The Rock Krawler JL 4.5 X Factor Mid Arm System is a complete bolt-in suspension kit designed for maximum articulation and off-road performance for the Jeep JL. It features adjustable lower control arms with 90 degrees of misalignment to eliminate bind, and high misalignment adjustable upper control arms for precise caster tuning. The system includes Rock Krawler's triple-rate coil springs providing 4.5 inches of lift, allowing for clearance of up to 40-inch tires depending on the model and fender setup. It also incorporates correction pads to reduce spring bow and front and rear track bar geometry corrections for proper axle centering and improved on-road handling. The system offers an excellent highway ride and improved off-road capability. It is backed by a lifetime warranty on all hard parts and is upgradeable to a Rock Krawler JL Long Arm system.
