Rock Krawler JK35AX2LA-4 3.5 Inch Adventure-X2 Long Arm Suspension Lift Kit

The Rock Krawler JK35AX2LA-4 is a 3.5-inch Adventure-X2 Long-Arm Suspension System engineered to strike the ideal balance between daily street driving and serious off-road performance. This complete long-arm lift kit delivers full high-clearance geometry front and rear, transforming the way your Wrangler handles both pavement and the trail.

Advanced Suspension Architecture:

• Full high-clearance 4-link long-arm front suspension paired with a high-clearance independent 3-link rear long-arm suspension for maximum articulation and control
• X2 rear suspension geometry features enhanced rear instant centers and rear roll centers for the smoothest riding 3-link suspension available
• High-clearance axle mounts provide 3.5 inches of additional ground clearance under the rear axle compared to stock
• Rear upper shock relocation brackets ensure no loss of shock travel or suspension travel
• Service-free long-arm joint system — no greasing required; joints are engineered so tightening the bracket clamps the sleeve rather than compressing the bushing, resulting in a long-lasting, noise-free design
• Heat Shield thermal barrier protection on front control arm joints at the frame, mirroring OEM-level protection
• Triple-rate coil springs deliver exceptional on-road comfort that surpasses factory linear-rate springs while maintaining proper free-length for off-road articulation
• Correction pads included to minimize factory spring bow inherent in the JK platform
• Track bar geometry corrections, both front and rear, to properly center axles without compromising on-road handling
• Rear axle can be positioned up to 1 inch rearward of stock, perfectly centering it under typical aftermarket flat fenders

Installation Notes:

• Requires removal of OEM rear axle side brackets
• Requires welding of provided rear axle side control arm, shock, sway bar link bracket, track bar bracket, and rear axle truss
• Requires removal and welding of provided frame-side rear shock mount
• Minor exhaust rerouting required ahead of the collector on the driver's side — recommended prior to suspension installation
• Installing limiting straps after setup is strongly recommended to prevent over-extension of suspension components
• Recommended rim backspacing: 4.5 inches for 33–35-inch tires; 3.5 inches for 37-inch tires

The Rock Krawler Adventure-X2 long-arm system is designed and manufactured in the USA, delivering a comprehensive solution with proven geometry whether you're cruising on the highway, towing, or tackling demanding trails.
