How we researched this guide
We compared 5 Jeep Gladiator accessories and checked 5 Amazon listing tables for fitment, part numbers, lift conditions and warranty wording. Every pick is verified Gladiator JT fitment on its listing; Nashville in the title is keyword noise, and no Nashville store, installer or local claim is made anywhere here.
No verified Gladiator-specific WeatherTech Amazon ASIN was found in this research, so no WeatherTech pick appears here and the universal trim-to-fit mat is deliberately not used as a Gladiator pick. Lift-height and tonneau-cover conditions on the listings are load-bearing and are carried into every affected pick.
The 30-second answer
For a Gladiator JT, the Bestop Sunrider flip-top opens the roof, the Design Engineering headliner quiets the cab, the OTHOWE bed rack adds cargo space without a tonneau cover, the DS18 under-seat enclosure adds bass without losing cabin room, and the Superlift steering bundle upgrades steering and suspension for lifted trucks. Check the lift and tonneau conditions on the last two picks before ordering.

How to choose Jeep Gladiator accessories
Gladiator-specific fit, not just Jeep fit
Wrangler and Gladiator parts do not always interchange, so a part must name the Gladiator JT to be trusted here. Every pick in this guide names Gladiator JT fitment on its listing, with model years stated. A part that only says Jeep, or only names a Wrangler, is not a Gladiator pick and should not be ordered as one.
Lift-height conditions are load-bearing
The Superlift steering bundle carries different lift conditions per component: the stabilizer requires a 1.5-inch or greater lift, and the shock box is for a 4-inch lift, per the listing. Dropping those conditions would mis-fit a stock-height truck. Read the component conditions for your exact lift before ordering any bundle.
Tonneau-cover condition on the bed rack
The OTHOWE bed rack is listed for Gladiators without a tonneau cover, with factory bed rails, so a truck with a tonneau cover needs a different answer. Check your bed setup against that condition first, since a rack that conflicts with a tonneau cover is a return, not a workaround.
Cab space against cargo space
Cab accessories trade against each other: a headliner adds comfort without taking space, while an under-seat enclosure adds bass without losing cabin room. A bed rack adds cargo space outside the cab. Decide whether your constraint is cab room, bed room or noise, then pick the accessory that solves that constraint.
Install effort and help
A flip-top roof and a peel-and-stick headliner are cab jobs with different skill needs, while a steering bundle touches steering and suspension and deserves a careful installer. Judge each pick by the install it actually needs, not by the product photo, and get qualified help for steering and suspension work.
Warranty wording on the listing
Warranty descriptions here come from the listings: the Bestop top lists a limited lifetime manufacturer warranty description, and the OTHOWE rack lists a 2-year manufacturer warranty description. Warranty wording is a listing claim, not a tested result, so read the listing terms before relying on it.
Fitment by Gladiator model and setup
| Pick | Fitment (listing) | Condition to check |
|---|---|---|
| Bestop Sunrider flip-top | 2018 to current Wrangler JL and Gladiator, hardtop | Hardtop model; black twill |
| Design Engineering headliner | Gladiator JT 2020-up | Pre-cut panels for JT cabs |
| OTHOWE bed rack | 2020 to 2025 Gladiator, factory bed rails | Without tonneau cover |
| DS18 under-seat enclosure | Gladiator and pickup trucks, under-seat | Under-seat space and amplifier wiring |
| Superlift steering bundle | 2020 to 2024 Gladiator JT | Lift-height conditions per component |
Gladiator accessories by budget
| Tier | What you get | Example pick |
|---|---|---|
| Cab comfort | A headliner kit that quiets the cab without taking space | Design Engineering Boom Mat Headliner Kit |
| Roof and bed | A flip-top roof plus a bed rack for open-air and cargo use | Bestop Sunrider for Hardtop |
| Suspension upgrade | A full steering and suspension bundle for a lifted truck | Superlift Deluxe Steering Upgrade Bundle |
Types of Gladiator accessories
| Type | Pros | Cons | Best for |
|---|---|---|---|
| Roof | Open-air driving without removing the hardtop | Hardtop models only | Hardtop Gladiator owners |
| Cab comfort | Less noise and heat, no space lost | Peel-and-stick install care needed | Daily-driven Gladiators |
| Bed cargo | Cargo space above the bed | Tonneau-cover conflict possible | Overland and work Gladiators |
| Audio | Bass without losing cabin room | Amplifier wiring needed | Music lovers keeping cabin space |
| Suspension and steering | Steering and ride upgrade for lifted trucks | Lift conditions apply per part | Lifted Gladiator builds |
Detailed reviews
Every pick below is verified Gladiator JT fitment on its Amazon listing, described only from listing evidence. Nashville is keyword noise in the title and is not treated as a location requirement anywhere here.
Best open-air roof pick: Bestop Sunrider for Hardtop, Black Twill, for Wrangler JL and Gladiator
Best open-air roof pick
Why the Bestop Sunrider is our pick
The Bestop Sunrider is the open-air answer for a hardtop Gladiator: a flip-back top that opens the roof without removing the hardtop. Its listing includes a pre-installed fabric-on-frame assembly plus door rails, and a limited lifetime manufacturer warranty description, which together make it the most complete roof pick in this guide.
Bestop Sunrider key specs
- Brand: Bestop
- Part: 5245417
- Colour: black twill
- Includes: pre-installed fabric-on-frame assembly plus door rails (listing)
- Operation: flip-back (listing)
- Fitment: 2018 to current Jeep Wrangler JL and Jeep Gladiator
- Warranty: limited lifetime manufacturer warranty description (listing)
- Amazon ASIN: B07JLZ2ZKR
Bestop Sunrider: fits and best for
Best for hardtop Gladiator owners who want open-air driving without full top removal. Confirm the hardtop model and the black twill finish before ordering, since this top is a hardtop product, not a soft-top replacement.
Bestop Sunrider pros and watch-outs
- Flip-back operation without removing the hardtop
- Pre-installed fabric-on-frame assembly
- Door rails included on the listing
- Fits 2018 to current JL and Gladiator hardtops
- Limited lifetime manufacturer warranty description
- Hardtop models only
- Black twill is the listed finish
- Roof install needs care around seals and rails
- No soft-top coverage
Bestop Sunrider: what owners report
Owner-report coverage in the research notes is thin: no independent owner-source quotes were retrieved for this product, so this guide makes no owner-report claim for it. The listing page is linked in Sources for readers who want to read owner reports there.
Bestop Sunrider: who should not buy
Do not buy this top for a soft-top Gladiator or for a non-hardtop setup. It is a hardtop flip-top, and the wrong top type is a certain mis-fit.
Bestop Sunrider: pair it with
Pair it with a seal check after fitting, so the flip-back top closes cleanly against the hardtop rails.

Confirm hardtop fitment first; see our best Jeep Gladiator accessories pillar guide for the wider Gladiator range.
Best cab comfort pick: Design Engineering Boom Mat Sound Deadening Headliner Kit, for Gladiator JT 2020-Up
Best cab comfort pick
Why the Design Engineering headliner is our pick
The Design Engineering headliner is the cab-comfort pick: pre-cut peel-and-stick acoustic and thermal panels made for the Gladiator JT 2020-up cab. It adds noise and vibration reduction without taking cabin space, which suits a daily-driven Gladiator better than a bulkier cab treatment.
Design Engineering headliner key specs
- Brand: Design Engineering, Inc.
- Fitment: Jeep Gladiator JT 2020-up
- Type: peel-and-stick acoustic and thermal panels
- Cut: pre-cut for Gladiator JT
- Purpose in listing: noise and vibration reduction
- Amazon ASIN: B082Q8FXLD
Design Engineering headliner: fits and best for
Best for Gladiator JT 2020-up cabs where road and wind noise is the complaint. Confirm the JT model year, since the panels are pre-cut for that cab shape.
Design Engineering headliner pros and watch-outs
- Pre-cut for the Gladiator JT cab
- Peel-and-stick fitting, no special tools named
- Acoustic and thermal benefit in one kit
- No cabin space lost
- JT 2020-up only
- Peel-and-stick adhesion needs a clean surface
- Noise reduction is a listing claim, not a measured result here
- No warranty description published in the research notes
Design Engineering headliner: what owners report
Owner-report coverage in the research notes is thin: no independent owner-source quotes were retrieved for this product, so this guide makes no owner-report claim for it. The listing page is linked in Sources for readers who want to read owner reports there.
Design Engineering headliner: who should not buy
Do not buy this kit for a pre-2020 Gladiator or for a Wrangler cab, since the panels are pre-cut for the JT 2020-up shape. The wrong cab shape is a mis-fit.
Design Engineering headliner: pair it with
Pair it with a clean-surface prep pass before sticking any panel, since adhesion decides the result.

Best bed rack pick: OTHOWE 22.5-inch High Jeep Gladiator Bed Rack, for Gladiator JT Without Tonneau Cover
Best bed rack pick
Why the OTHOWE bed rack is our pick
The OTHOWE bed rack is the cargo answer for a Gladiator bed: a 22.5-inch high carbon steel rack with E-coating, mounting hardware and instructions on the listing, and a 2-year manufacturer warranty description. Its without-tonneau-cover condition is stated in the listing title itself, so it is carried plainly into this pick.
OTHOWE bed rack key specs
- Brand: OTHOWE
- Part: BR55935
- Height: 22.5 in
- Material: carbon steel with E-coating
- Includes: bed rack plus mounting hardware plus instructions (listing)
- Warranty: 2-year manufacturer warranty description (listing)
- Fitment: 2020 to 2025 Gladiator with factory bed rails
- Condition: without tonneau cover (listing title)
- Amazon ASIN: B0D3GJZGHF
OTHOWE bed rack: fits and best for
Best for 2020 to 2025 Gladiators with factory bed rails and no tonneau cover, used for overland or work cargo. Check the bed setup against both conditions before ordering.
OTHOWE bed rack pros and watch-outs
- 22.5-inch height for useful bed cargo space
- Carbon steel with E-coating
- Mounting hardware and instructions included
- 2-year manufacturer warranty description
- Clear 2020 to 2025 fitment list
- Without tonneau cover only, per the listing title
- Needs factory bed rails
- Bed rack adds height and wind exposure
- No load rating published in the research notes
OTHOWE bed rack: what owners report
Owner-report coverage in the research notes is thin: no independent owner-source quotes were retrieved for this product, so this guide makes no owner-report claim for it. The listing page is linked in Sources for readers who want to read owner reports there.
OTHOWE bed rack: who should not buy
Do not buy this rack for a Gladiator with a tonneau cover or without factory bed rails. Both conditions are listing requirements, and either one breaks the fit.
OTHOWE bed rack: pair it with
Pair it with a bed-load plan that keeps weight low and secured, since a rack does not make an unsecured load safe.
We may earn a commission at no cost to you.
Check tonneau and rail conditions first; see our best truck bed cover for Jeep Gladiator guide for bed cover options.
Best under-seat audio pick: DS18 Under-Seat 10-inch Shallow Subwoofer Enclosure, Loaded, for Gladiator and Pickup Trucks
Best under-seat audio pick
Why the DS18 enclosure is our pick
The DS18 enclosure is the audio pick that keeps the cabin usable: a loaded 10-inch shallow sealed enclosure that fits under the seat, so bass does not cost legroom or storage. Its listing power and volume figures are stated plainly, and the carpet finish suits a truck cabin.
DS18 enclosure key specs
- Brand: DS18
- Model: DFPU110IX
- Size: 10 in sealed enclosure
- Power: 600W RMS, 1200W max (listing)
- Impedance: 2-ohm
- Construction: 3/4-inch MDF
- Finish: carpet finish
- Volume: 0.32 cubic feet sealed volume (listing)
- Fitment: Jeep Gladiator and pickup trucks
- Amazon ASIN: B0FT4XDBQG
DS18 enclosure: fits and best for
Best for Gladiator owners who want under-seat bass while keeping cabin room. Confirm under-seat space and amplifier wiring against the listing figures before ordering.
DS18 enclosure pros and watch-outs
- Under-seat fit keeps cabin room
- Loaded enclosure, no separate subwoofer hunt
- 600W RMS and 1200W max on the listing
- Sealed 0.32 cubic foot volume for tight bass
- Carpet finish suits a truck cabin
- Needs amplifier wiring, not a plug-and-play speaker
- Under-seat space must be confirmed
- 2-ohm impedance must match the amplifier
- No warranty description published in the research notes
DS18 enclosure: what owners report
Owner-report coverage in the research notes is thin: no independent owner-source quotes were retrieved for this product, so this guide makes no owner-report claim for it. The listing page is linked in Sources for readers who want to read owner reports there.
DS18 enclosure: who should not buy
Do not buy this enclosure if under-seat space is already taken or the amplifier cannot match a 2-ohm load. Both checks come before ordering, not after.
DS18 enclosure: pair it with
Pair it with an amplifier match check for the 2-ohm load and the 600W RMS figure before any wiring work.
We may earn a commission at no cost to you.
Match the amplifier to 2 ohms first; see our best Jeep camping accessories guide for cab living.
Best steering upgrade pick: Superlift Deluxe Steering Upgrade Bundle for Gladiator JT, Bilstein Stabilizer plus Track Bars plus Fox 2.0 Shocks
Best steering upgrade pick
Why the Superlift bundle is our pick
The Superlift bundle is the steering and suspension answer for a lifted Gladiator JT: a four-item bundle with a Bilstein dual steering stabilizer, front and rear adjustable track bars and Fox 2.0 shocks. It is the most involved pick in this guide, and its lift-height conditions per component are carried in full, because they decide whether it fits at all.
Superlift bundle key specs
- Brand: SUPERLIFT (RealTruck and Superlift bundle)
- Items: bundle of 4 items (listing)
- Includes: Bilstein dual steering stabilizer, front and rear adjustable track bars, Fox 2.0 shocks
- Fitment: 2020 to 2024 Jeep Gladiator JT
- Front track bar: 2018 to 2024 JL, 2020 to 2024 JT (listing)
- Stabilizer condition: requires 1.5-inch or greater lift (listing)
- Shock box condition: for 4-inch lift (listing)
- Amazon ASIN: B0CZKKRDGB
Superlift bundle: fits and best for
Best for lifted 2020 to 2024 Gladiator JT builds that meet the component lift conditions. A stock-height Gladiator does not meet the stabilizer condition and should not order this bundle without checking.
Superlift bundle pros and watch-outs
- Four-item bundle covers stabilizer, track bars and shocks
- Adjustable track bars for lifted geometry
- Bilstein stabilizer plus Fox 2.0 shocks in one bundle
- Clear 2020 to 2024 JT fitment list
- Stabilizer requires a 1.5-inch or greater lift
- Shock box is for a 4-inch lift, per the listing
- Not a stock-height Gladiator bundle
- Steering and suspension work needs qualified fitting
Superlift bundle: what owners report
Owner-report coverage in the research notes is thin: no independent owner-source quotes were retrieved for this product, so this guide makes no owner-report claim for it. The listing page is linked in Sources for readers who want to read owner reports there.
Superlift bundle: who should not buy
Do not buy this bundle for a stock-height Gladiator, since the stabilizer condition alone rules it out. A stock truck needs a different steering answer, not this bundle.
Superlift bundle: pair it with
Pair it with a qualified installer check after fitting, since steering and suspension work affects handling and alignment.
We may earn a commission at no cost to you.
Check every component lift condition, not just the bundle title; see our best size winch for Jeep Gladiator guide for Gladiator sizing.
Spec comparison
How we weighed these picks: listing and maker evidence only. This is editorial judgement, not test results. No scores are assigned because no hands-on testing was done for this guide.

Fitment and installation basics
Fitting Gladiator accessories starts with the conditions, not the box. Confirm hardtop status for the Sunrider, JT model year for the headliner, tonneau and rail status for the bed rack, under-seat space and amplifier match for the enclosure, and every lift condition for the steering bundle. A part that fits the badge but not the condition is still a mis-fit, and the conditions in this guide are listing conditions, not suggestions.
Roof and headliner work needs seal and surface care, bed rack work needs a rail and bed check, and steering work needs qualified fitting with an alignment check. For Gladiator sizing and recovery context, see best size winch for Jeep Gladiator, best winch for Jeep Gladiator and best budget winch for Jeep Gladiator.
Safety essentials
- Verify Gladiator JT fitment and model year before ordering any pick.
- Respect every lift-height condition on the steering bundle, per component.
- Respect the without-tonneau-cover condition on the bed rack.
- Keep bed loads low, centred and secured on any rack.
- Match amplifier impedance and power before wiring any enclosure.
- Get steering and suspension work checked by a qualified installer.
For the roof answer, the Bestop Sunrider is the hardtop flip-top pick.
For bed cargo, the OTHOWE rack is the no-tonneau answer.
For Gladiator context, see best Jeep exterior accessories and best Jeep rear bumper.
Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Sunrider will not close cleanly | Seal or rail misalignment | Re-check rails and seals against the fitting steps, and refit if needed |
| Headliner panel lifts | Dirty or uneven surface | Clean the surface and re-apply, pressing the full panel area |
| Bed rack conflicts with cover | Tonneau cover fitted | This rack is listed without tonneau cover, so choose a different bed setup |
| Enclosure sounds weak | Amplifier mismatch or wiring fault | Check the 2-ohm match and the wiring before blaming the enclosure |
| Steering bundle will not fit | Lift condition not met | Check each component lift condition against your actual lift height |
| Noise remains after headliner | Noise source elsewhere | Check seals, tires and roof fit, since a headliner cannot fix every noise source |
Who should NOT buy these
Do not buy a Wrangler-only part as a Gladiator part. Jeep fitment is not Gladiator fitment, and a part that never names the JT should not be ordered for a JT. Every pick here names Gladiator JT fitment, and the pillar guide best Jeep Gladiator accessories is the wider Gladiator range to compare against.
Do not buy the steering bundle for a stock-height truck. The stabilizer requires a 1.5-inch or greater lift, and the shock box is for a 4-inch lift, so a stock truck fails the conditions. A stock-height Gladiator needs a different steering answer, not this bundle.
Do not buy the bed rack for a truck with a tonneau cover. The listing title itself states without tonneau cover, and a rack that conflicts with a cover is a return. Check the bed setup first, and see best Jeep accessories under 100 for smaller Gladiator additions.
Do not buy a WeatherTech mat on a universal listing for a Gladiator. Maker and retailer evidence exists for Gladiator-specific FloorLiner HP parts 4413131 and 4413132IM, but no verified Gladiator-specific Amazon ASIN was found, so no WeatherTech pick appears here. The universal trim-to-fit mat is deliberately not used as a Gladiator pick.

FAQ
Is this guide about Nashville stores or installers?
No. Nashville in the title is keyword noise, and no Nashville store, installer or local claim appears anywhere here. Every pick is chosen on Gladiator JT fitment from its Amazon listing, and the guide works the same wherever the truck is. No local service is recommended.
Will Wrangler accessories fit my Gladiator?
Not reliably. Wrangler and Gladiator parts differ, and a part must name the Gladiator JT to be trusted here. The Bestop top names both JL and Gladiator, but that dual naming is on its listing, not an assumption. A part that only names a Wrangler should not be ordered as a Gladiator part.
Can I fit the Superlift bundle on a stock Gladiator?
No, not as listed. The stabilizer requires a 1.5-inch or greater lift, and the shock box is for a 4-inch lift, per the listing. A stock-height truck fails those conditions, so it needs a different steering answer. Check every component condition against your actual lift height before ordering.
Does the OTHOWE rack work with a tonneau cover?
No. The listing title states the rack is for Gladiators without a tonneau cover, with factory bed rails. A truck with a tonneau cover needs a different bed setup, and forcing this rack against a cover is a mis-fit, not a workaround.
Why is there no WeatherTech pick here?
Because no verified Gladiator-specific WeatherTech Amazon ASIN was found in this research. Maker and retailer evidence exists for Gladiator-specific FloorLiner HP parts, but without a verified ASIN, this guide will not present a universal trim-to-fit mat as a Gladiator pick. The honest move is to omit the pick, not to substitute a universal one.
Does the headliner kit fit older Gladiators?
The kit is pre-cut for Gladiator JT 2020-up cabs, so it should not be ordered for a pre-2020 model or a different cab shape. Pre-cut panels match one cab shape, and the wrong shape leaves gaps or overlaps. Confirm the JT model year before ordering.
Will the DS18 enclosure fit under any Gladiator seat?
It is listed for Gladiator and pickup trucks as an under-seat enclosure, but under-seat space still varies, so confirm the space and the amplifier match first. The enclosure is 2-ohm with 600W RMS on the listing, so the amplifier must match that load. A mismatch is a wiring problem, not an enclosure fault.
What should I check before ordering any Gladiator accessory?
Check four things: Gladiator JT fitment with model years, the condition that applies to your truck, such as lift height or tonneau status, the space the part needs, and the install it requires. Most Gladiator mis-fits come from skipping one of those four checks, not from the product itself.
