing excludes both. The VEVOR box below is the alternative to check for clearance, or order through a dealer who confirms fitment.
UnderCover SwingCase SC104D: pair it with
Pair it with a tailgate seal habit from our pillar research: a swing case keeps its own contents dry, and the bed around it still takes dust past the tailgate. Front-end pairing is in our pickup winch guide.
We may earn a commission at no cost to you. Verified fitment: part SC104D, Silverado / Sierra 1500 2019–2025 driver side, not Carbon Pro, not MultiPro. Other GM beds use different part numbers.
Tip: before ordering, photograph your tailgate badge and bed material; MultiPro and Carbon Pro are the two answers that change this part from fit to no-fit.
Best for Ram: UnderCover SwingCase SC302D
Best Swing Case for Ram 1500
Why the UnderCover SwingCase SC302D is our pick
Ram owners are usually offered Ford parts and told to make them work. The SC302D is the opposite: a case moulded for the new-body Ram wheel well, driver side, spanning the 1500 and the 2500 on the same verified part. It carries the full platform — tray, seal, lockable lid, lift-off hinge — with the Ram-specific warning this guide repeats: RamBox trucks are their own storage system and need fitment confirmed first.
UnderCover SwingCase SC302D key specs
- Type: swing-out wheel-well storage box, driver side
- Construction: high-impact ABS plastic, custom-moulded
- Capacity: rated 75 lb of cargo (maker rating)
- Locking: key-lockable lid with moisture seal
- Interior: removable sliding organisational tray; cup holders in the lid
- Access: swings out nearly 180 degrees; lifts off the hinge without tools
- Install: bracket with six self-tapping screws; hardware pack and instructions included
- Fitment note: new body style; RamBox fitment to confirm on the listing
- Verified part: SC302D; UPC 816391029069
- Warranty: 1-year (listing warranty description)
UnderCover SwingCase SC302D: fits and best for
The verified listing fits Ram 1500 and 2500 trucks, 2019 to 2025, new body style, driver side. It suits Ram owners who tow — the case is the natural home for the hitch pins, straps and breakaway kit that otherwise rattle around the bed — and anyone whose Ram does double duty as the family truck, where loose gear in the cab is not an option.
UnderCover SwingCase SC302D pros and watch-outs
Pros
- A genuine Ram moulding, not a universal box
- One part spans Ram 1500 and 2500 new-body trucks
- Full platform feature set: tray, seal, lock, lift-off
- Hardware and instructions in the box per the listing
- Keeps towing kit at the tailgate where it is used
Watch-outs
- RamBox beds need a fitment confirmation before ordering
- Driver side only in this verified listing
- Same platform watch-outs: latch wear, loaded sag
- Ram-specific owner coverage is thin (see owners section)
UnderCover SwingCase SC302D: what owners report
Ram-specific owner coverage is thin in the sources checked; the platform digest record — convenience and quick installs praised, latch and sag watch-outs named — is the honest summary (retailer editorial digest of SwingCase buyer reports).
Maker and retailer summaries for the Ram part confirm the fitment and feature set used here (retailer SwingCase feature summary); we invent no Ram owner themes beyond that.
UnderCover SwingCase SC302D: who should not buy
Skip it if your Ram has the RamBox system and the listing does not confirm your exact bed — a case that cannot seat on its bracket is a return, not a project.
UnderCover SwingCase SC302D: pair it with
Pair it with the towing kit it will store and our receiver hitch winch mount guide if the same truck pulls recovery duty at the rear.
We may earn a commission at no cost to you. Verified fitment: part SC302D, Ram 1500 / 2500 2019–2025 driver side, new body style. RamBox owners must confirm fitment on the listing.
Tip: fit the bracket, then swing the empty case through its full arc before loading it; any liner interference shows up empty, when it is still easy to trim.
Best for Super Duty: UnderCover SwingCase SC205D
Best Swing Case for Super Duty
Why the UnderCover SwingCase SC205D is our pick
Super Duty beds earn their storage the hard way: the gear is heavier, the roads to the job are worse, and the cab is already full. The SC205D puts the daily kit at the tailgate of 2017–2025 F-250 and F-350 trucks, driver side, on the same platform as the rest of the line — and the digest record for the older Super Duty fitment is exactly why its watch-outs below are written plainly.
UnderCover SwingCase SC205D key specs
- Type: swing-out wheel-well storage box, driver side
- Construction: ABS plastic (retailer attribute tables)
- Capacity: rated 75 lb of cargo (maker rating)
- Case size: upper case 29 in, lower case 15 in, width 8 in (retailer attributes)
- Locking: key-lockable lid; weather resistant per retailer attributes
- Interior: removable sliding organisational tray; cup holders in the lid
- Access: swings out nearly 180 degrees; lifts off the hinge without tools
- Install: bracket with six self-tapping screws; hardware included
- Origin: USA per retailer attribute tables
- Verified part: SC205D; UPC 897197002708
- Warranty: 12 months (retailer attribute tables; maker 1-year guarantee)
UnderCover SwingCase SC205D: fits and best for
The verified listing fits Ford F-250 and F-350 Super Duty trucks, 2017 to 2025, driver side. It suits work trucks that carry a recovery and repair kit daily — the case keeps that kit out of the cab and off the bed floor, reachable from the tailgate at the job and at the roadside alike. Heavier builds on the same trucks are in our heavy-duty truck winch guide.
UnderCover SwingCase SC205D pros and watch-outs
Pros
- Built for the bigger Super Duty bed and work use
- Tailgate access suits gloves-on, end-of-day loading
- Full platform feature set
- Long-running fitment with a deep listing record
- Lifts off when the bed has to carry sheet goods flat
Watch-outs
- Older-fitment digests name sag past roughly 50 lb and a plastic release lever as weak points
- Keep working loads honest: the rating is 75 lb, not a suggestion to exceed
- Driver side only in this verified listing
- One-year warranty is short for a work truck accessory
UnderCover SwingCase SC205D: what owners report
Digests of the older Super Duty fitment (SC200D) report simple installs and useful small-gear storage, alongside complaints about sag under heavier loads and the release lever over time (retailer editorial digest, Super Duty SwingCase). The current part shares the platform, so the review carries those watch-outs openly.
Retailer application data confirms the 2017-onwards Super Duty fitment and the ABS, lockable, weather-resistant attribute set (retailer SC205D application summary).
UnderCover SwingCase SC205D: who should not buy
Skip it if your daily kit weighs past the rating — a steel crossover box carries heavy tools better. This case is for the grab-daily kit, not the whole toolbox.
UnderCover SwingCase SC205D: pair it with
Pair it with rated straps and the shackles in Safety essentials; a Super Duty recovery kit is exactly the load this case was sized around. See also our winch sizing for 3/4-ton trucks.
We may earn a commission at no cost to you. Verified fitment: part SC205D, F-250 / F-350 Super Duty 2017–2025 driver side. Other Super Duty years use different part numbers.
Tip: weigh the loaded case once on a bathroom scale. Super Duty kits creep heavy, and staying inside 75 lb is what keeps the latch and hinge out of the watch-out list.
Best Budget: VEVOR Wheel Well Storage Box
Best Budget Swing-Out Box
Why the VEVOR Wheel Well Storage Box is our pick
The VEVOR box is the honest budget entry: an ABS wheel-well box for the Silverado driver side that keeps the core swing-case idea — dead-space storage, lockable lid, gear at the tailgate — and trades away the UnderCover platform’s tray finish and maker support depth. It adds one trick of its own, a password padlock alongside the key lock. Buy it with the watch-outs below in view and it is a fair trade; buy it expecting UnderCover polish and it is not.
VEVOR Wheel Well Storage Box key specs
- Type: wheel-well storage box, driver side (listing style: Chevrolet Silverado)
- Construction: ABS (listing material data)
- Storage volume: 6.6 gallons (listing; litre figure conflicts — see Sources)
- Dimensions: 28.3 x 8.7 x 15.4 in (listing mirror data)
- Maximum weight recommendation: 75 lb (listing)
- Item weight: 11 lb
- Locking: lockable lid with password padlock; key in the parts list
- Compartments: 2 (listing)
- Water resistance: listed as waterproof (maker wording, not a tested result)
- In the box: toolbox, screws, nuts, buckles, rubber pads, key (listing parts list)
- Warranty: not published in the listing data checked
VEVOR Wheel Well Storage Box: fits and best for
The verified listing is the Chevrolet Silverado driver-side style. It suits Silverado owners who want the wheel-well idea at a budget tier, and as the check-first alternative for GM owners whose trucks fall outside the SC104D exclusions — with clearance confirmed with the seller before ordering, because this guide could not verify a MultiPro-specific VEVOR fitment either.
VEVOR Wheel Well Storage Box pros and watch-outs
Pros
- Lowest-cost route here into wheel-well storage
- Password padlock adds a second locking layer
- Light at 11 lb; easy to handle on and off
- Same 75 lb maximum class as the UnderCover line
- Two compartments help separate clean and dirty kit
Watch-outs
- No published warranty term in the listing data checked
- Volume litre figure conflicts between VEVOR listings (flagged in Sources)
- Owner coverage for this exact ASIN is thin
- Maker waterproof wording should be read as weather resistance
VEVOR Wheel Well Storage Box: what owners report
Owner coverage for this exact ASIN is thin in the sources checked, and this review invents none: the listing record and the maker’s own store data are what this pick stands on (VEVOR truck tool box store).
Platform-level expectations still apply: fit the bracket carefully, keep loads inside the listed maximum, and treat the seal as weather protection.
VEVOR Wheel Well Storage Box: who should not buy
Skip it if warranty support matters to you — the UnderCover picks carry a stated one-year term and a US support team. Skip it, too, if you need a verified MultiPro or Carbon Pro answer; neither box in this guide verifies one.
VEVOR Wheel Well Storage Box: pair it with
Pair it with a dry bag inside for the items that must stay dry, and the tie-down habit from our essential winching accessories guide for everything else in the bed.
We may earn a commission at no cost to you. Verified fitment: VEVOR wheel well box, Chevrolet Silverado driver side per the listing style field. Confirm your generation and tailgate variant with the seller before ordering.
Tip: set the padlock combination and record it outside the truck on day one; a budget box with a forgotten code becomes a very secure paperweight.
Best for Older F-150: UnderCover SwingCase SC201D
Best Swing Case for Older F-150
Why the UnderCover SwingCase SC201D is our pick
The SC201D is the case for the F-150 generations that built the platform’s reputation: 1999–2014 trucks, driver side. Older trucks gain the most from a swing case, because their cabs store the least and their beds have usually carried a decade of loose gear. The part is still a current listing with the platform ratings, not a clearance leftover.

UnderCover SwingCase SC201D: fits and best for
The verified listing fits Ford F-150 trucks, 1999 to 2014, driver side; the passenger sibling is the SC201P, verified in the fitment table. Retailer feature copy for this generation walks through the same swing, seal and lift-off behaviour as the current parts (retailer SwingCase feature summary, 2009–2014 F-150). It suits older work and farm trucks whose owners plan to keep them.
UnderCover SwingCase SC201D pros and watch-outs
Pros
- Full platform ratings on a previous-generation fitment
- Transforms the least-organised beds in this guide
- Passenger sibling available for a matched pair
- Deep listing history for this part number
- Same tonneau compatibility claim as the line
Watch-outs
- Digest watch-outs are most detailed for this generation: latch wear, swing-back, lid hold-open
- One-year warranty on a part owners keep for a decade
- Check bed corrosion at the bracket points on older trucks
- ABS shows its age in sun sooner than steel
UnderCover SwingCase SC201D: what owners report
Buyer-report digests praise the same point owners of the wider line repeat: gear reachable from the tailgate without climbing in, and an install most finish in about half an hour (retailer editorial digest of SwingCase buyer reports).
The watch-outs in those digests are consistent: the receiving latch can wear, a heavily loaded case can sag on rough roads, and some owners hold the case or lid open because it can swing back (retailer editorial digest, SC201D). Treat these as digest summaries, not forum consensus — dedicated owner threads for individual fitments are thin.
UnderCover SwingCase SC201D: who should not buy
Skip it if the bed sides are rusted at the bracket line — fix the metal first, or choose a loose-bin setup until the truck is repaired.
UnderCover SwingCase SC201D: pair it with
Pair it with the maintenance habit in our maintenance checklist: the same monthly walk-around that checks a winch should check this case’s latch and bracket screws.
We may earn a commission at no cost to you. Verified fitment: part SC201D, F-150 1999–2014 driver side. The passenger-side sibling is part SC201P.
Tip: on an older bed, run a wire brush over the bracket area and touch up the paint before the screws go in; the bracket is only as solid as the metal under it.

Fitment & installation
Installation is a bracket job, not a build: the truck bracket fixes at the rear of the bed side with the supplied screws — six self-tapping screws on the UnderCover platform — the striker bracket sets the latched position over the wheel well, and the case drops onto its hinge. Maker copy says minutes and no special tools; the F-150 install sheet lists sockets and Torx bits, and buyer digests put a careful first install at about half an hour. Work in this order: dry-fit the bracket, swing the empty case through its full arc, check liner and tonneau clearance, then load it.
Three fitment traps decide success. First, side: driver and passenger cases are mirror mouldings. Second, exclusions: the GM part excludes Carbon Pro beds and MultiPro tailgates in its own title, and RamBox beds need confirmation on the Ram part. Third, liners: spray-in texture is usually fine, while thick drop-in liners can need a trim at the bracket, as owner summaries describe. Bed-mounted gear shares this space, so read our bed winch mounting guide, the mounting plate guide and our truck winch installation guide before brackets and mounts start competing for the same bed wall.
Safety essentials
Six rules for living with a swing case
- Latch the case shut before driving, every time: an unlatched case swings under braking and cornering.
- Stay inside the 75 lb rating, heavy items low and toward the hinge; an overloaded case sags and wears its latch.
- Keep fingers clear of the hinge and latch as the loaded case swings out — it moves faster than it looks.
- Never store fuel, solvents or loose lithium batteries in a closed case in a hot bed; heat and fumes collect.
- A lockable ABS lid is a deterrent, not a safe: firearms, documents and high-value tools belong in the cab or out of the truck.
- Re-check bracket screws after the first week and monthly on rough roads; a loose bracket is the start of every rattle and sag.
A swing case earns its space by what it stores. These three recovery staples are the load most owners describe, each with a verified listing from this site’s pool:
WARN Epic snatch block — doubles a winch pull and changes its direction; it is the bulkiest item in a typical case, so it goes on the case floor first.
Check Price: WARN Epic Snatch Block
GearAmerica tree saver strap — protects the anchor tree and the rope; coils flat in the tray or beside the block.
Check Price: GearAmerica Tree Saver
AMBULL shackles — the connection points for both; keep them in the sliding tray where they can be counted at a glance.
Round out the kit through our accessories archive, recovery kit guide and essential winching accessories guide; gloves and a tyre kit are named without buttons, as no listing for them was verified for this guide.
Troubleshooting common swing case problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Case sags or sits low when loaded | Load past the honest working weight, or bracket screws loose | Weigh the load and cut it toward 50 lb of daily kit; re-torque the bracket screws in sequence |
| Latch will not engage | Case overfilled, tray fouling the lid, or striker bracket shifted | Repack with the tray seated, then re-align the striker bracket until the latch clicks positively |
| Case swings back while loading | Truck parked on a slope, or hinge friction worn | Park level when loading, hold the case or chock it with the tailgate load; inspect the hinge for wear |
| Water inside after rain or a wash | Lid seal compressed, dirty or nicked; case parked nose-down | Clean the seal, check for nicks, replace the seal strip if it stays flat; keep the lid latch fully closed |
| Rattle on rough roads | Loose bracket, empty case, or hard items loose inside | Re-torque the bracket, add the tray back, and wrap hard tools so they cannot drum on the ABS |
| Bracket screws spin or pull out | Overtightened self-tappers, or corroded bed metal on older trucks | Move to sound metal, use the maker hardware only, and treat corrosion before refitting |
Who should NOT buy these swing cases
Anyone whose kit is bulky or heavy. Two cubic feet and a 75 lb rating is a daily-kit box. Trade tool sets, compressors and bulk recovery gear belong in a crossover box or drawer system — forcing them into a swing case buys the sag and latch wear the digests describe.
Carbon Pro and MultiPro owners ordering the GM part anyway. The SC104D listing excludes both, in its title. If your Sierra or Silverado is one of those trucks, do not order it and hope; use the finder above and confirm an alternative’s clearance first. The same caution runs through our Sierra bed cover guide.
Anyone expecting safe-grade security. A key-lockable ABS lid behind a tailgate deters and conceals. It does not resist a determined thief with time and tools, and no case here should be sold to yourself as doing so. Our winch value guide makes the same honesty point about security claims on recovery gear.
RamBox owners who will not confirm fitment. The RamBox bed is already a storage system with its own rails and boxes. If the listing does not confirm your exact bed, the case is a return waiting to happen — confirm first, or keep the factory system.

FAQ
What is a truck bed swing case?
It is a storage box moulded to sit over the rear wheel well, in the space between the wheel well and the tailgate that other boxes waste. It latches there for travel, swings out nearly 180 degrees to the tailgate for access, and on the UnderCover platform lifts off its hinge without tools. Each case here is rated by its maker at 75 lb of cargo.
Will a swing case work with my tonneau cover?
UnderCover states the SwingCase keeps about three inches of clearance and works with virtually all tonneau covers — soft, hard, folding and rolling. The case sits below the rails, so most covers close over it. Check the rear corner of your specific cover once fitted, and see our bed cover research linked in the reviews for how the covers themselves differ.
How much can a swing case actually hold?
By volume, roughly two cubic feet on the UnderCover platform — a recovery kit, strap set, jump leads, tyre kit and hand tools is a realistic load. By weight, the maker rating is 75 lb, and owner digests suggest treating about 50 lb as the comfortable daily load on rough roads if you want the latch and hinge to live a long life.
Driver side or passenger side: which should I buy?
Buy the side you load from. Most owners work at the tailgate and reach the driver side first, and most verified listings in this guide are driver side. Passenger side suits trucks parked tight on the driver side, or a second case in a pair. The parts are mirror mouldings, so the side must be chosen before ordering, not at fitting.
Can I fit two swing cases in one truck?
Yes — the platform is sold per side for exactly that. One case per wheel well, each within its own 75 lb rating, doubles the organised storage while the bed floor between the wheel wells stays clear for full-width loads. Start with one and add the second when the first is genuinely full.
Is a swing case secure and waterproof?
Secure enough to deter, not to defeat. The lid is key-lockable and the case hides behind the tailgate, which stops casual theft and keeps gear out of sight. The moisture seal keeps spray and dust off the contents, but no maker here warrants the case as submersible; treat it as weather-resistant and keep must-stay-dry items in a dry bag inside.
Will the SC104D fit my Sierra with a MultiPro tailgate?
No. The SC104D listing states in its title that it will not fit Carbon Pro beds or MultiPro tailgate trucks. That exclusion is the single most important line in this guide for Sierra owners. Confirm your tailgate and bed material before ordering any GM swing case, and use the fitment finder above for the alternatives.
Does a swing case fit with a bed liner?
Usually, with a check. Spray-in liners are thin and rarely interfere. Thick drop-in liners can foul the bracket at the rear wheel well, and owner summaries describe trimming the liner locally to seat the bracket. Dry-fit the bracket against your liner before any screws go in, and trim the minimum that lets it sit flat.
Swing case or crossover toolbox: which is better?
They solve different problems. A crossover box carries more, including long and heavy tools, but eats bed length behind the cab and means climbing in to reach the middle. A swing case carries less, but uses dead space, keeps the full bed length, and brings the gear to the tailgate. Many work trucks honestly need the crossover; most daily and recovery kits fit the swing case better.
