Product Details

Important Notes:

  • All lift heights based on Rubicon Models
  • Rock Krawler recommends a new front C.V. driveshaft for all front shocks with max. extended length greater than 29"
  • Tire Size: 37" to 40" depending on model (contact us for further details)


The Rock Krawler JL 3.5 Max Travel System was designed for those who want a complete bolt-in installation, increased articulation 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 in your JL's factory lowers, while high misalignment adjustable upper control arms let you precision tune your JL's caster. Rock Krawler's industry leading triple rate coils give you 3.5" of lift to clear up to 40" 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.
