READ BELOW: EVERYTHING YOU NEED TO KNOW!

The Rock Krawler Suspension JK Wrangler 2.5 inch Adventure Mid-Arm System is specifically designed for Wrangler owners who want a complete system, bolt-in installation, and 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" comes from the inclusion of 2 non-adjustable control arms with our 100% Service Free Adventure Series joints installed at each end. Our industry leading, Adventure series mid-Arms feature 35 degrees of misalignment when paired with our Adventure series Joints at the frame connection and at the axle. The inherent bind in a factory JK control arm is greatly reduced. The arm is longer than the OEM control arm and allows you to correct the JK's caster up front. Driving you home with the most comfortable ride possible in a Wrangler, are our TRIPLE RATE coils. All 4 coils work together to achieve excellent on-road comfort that we feel is better than the OEM linear rate 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 JK 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.

When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, In tow, or down a Trail!  Thank you for considering Rock Krawler Suspension

 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 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 Drivesahft,Tom Woods,J.E. Reel)
