Extensively modified for off-road performance, this 2012 Jeep Wrangler Unlimited Sport 4×4 features upgraded Dynatrac axles, 5.13 gearing, and a 3-inch suspension lift with extensive supporting modifications across the drivetrain, suspension, and interior. Offered by a private seller in Palm Desert, California for $39,995, this manual-transmission JK has received full fluid service and presents as a turnkey, trail-ready build.
- Serious Drivetrain & Axle Upgrades: Dynatrac ProRock 44 front and ProRock 60 rear axles with Eaton E-lockers and 5.13 gears transform this Wrangler into a highly capable off-road platform. Paired with a Centerforce II clutch and B&M precision shifter, the drivetrain is built to handle larger tires and demanding terrain with improved durability and control.
- Suspension, Wheels & Braking: A Teraflex 3-inch suspension lift with Falcon shocks supports 37-inch Nitto Ridge Grapplers mounted on KMC XD wheels. Stopping power is addressed with a Teraflex big brake kit, PowerStop components, and upgraded brake lines, providing improved confidence both on- and off-road.
- Armor & Exterior Equipment: Addictive Desert Designs bumpers, Road Armor fender flares with integrated DRLs, rock sliders with LED steps, and a Badland Apex 12,000-lb winch reinforce the Jeep’s off-road intent. Additional upgrades include Reaper fender liners, Morimoto LED headlights, and a Magnaflow exhaust system.
- Interior & Tech Upgrades: The cabin features Katzkin leather seats, a Stinger Heigh10 infotainment system, Alpine audio upgrades, and multiple camera systems including infrared night vision and off-road side cameras. Additional enhancements include a digital dash, push-button start, and sound-deadening treatment.
About the Jeep Wrangler JK
Introduced for the 2007 model year, the Wrangler JK marked a major evolution for Jeep, offering a longer wheelbase, improved on-road comfort, and the first-ever four-door Wrangler Unlimited. By 2012, the platform received the 3.6L Pentastar V6—delivering improved horsepower, efficiency, and reliability over earlier engines. With solid front and rear axles, body-on-frame construction, and a robust aftermarket ecosystem, the JK remains one of the most versatile and widely modified 4×4 platforms on the market.
