18C WRANGLER JLU 4DOOR3.5IN ULTIMATE ADVENTURE SYSTEM B51

The Rock Krawler 3.5 Ultimate Adventure Mid-Arm System is a complete bolt-in suspension system designed for Jeep Wrangler JLU (Gas Models) owners seeking excellent articulation and durability. It provides a comfortable on-road ride due to its Triple-Rate coils, which are designed to offer better comfort than OEM linear rate springs, maintain proper free-length for off-road articulation, and react in a controlled manner to various terrains. The system includes 4 non-adjustable lower control arms and 4 fully adjustable upper arms with 100% service-free Adventure Series joints, offering 70 degrees of misalignment. It also reduces the inherent bind in factory JLU control arms and includes front and rear track bar geometry corrections for perfect axle centering and improved on-road handling. Spring correction pads are included to reduce spring bow. The system is upgradable to an RK Long-arm System and comes with a lifetime warranty.
