Features & Product Details

The Rock Krawler 3.5" X-Factor 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. This system proves its durability and off-road performance every time you hit the streets or trail! Rock Krawler's industry leading, X-Factor Series, adjustable upper and lower control arms, offer a total of 95 degrees of misalignment when paired with the Pro-X Krawler Joints and Adventure Series joints. The inherent bind in a factory JK control arm is greatly reduced. The maintenance free "Adventure Series" joints are found in your front and rear control arms at the frame connection, while the "PRO Krawler Joints" tie in your axle connections. With so much adjustability, it allows you to precision tune the JK's caster and pinion angle front and rear. Driving you home with the most comfortable ride possible in a Wrangler, are the 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, let you perfectly center the axles so there is no compromise in on road handling. When Rock Krawler designs a system, their 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 Driveshaft, Tom Woods, J.E. Reel)
