Jeep Gladiator Generations: A Look at the JT Pickup's Evolution

The Jeep Gladiator returned for the 2020 model year as a midsize pickup with a design that was more than just a stretched Wrangler. It featured a unique rear frame and specific payload ratings. S. for six model years, and tracking its changes shows a focus on chassis adaptation and technology integration.

The first generation (JT) launched in mid-2019 for 2020, combining the Wrangler JL's front end with a bespoke high-strength steel rear frame. 3 inches, making the truck 218 inches long with a curb weight of 5,031 pounds. All trims came with heavy-duty Dana 44 axles and a five-link coil suspension, with rear control arms borrowed from the Ram 1500 for better load handling.

6-liter Pentastar V6 producing 285 horsepower and 260 lb-ft of torque, paired with either a six-speed manual or eight-speed automatic. 10 axle ratios, a Trac-Lok limited-slip rear differential, a 240-amp alternator, and heavy-duty cooling, boosting towing to 7,700 pounds and payload to 1,700 pounds on select trims.

0-liter EcoDiesel V6 became available with 260 hp and 442 lb-ft of torque, but it reduced payload and towing due to its heavier engine block.

Trim levels ranged from the base Sport to the Willys and Overland, with Rubicon and Mojave variants offering different off-road strengths. 0:1 low-range ratio, front and rear electronic lockers, and a sway-bar disconnect. 5-inch internal bypass shocks with hydraulic jounce bumpers.

Despite the hardware, the early JT had limitations. 9 degrees), and rear overhang led to departure angles of 25 to 26 degrees. Owners complained about wind noise, vague steering, and a stiff rear when the bed was empty. The truck is still the only convertible pickup and the sole midsize truck with a solid front axle.

A facelift arrived for 2024, focusing on technology and safety rather than mechanical changes. 3-inch touchscreen with Uconnect 5, wireless Apple CarPlay and Android Auto, and a redesigned dashboard with slimmer HVAC vents. Side curtain airbags became standard, requiring structural reinforcements in the B-pillars and roof rails.

Sport S and higher trims added forward collision warning and adaptive cruise control.

The exterior saw a slimmer seven-slot grille with textured slots and a body-color surround, aimed at better airflow and engine cooling. The steel antenna was replaced with one integrated into the windshield. 6-liter V6 as the only option. The manual transmission was discontinued for 2025, making the eight-speed automatic standard.

New 12-way power-adjustable front seats were sealed and waterproofed to maintain 30-inch water-fording capability.

The Mojave X and Rubicon X trims added Nappa leather seats and acoustic glass. Both came with steel bumpers, an off-road camera, and Rock-Trac or Selec-Trac transfer cases. Stellantis also partnered with American Expedition Vehicles (AEV) for three factory upfit packages. 5-inch lift, 37-inch tires, a Warn winch, and a front skid plate, pushing the approach angle to 57 degrees.

The Gladiator remains a specialized tool in a segment filled with more conventional daily drivers. It sacrifices highway refinement and breakover clearance but offers unmatched mechanical capability, towing and payload numbers, and aftermarket support.
