JL 392 Only
Product Resources
Features & Product Details
The Rock Krawler JL 3.5 X-Factor "No-Limits" Mid Arm System was designed with the 392 in mind and for those who want an easy bolt-in installation, excellent on-road ride and the durability and the off-road performance you expect from Rock Krawler Suspension. The No Limits front sway bar links allow Rubicon owners to use the factory sway bar disconnect function and still achieve maximum articulation.
The X Factor Series adjustable lower control arms offer a total of 90 degrees of misalignment that drastically reduces the bind inherent in JL 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 inches 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.

*If building with a spare delete we recommend dropping 1” in coil lift height for the rear.
*If building an overland or heavily upfitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
