The Rock Krawler Suspension JT 3.0 inch ADVENTURE Mid-Arm System is specifically designed for Sport/Overland owners who want a complete system, bolt-in installation, and some of the best articulation of any MID-ARM kit on the market. Our system proves its durability and off-road performance every time you hits the streets or trail! The Term, "Adventure System" comes from the inclusion of 2 non-adjustable control arms with our 100% Service Free Adventure Series joints installed. Our industry leading, Adventure series mid-Arms offer a total of 70 degrees of misalignment when paired with our Adventure series Joints at the frame connection and at the axle. The inherent bind in a factory JL/JT control arm is greatly reduced.

Driving you home with the most comfortable ride possible in a Gladiator, are our TRIPLE RATE front coils and QUAD RATE rear coils. All 4 coils work together to achieve excellent on-road comfort that we feel is better than the OEM springs. The coil itself is built with the proper "Free-length" for off-road articulation and stays firmly seated in the coil bucket (as long as a proper length shock is installed), and overall, a very controlled reaction to bumps, rocks, sand, mud and whatever else you can manage to throw at them! All Rock Krawler JT systems include correction pads that reduce the spring bow inherent in the factory set up. The provided track bar geometry corrections, both front and rear, lets you perfectly center the axles so there is no compromise in on road handling.

General Notes:

All lift heights based on Rubicon models for standard style build (i.e. front bumper and winch, rear bumper and full size spare).
If building with a spare delete we recommend dropping 1” in coil lift height for the rear.
If building an "overland style" or heavily up-fitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
We recommend a new front driveshaft if you plan to off-road routinely. (Adam's Driveshaft, Tom Woods ,J.E. Reel)
