Rock Krawler | 18-22 Wrangler JL 2.5 Inch Adventure | Series 1 System

The Rock Krawler JL 3.5 X Factor Mid Arm System was designed for those who want a complete bolt-in installation, maximum articulation from a mid-arm kit and the durability and off-road performance you expect from Rock Krawler Suspension. The X Factor Series adjustable lower control arms offer a total of 90 degrees of misalignment that eliminates the bind found in your JL's factory lowers, while high misalignment adjustable upper control arms let you precision tune your JL's caster both front and rear.

Rock Krawler's industry leading triple rate coils give you 3.5 inch of lift to clear up to 40 inch tires, depending on model, and improve the on-road ride over the factory linear rate springs.

All Rock Krawler JL 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.
