Description
The Rock Krawler JT 4.5 X Factor "No Limits" Mid Arm System was specifically designed for Rubicon drivers 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 "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. Rock Krawler’s industry leading triple rate coils give you 4.5 inches of lift and improves the on-road ride over the factory linear rate springs.
