“A JL Unlimited with 19.4 inches more wheelbase and a five-foot steel bed: the first Jeep pickup since the Comanche, and the only one whose roof, doors and windshield still come off. It tows and hauls like a midsize truck and crawls nearly like a Wrangler. Check the recall list before you check the paint.”

PART 01

Overview

Where it came from, why it matters, and how it changed year to year.

The story

Jeep went 27 years without a pickup. The Comanche left Toledo in June 1992, Chrysler handed trucks to Dodge, and the closest thing to a Jeep pickup was AEV's licensed Brute conversion. The Gladiator, revealed at the Los Angeles Auto Show on November 28, 2018 and sold as a 2020 model from spring 2019, ended that. It is a JL Unlimited from the B-pillar forward, on a new frame 31 inches longer than the four-door Wrangler's, with a five-foot steel bed behind. Doors, roof and windshield still come off. No other pickup offers that.

A WRANGLER WITH A BED

Jeep had been teasing this truck for years. A Scrambler pickup on a stretched Wrangler was shown to dealers in 2003, and a 2005 Gladiator concept with a VM diesel and a manual gearbox previewed the JK. The production JT took its name from the 1962–88 full-size Gladiator and rides on a 137.3-inch wheelbase, 19.4 inches longer than the four-door Wrangler's. The bed has four steel cross-members, an aluminum damped tailgate, an optional 400 W outlet and a full-size spare slung underneath. The grille slots were opened up for towing.

Under it, Jeep fitted third-generation Dana 44 axles front and rear and a five-link coil rear suspension with two upper and two lower forged control arms and a track bar. Launch coverage called that suspension exclusive to the Gladiator. Power came from the 285 hp 3.6 Pentastar V6 with Aisin's six-speed manual or the eight-speed automatic. The Max Tow package on the Sport rated the truck at 7,650 lb, with 4.10 gears and a wider axle track.

RUBICON, MOJAVE AND A DIESEL

The Rubicon has the hardware Wrangler people expect: the Rock-Trac transfer case with a 4:1 low range, Tru-Lok lockers at both ends, 4.10 gears, an electronic front sway-bar disconnect and 33-inch tires. The crawl ratio is 84.2:1 with the manual. On 4,190 Rubicon Launch Editions, Jeep's nod to Toledo's 419 area code, were offered for preorder on a single day, April 4, 2019. The Mojave followed in 2020 as Jeep's first 'Desert Rated' model. It gets 2.5-inch FOX internal-bypass shocks with external reservoirs, hydraulic front jounce bumpers and a rear locker that works at speed in 4-High. It is built for whoops, not ledges.

For 2021 the 3.0 EcoDiesel V6 arrived, with 260 hp, 442 lb-ft from 1,400 rpm and the eight-speed automatic only. Motor1 measured it at about 300 lb heavier than the gas truck, rated to tow 6,500 lb, and EPA-rated at 22/28/24 mpg against 17/22/19 for the automatic Pentastar. It lasted three model years. Jeep closed the chapter with 1,000 Rubicon FarOut editions for 2023, and the diesel was dropped after that.

THE 2024 REFRESH AND WHAT CAME AFTER

The 2024 update brought a seven-slot grille with narrower slots that Jeep says cools better, an antenna hidden in the windshield, a standard 12.3-inch Uconnect 5 screen, and standard first- and second-row curtain airbags with structural changes for side impacts. Mojave X and Rubicon X trims added steel bumpers, a full-time transfer case and an off-road camera. The Willys got a standard rear locker. AEV's Upcountry packages added a 2-inch lift and 35-inch BFGoodrich KO2s, and a Rubicon-only Level II package fitted 37s.

The six-speed manual was dropped for 2025. A Gladiator 4xe plug-in hybrid was announced for 2025 and then cancelled in September 2025. For 2026 a Sahara trim joined the range, and every Gladiator now uses the Pentastar with the automatic. Mopar Insiders lists 2026 prices from $38,830 for a Sport to $59,995 for a Rubicon X or Mojave X, before destination. For the Cherokee XJ and Comanche generation, a Jeep pickup costing that much would have seemed absurd. Owners don't seem to mind.

LIVING WITH THE LONG ONE

The extra wheelbase is the trade-off. Breakover is 18.4° on a stock Sport and 20.3° on a Rubicon, and the turning circle is 44.5–45 ft, so tight switchbacks can take a three-point turn, and the long belly between the axles is more exposed on ledges. In return the Gladiator is calmer on washboard, steadier with a trailer, and Jeep's first bed for a muddy cooler since the Comanche, and the spiritual heir of the CJ-8 Scrambler. Its natural rivals are other overland pickups such as the Ineos Quartermaster and the 70 Series pickups sold outside North America.

SIDEBAR · 27 YEARS WITHOUT A JEEP PICKUP

Why the Gladiator isn't called Comanche or Scrambler

Jeep's naming shortlist included Scrambler, Comanche and the Gladiator name of the 1962–88 J-Series trucks. Wikipedia suggests that Comanche's weaker brand recognition, and sensitivity to the Comanche Nation, likely counted against that name. Gladiator won.

The gap had been filled unofficially. From 2013 to 2017, American Expedition Vehicles built the Brute, a licensed double-cab Wrangler JK conversion. Once the JT arrived, AEV moved on to building upfit packages for it, including the Upcountry and Level II packs offered with the 2024 refresh.

Specs & capability

How it’s built, what it can do, and what fits under it.

How it’s built

The JT is a body-on-frame truck: a ladder frame under an open steel and aluminum body, with a 137.3-inch wheelbase and a separate five-foot bed. Both axles are solid Dana 44s on coil springs, located by four links and a track bar at each end. Steering is electro-hydraulic, with a 13.3:1 ratio. Every Gladiator is 4WD: part-time Command-Trac (2.72:1), full-time Selec-Trac on non-Rubicon trims, and the Rubicon's Rock-Trac (4:1) in part-time or full-time form.

Buying one

What to pay, what to check, and how to tell a good one from a clone.

What they cost

Still in production, so used prices follow new ones. Bring a Trailer results are dominated by engine-swapped builds, while stock trucks sell for well under the original sticker.

Stock driver (2020–21 gas)$22k–35k

Low-mile Rubicon / EcoDiesel$37k–48k

V8-swapped or 6x6 builds$45k–141k

New, 2026 MSRP (before destination)$38,830–59,995

Based on 16 Bring a Trailer sales from October 2025 to October 2026 (median $46,750, skewed by AMW Hellcat/Demon conversions; stock trucks sold for $21,750–45,000), plus Mopar Insiders' 2026 trim pricing from Sport to Rubicon X and Mojave X. Prices move; checked October 2026. See live listings below.

What to check before you buy

01
Run the VIN for recalls firstGladiators have had recalls for rear driveshafts (19V-636), manual clutches (20V-124, 21V-028, 23V-116 and 24V-572), EcoDiesel fuel pumps (22V-767, 23V-263), instrument clusters (24V-652) and, in June 2026, power-steering pump wiring that can start a fire with the truck parked (26V-363). Confirm each one is done.
02
Manual trucks: ask about the clutchThe clutch pressure plate can overheat and fracture. FCA first issued software, then replaced clutch assemblies under 23V-116, and some 2021 trucks needed a second software fix under 24V-572. Ask for dealer paperwork, not a shrug.
03
Drive it at 50–65 mph over a bumpGladiators can shimmy or wobble after a highway expansion joint, as JLs can. Owners on JeepGladiatorForum report dealers replacing the steering damper or the steering box. Any wobble means the front end needs inspecting before you hand over money.
04
Diesel? Check the fuel pump historyEcoDiesels were recalled twice for high-pressure fuel pumps that can fail and stall the engine. Look for the recall paperwork, ask about fuel-filter changes and look at the oil level. Diesel trucks are also about 300 lb heavier, so payload is lower.
05
Look under the bed and behind the bumpersCheck the frame, bed mounts and spare-tire carrier for damage from off-road use. Check the rock rails and skids for dents that hint at hard use, and the hitch area for signs of heavy towing.
06
Know which axle and gearing you're buyingSport and Overland trucks came with 3.73 gears and a narrower 62.9 in track. The Max Tow package, Rubicon and Mojave have 4.10 gears and wider track. Rubicons add front and rear lockers and the 4:1 transfer case. Check the window sticker or build sheet.
07
Lifted trucks: inspect the steering and track-bar mountsBig tires and lifts load the steering box, track bars and their mounts. Look for elongated holes, fresh paint on welds, and torque marks that have moved. Ask what was done to correct the track-bar geometry.
08
Hardtop and doorsMake sure the Freedom panels, hardtop seals and removable doors come with the truck and fit without leaking. Water stains on the carpet usually mean worn seals or poorly fitted panels.

Spotting the real thing

Every Gladiator looks much the same, but the trim decides the axles, gearing, transfer case and lockers. The difference between a Sport and a Rubicon is far more than badges.

ID
RubiconRock-Trac transfer case with 4:1 low range, front and rear Tru-Lok lockers, 4.10 gears, electronic sway-bar disconnect, LT285/70R17 tires and wide-track axles (64.4 in). Look for the locker and sway-bar switches on the dash.
ID
MojaveFOX 2.5 in internal-bypass shocks with external reservoirs, FOX hydraulic front jounce bumpers, 'Desert Rated' fender badges, orange tow hooks, 65.0 in track, rear locker that works at speed in 4-High. Command-Trac 2.72:1 low range, not Rock-Trac.
ID
Max Tow (Sport, Sport S)4.10 gears, wider 64.4 in track and the 7,650 lb rating (8-speed only, 2020 spec). Without it, Sports have 3.73 gears and a 62.9 in track.
ID
EcoDiesel2021–2023 only, automatic only and never on a Mojave. The 2023 Rubicon FarOut has a 'Diesel 3.0L' hood graphic; 1,000 were built.
ID
Pre- or post-20242024-on trucks have a seven-slot grille with narrower slots, no mast antenna (it's in the windshield), the 12.3 in Uconnect 5 screen and standard curtain airbags.
ID
Rubicon Launch Edition2020 only, 4,190 built (a nod to Toledo's 419 area code), with special badges and wheels and a leather-wrapped dash with red stitching.

Post-purchase baseline

After you buy it

Assume a used Gladiator has had oil changes and nothing else. Run the VIN through NHTSA's recall lookup first, then do the gear oils, transfer case and brake fluid, which owners most often skip. Fluid types below come from Mopar's specifications as compiled on JeepGladiatorForum and a 2021 owner's-manual excerpt posted there; engine capacities come from Stellantis's 2020 specification sheet. The EcoDiesel and Pentastar use different oils and filters.

For the hands-on owner

Common repairs

The jobs owners actually end up doing, rated for a competent home mechanic with a decent tool kit. Always confirm torque figures, fluids and procedures against the factory service manual for your VIN, and work safely — support the truck on stands, never just a jack. You do this work at your own risk; see the disclaimer. Some parts links are affiliate links.

Cure steering wobble: damper, track bar, steering box

DIFFICULTY · 2 / 5TIME · ≈ 1–3 hours to inspect and fit partsSHOP COST · Parts plus alignment; dealer work if under warranty

SYMPTOMSFront-end shimmy or full death wobble after a bump at highway speed, or a steering wheel that shakes side to side. JeepGladiatorForum owners report dealers finding a weak damper or play in the steering box.

THE FIXInspect before you buy parts. With the truck on its wheels and the engine running, have a helper rock the steering wheel while you watch both ends of the front track bar, the tie-rod and drag-link ends, the pitman arm and the steering box mounting. Check ball joints and wheel bearings with the front end raised. Replace what's worn, torque the suspension at ride height, then get an alignment. A new damper helps a weak original, but on its own it only hides wobble. On lifted trucks, an adjustable track bar re-centers the axle.

THE FIXRemove the engine cover and air intake, then the upper intake manifold and lower intake runners to reach the valley. Disconnect the sensors on the housing, unbolt it, clean the valley thoroughly and fit the new housing with new seals. Refit the intake with new gaskets, refill oil and coolant, bleed the cooling system and check for leaks. Don't over-tighten the plastic filter cap.

Power steering: recall check, then hoses and reservoir

DIFFICULTY · 3 / 5TIME · ≈ 2 hours DIY; recall work at the dealerSHOP COST · Free under recall 26V-363 where it applies

SYMPTOMSLoss of power assist, a 'Service Power Steering' warning, fluid weeping from the hoses or reservoir, or a burning smell. NHTSA's June 2026 recall 26V-363 covers 2021–2025 Wranglers and Gladiators whose electro-hydraulic pump wiring can overheat and start a fire, even when parked.

THE FIXCheck the VIN on NHTSA's lookup first. If 26V-363 applies, the dealer does the repair; until then, park outside. Out of recall, find leaks with the engine cold: clean the area, run the engine and turn lock to lock, then look at the hose crimps and reservoir. To replace a hose, drain the reservoir, swap the hose with new O-rings, refill with Mopar power-steering fluid (MS-11655 per the forum's Mopar fluid list) and bleed by turning lock to lock.

EcoDiesel: fuel-pump recalls and fuel-filter service

DIFFICULTY · 2 / 5TIME · ≈ 1 hour for the filterSHOP COST · Recall work free; a fuel filter for routine service

SYMPTOMSStalling, hard starting or a diesel smell on a 2021–2023 EcoDiesel. NHTSA recalls 22V-767 and 23V-263 cover high-pressure fuel pumps that may fail and stall the engine.

THE FIXConfirm both recalls are closed. Then treat the fuel filter as a wear item, because the high-pressure pump is sensitive to water and dirt. Relieve fuel pressure, replace the filter element and seals, prime the system as the service manual describes, and check for leaks. Drain water from the separator if the warning light comes on.

Manual trucks: clutch recall status, then clutch replacement

DIFFICULTY · 4 / 5TIME · ≈ A daySHOP COST · Free under recall where open; otherwise a clutch kit and a long day

SYMPTOMSA burning smell after slow off-road work or towing, slipping, or a 'clutch overheating' message. NHTSA recalls 20V-124, 21V-028 and 23V-116 cover pressure plates that can overheat and fracture on 2020–2023 manual Gladiators.

THE FIXCheck the recalls first; the dealer remedy is a new clutch assembly and software. For a worn clutch on a truck that's already been remedied, support the truck, drop the front and rear driveshafts and the transfer case, unbolt the starter and bellhousing, and lower the transmission. Fit the new clutch and flywheel to the manufacturer's specifications, refit everything, bleed the hydraulics and follow the service manual for any clutch or software relearn.

Driveshafts: recall check and U-joint service

DIFFICULTY · 2 / 5TIME · ≈ 1–2 hoursSHOP COST · Recall replacement free; U-joints or a CV shaft otherwise

SYMPTOMSVibration under acceleration, a clunk on take-off, or a squeak from the driveshafts. Recall 19V-636 covered 2020 Gladiators built between December 15, 2018 and June 25, 2019 whose rear driveshaft monoblock joint may have been assembled without grease. Wikipedia counts about 3,427 trucks.

THE FIXConfirm 19V-636 on early trucks. Then grab each driveshaft and twist: any clunk or play at the U-joints means replacement. Mark the shaft's position, unbolt it, press out the old joint and press in the new one with new clips. On lifted trucks, steeper angles may call for a CV-style shaft.

Re-spring the rear for a real load

DIFFICULTY · 2 / 5TIME · ≈ 2–3 hours for rear coilsSHOP COST · A pair of coils, or a full lift kit

SYMPTOMSThe rear sags or bottoms out once a camper shell, bed rack, rooftop tent or trailer is added. Payload is as low as 1,105 lb on a 2020 Sport automatic with 3.73 gears, per Stellantis's specification sheet.

THE FIXWeigh the loaded truck at a scale first. Then fit coils rated for the load: support the frame, unbolt the shocks, sway-bar links and brake-line brackets, lower the axle carefully, swap the coils and isolators, and refit at ride height before torquing the bushings. Check the rear track bar and driveshaft angle afterwards, and re-aim the headlights.

Asked on every forum

Jeep Gladiator JT questions, answered

What's the biggest tire I can fit without a lift?

On a Rubicon or Mojave, a 35x11.50R17 on the stock 17x7.5 wheel, per Drivingline's Rubicon fitment guide, which also says 37s need at least a 1-inch front spacer and bump stops and still rub off-road. On Sport and Sport S trucks, JeepGladiatorForum owners run 33s (285/70R17) without rubbing. Some say 35s work on stock suspension with little rubbing; others say they hit the flares at full flex.

Gas or EcoDiesel?

The 2021–23 EcoDiesel makes 442 lb-ft from 1,400 rpm and rates 22/28/24 mpg against 17/22/19 for the automatic Pentastar. But it's about 300 lb heavier, tows less (6,500 lb, or 6,000 lb on a Rubicon), was automatic-only, and has had two fuel-pump recalls. Pick the diesel for range and low-speed torque; pick the gas truck for maximum towing and simpler ownership.

SOURCE · MOTOR1 · NHTSA

How much can it tow and carry?

Stellantis's 2020 specification sheet rates a Sport automatic with 4.10 gears (the Max Tow package) at 7,650 lb and a Rubicon automatic at 7,000 lb. Manual trucks are rated 4,000–4,500 lb. Payload runs from 1,105 lb to 1,700 lb depending on trim and gearbox. For 2026, Mopar Insiders quotes up to 7,700 lb towing and 1,720 lb payload.

Rubicon or Mojave?

The Rubicon is for rocks: 4:1 low range, front and rear lockers and a disconnecting front sway bar. The Mojave is for speed on rough dirt: 2.5-inch FOX internal-bypass shocks with reservoirs, hydraulic front jounce bumpers, 2.72:1 low range and a rear locker that works at speed in 4-High.

Has the Gladiator had frame or track-bar recalls?

As of October 2026, NHTSA's recall list for 2020–2026 Gladiators shows no frame-weld or track-bar recall. The well-known track-bar bracket weld recall (18V-675) covered 2018–2019 Wranglers, before the JT existed. Gladiator recalls have instead covered driveshafts, clutches, fuel pumps, the instrument cluster, cameras, seat belts, steel wheels (2026) and power-steering pump wiring.

SOURCE · NHTSA

Does it get death wobble?

Some do. JeepGladiatorForum owners report wobble on new trucks, with dealers replacing the steering damper or the steering box. Treat it as a front-end inspection, not a damper purchase: check the track bar, tie-rod and drag-link ends, ball joints and the steering box mount.

SOURCE · JEEPGLADIATORFORUM

What changed for 2024?

A seven-slot grille, an antenna in the windshield, a standard 12.3-inch Uconnect 5 screen, standard first- and second-row curtain airbags with side-impact structural changes, new Mojave X and Rubicon X trims, a standard rear locker on the Willys, and AEV upfit packages with 35- or 37-inch tires. The diesel was gone.

SOURCE · MOTOR1 · PICKUP TRUCK TALK

What fuel economy should I expect?

EPA ratings for the 3.6 are 17/22/19 mpg with the automatic and 16/23/19 with the manual. The EcoDiesel is rated 22/28/24, or 21/27/24 as a Rubicon. Big tires, lifts and racks take more.

SOURCE · STELLANTIS · MOTOR1

What fluids does it take?

Per Mopar's specs as compiled on JeepGladiatorForum: 3.6 oil 0W-20 (MS-6395), OAT coolant, ZF-approved ATF in the eight-speed, ATF+4 in the manual and transfer case, 75W-85 GL-5 in both axles (75W-140 in the rear for towing), friction modifier with Trac-Lok, MS-11655 power steering fluid and DOT 3 brake fluid. See 'After you buy it'.

SOURCE · JEEPGLADIATORFORUM

Is the long wheelbase a problem off-road?

Sometimes. Breakover is 18.4° on a Sport and 20.3° on a Rubicon, and the turning circle is 44.5–45 ft, so tight trails take more shuffling than in a Wrangler. Rock sliders matter more on a Gladiator than on a Wrangler.

SOURCE · STELLANTIS

Manual or automatic?

The six-speed manual is rare and was dropped for 2025. It's also the gearbox with the clutch recalls and the lower tow ratings. The eight-speed automatic tows more and was the only choice with the diesel.
