Rock Krawler X-Factor Stage 1 Mid-Arm Suspension Lift Kits
Rock Krawler X Factor Stage 1 mid-arm lift kits are designed for those who want a complete bolt-in installation, maximum articulation from a mid-arm kit, along with 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 Jeep's factory lowers, while high misalignment adjustable upper control arms let you precision tune your Jeep's caster both front and rear.
Rock Krawler's industry leading triple rate coils and multi-rate coil springs give you the added lift to clear larger tires and improve the on-road ride over the factory linear rate springs. The kits are upgradeable to other Rock Krawler systems and are offered in a wide range of lift heights for many Jeep models. For improved off-road ability, an excellent highway ride, and a hassle-free install, order the Rock Krawler X Factor Stage 1 system preferred for your Jeep.
