Rock Krawler JK35AXM-2B51 3.5" Adventure X Mid-Arm Suspension Lift System with Bilstein 5100 Shocks

The Rock Krawler JK35AXM-2B51 is a complete 3.5-inch Adventure X Mid-Arm suspension lift system paired with Bilstein 5100 shocks, purpose-built for the 2-door Jeep Wrangler JK platform. Engineered as a comprehensive bolt-in solution, this system delivers the best articulation available in a mid-arm lift kit while maintaining excellent on-road drivability.

The "Adventure X" designation refers to the inclusion of 8 fully adjustable control arms equipped with Rock Krawler's 100% service-free Adventure Series joints. These industry-leading mid-arms offer a total of 70 degrees of misalignment when paired with Adventure Series joints at both the frame connection and axle end — dramatically reducing the inherent bind found in factory JK control arms. The fully adjustable upper and lower arms allow for precision tuning of caster and pinion angle at all four corners.

The system rides on Rock Krawler's signature tuned Triple Rate coil springs, with all four coils working in concert to deliver on-road comfort that surpasses OEM linear-rate springs. The springs are built with the correct free-length for maximum off-road articulation and remain firmly seated in the coil bucket throughout the suspension's travel range. Spring correction seats are also included to eliminate the spring bow inherent in the factory setup and correct vehicle lean.
