RockJock's Driver Lift Kit for JT Gladiators with the EcoDiesel engine provides 3 1/2 inches of lift and allows for efficient clearance of up to 37 in. tall tires (larger tires will require aftermarket fenders and minor trimming)!
Comprised of only the highest end components in the areas of strength, fit, finish, function, and the engineering to back them, this kit is more than sufficient for those who want to lift their vehicle, install big tires and maybe hit some dirt roads while overlanding! Included in this kit are our front control arm geometry correction brackets that will restore drivability to the stock feel after lifting, so everyday driving we be just as pleasurable as it was before the lift.
For those who intend to do more serious 4 wheeling and rock crawling, you'll want to look at all of the upgrade parts that RockJock has to offer that can be added to this kit to get your vehicle to it's full potential at any level of off-roading!
Premium shock packages from Fox and King are offered here as options so that you can select the shock brand and performance level that matches your driving style. We always recommend adjustable shocks, as they allow the ride to be tuned to match the terrain and driver’s preference.

Kit Features:
RockJock Spec.

Bump Stop Spacers - Proper bu
