Listed for sale on Bring a Trailer, this 2025 Jeep Gladiator Rubicon has been extensively re-engineered by America’s Most Wanted 4×4 (AMW 4×4) in Burton, Michigan, transforming the factory midsize pickup into a high-output, heavily modified off-road machine. The centerpiece is AMW’s 505 Powertrain package, which replaces the Gladiator’s original engine with a 6.4-liter Hemi crate V8.
The V8 is paired with a retrofitted ZF 8HP75 eight-speed automatic transmission equipped with an AMW TrueShift manual-shift-mode kit. Supporting modifications include an AMW powertrain calibration, deep rear-sump oil pan, high-output alternator, high-flow power-steering system, high-torque starter, S&B air intake, high-flow fuel pump, and SRT exhaust manifolds. A 3.5-inch stainless-steel exhaust completes the powertrain installation.
Power is delivered through the Gladiator Rubicon’s Rock-Trac dual-range transfer case and Tru-Lok locking differentials at both axles. Chassis modifications include a 3.5-inch Rubicon Express suspension lift with Falcon shocks, a TeraFlex steering stabilizer, and 20-inch Fuel wheels wrapped in massive 38×13.5-inch Nitto Ridge Grappler tires.
Visually, the truck has been refinished in green-tinted Rhino Liner bedliner material accented by bronze details. Its aggressive hardware includes a Fab Fours front bumper, Smittybilt winch, Factor 55 FlatLink, roof-mounted LED light bar, Rigid Industries cube lights, Oracle taillights, Road Armor Stealth fender flares, and a DV8 Offroad rear bumper and inner fenders. Power-deployable side steps and the removable three-piece hardtop add practicality.
The cabin receives a more upscale treatment with brown Alea Leather upholstery, quilted diamond-stitched inserts, and white piping. Matching trim extends across the dashboard, console lid, and door armrests. Heated seats, dual-zone automatic climate control, adaptive cruise control, a forward-facing off-road camera, Alpine premium audio, and a 12.3-inch Uconnect 5 touchscreen with navigation, Apple CarPlay, and Android Auto provide modern functionality.
The result is a Gladiator that combines factory Rubicon hardware with substantial AMW engineering, V8 power, upgraded driveline components, and the hardware necessary to exploit its increased off-road capability.
