Rock Krawler Suspension JK45AXM-4 4.5 Inch Adventure X Mid-Arm Suspension System

The Rock Krawler Suspension JK45AXM-4 is a complete 4.5-inch Adventure X Mid-Arm suspension lift system engineered specifically for Jeep Wrangler JK 4-door models. This comprehensive bolt-in system delivers exceptional off-road articulation while maintaining superior on-road comfort for both daily driving and hardcore trail use.

Adventure Series Control Arms:

The Adventure X designation comes from the inclusion of 8 adjustable control arms equipped with 100% maintenance-free Adventure Series joints. These industry-leading mid-arms feature adjustable upper and lower control arms that offer a total of 70 degrees of misalignment when paired with Adventure Series joints at both the frame connection and axle. This design dramatically reduces the inherent bind found in factory JK control arms and allows you to precision-tune caster and pinion angles front and rear for optimal performance.

Triple-Rate Coil Springs:

All four triple-rate coil springs work together to achieve excellent on-road comfort that exceeds OEM linear-rate springs. The coils are built with proper free-length for maximum off-road articulation and remain firmly seated in the coil bucket when properly matched shocks are installed. They provide controlled reaction to bumps, rocks, sand, mud, and any terrain you encounter.

Geometry Correction Components:

All Rock Krawler JK systems include correction pads that reduce the spring bow inherent in the factory setup. The provided track bar geometry corrections, both front and rear, perfectly center the axles to ensure no compromise in on-road handling. This complete system provides the foundation for every adventure, whether on the street, in tow, or down the trail.
