Rock Krawler X-Factor No Limits Mid Arm Suspension Lift Kits
Rock Krawler X Factor No Limits mid-arm suspension lift kits are 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 for less binding. Rock Krawler's industry-leading triple rate coils give you plenty of lift and improve the on-road ride over the factory linear rate springs. All Rock Krawler systems include two rear spring seats, as well as the corresponding two front spring pads. 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. Tackle the trails and the streets with a Rock Krawler X Factor No Limits mid-arm suspension lift kit.
