Rock Krawler 2021+ Jeep Wrangler JT (Diesel) 3in X Factor Pro Aluminum Trail Runner System

The Rock Krawler Suspension JT 3.0 inch DIESEL X-Factor PRO Mid-Arm System is designed for Sport/Overland owners seeking a complete, bolt-in system with the best articulation of any mid-arm kit on the market. All 8 control arms are made from solid 7075 aluminum and include X-Factor benefits. The system offers durability and off-road performance. Adjustable upper and lower control arms (X-Factor Series) provide 95 degrees of misalignment when paired with Pro-X Krawler Joints and Adventure Series joints, reducing bind in the factory JL/JT control arm. Rock Krawler maintenance-free "Adventure Series" joints are at the frame connection, and "PRO Krawler Joints" are at the axle connections. Adjustability allows for precision tuning of the JT's caster and pinion angle front and rear. TRIPLE RATE front coils and QUAD RATE rear coils provide a comfortable ride, better than OEM linear rate springs. The coils have the proper "Free-length" for off-road articulation and stay seated in the coil bucket (with proper length shocks). The system includes correction pads to reduce spring bow, and track bar geometry corrections (front and rear) to perfectly center the axles, improving on-road handling.
