Rock Krawler Suspension JL45AXM-4XE 4.5 Inch Adventure X Mid-Arm Suspension Lift System for Jeep JL 4XE

The Rock Krawler Suspension JL45AXM-4XE is a 4.5 inch Adventure-X Mid-Arm System specifically designed for Jeep Wrangler JL 4XE Sport and Sahara owners who want a complete system with bolt-in installation and exceptional articulation. This system delivers proven durability and off-road performance for both street and trail driving.

Advanced Control Arm Design:

The Adventure-X designation comes from the inclusion of 8 adjustable control arms with 100% service-free Adventure Series joints installed. These industry-leading Adventure-X mid-arms feature adjustable upper and lower control arms offering a total of 70 degrees of misalignment when paired with Adventure Series joints at both frame and axle connections. This adjustability allows you to precision tune caster and pinion angles front and rear.

Triple Rate Coil Spring System:

The system features triple rate coils that work together to achieve excellent on-road comfort superior to OEM linear rate springs. The coils are built with proper free-length for off-road articulation, remain firmly seated in the coil bucket, and provide controlled reaction to bumps, rocks, sand, and mud.

Geometry Corrections:

All Rock Krawler JL systems include correction pads that reduce the spring bow inherent in factory setups. The provided track bar geometry corrections for both front and rear allow perfect axle centering without compromising on-road handling.

This comprehensive suspension system provides the foundation for street driving, towing, or trail adventures with the Jeep Wrangler JL 4XE platform.
