Rock Krawler 2018+ Jeep Wrangler JL 2DR 4.5in X Factor System - Stage 1

The Rock Krawler 4.5" X-Factor Mid-Arm System is designed for Sport and Sahara owners for a complete system, bolt-in installation, and excellent articulation. It features X-Factor Series adjustable upper and lower control arms with Pro-X Krawler Joints and Adventure Series joints, offering 95 degrees of misalignment and reducing inherent bind in factory JL control arms. The system allows precision tuning of the JL's caster and pinion angle. It includes TRIPLE-RATE coils for a comfortable on-road ride and proper free-length for off-road articulation, with correction pads to reduce spring bow. Front and rear track bar geometry corrections are included to center the axles. This system is upgradable to an RK Long-Arm System and includes a lifetime warranty.
