Rock Krawler 2021+ Jeep Wrangler JT (Diesel) 3in X Factor Pro (No Limits) Aluminum System

The Rock Krawler Suspension JT 3.0 inch X-Factor PRO "No-Limits" Mid-Arm System is designed for Rubicon owners seeking a complete, bolt-in system with superior articulation. All 8 control arms are crafted from solid 7075 aluminum and incorporate X-Factor benefits. The "No-Limits" designation comes from the inclusion of front sway bar links designed for the factory electronic sway bar disconnect feature in Rubicon Gladiator models. These sway bar links feature factory-sized hardware, a CNC machined billet aluminum center section, and Made in USA heim joints from FK bearing. The X-Factor Series adjustable upper and lower control arms, combined with Pro-X Krawler Joints and Adventure Series joints, offer 95 degrees of misalignment, significantly reducing bind in the factory JL/JT control arm. Maintenance-free "Adventure Series" joints are used at the frame connection, while "PRO Krawler Joints" connect to the axle. This adjustability allows for precise tuning of the JT's caster and pinion angle. The system includes TRIPLE RATE front coils and QUAD RATE rear coils for a comfortable on-road ride, which is considered an improvement over OEM linear rate springs. The coils are designed with the proper "Free-length" for off-road articulation and remain firmly seated (with appropriate shock length). Rock Krawler JL systems include correction pads to reduce spring bow, and track bar geometry corrections ensure centered axles for optimal on-road handling.
