Rock Krawler 2020+ Jeep Wrangler JLU 4DR (Diesel) 3.5in Ultimate AdventureSystem - Stage 1

The Rock Krawler JL 3.5 Ultimate Adventure Mid Arm System is engineered for straightforward bolt-in installation, delivering an exceptional on-road ride combined with the robust durability and off-road prowess characteristic of Rock Krawler Suspension. This kit incorporates Rock Krawler’s acclaimed, maintenance-free control arm joints, recognized as industry leaders for optimizing ride quality in the Jeep Wrangler. The Adventure Series fixed lower control arms allow for 70 degrees of misalignment, significantly mitigating the bind often encountered with factory JL lower control arms. High-misalignment adjustable upper control arms facilitate precise tuning of the front caster and rear pinion angle. Rock Krawler’s innovative triple-rate coil springs provide a 3.5-inch lift, enabling clearance for up to 40-inch tires (model dependent), and notably enhance on-road ride comfort compared to the factory linear-rate springs. All Rock Krawler JL systems include correction pads designed to minimize the inherent spring bow in the factory setup. Comprehensive front and rear track bar geometry corrections are provided to perfectly center the axles, ensuring uncompromised handling.
