Rock Krawler JL35AXPLA-4D 3.5 Inch Adventure-X Pro Long Arm Suspension Lift Kit

The Rock Krawler JL35AXPLA-4D is a 3.5-inch Adventure-X Pro long arm suspension system engineered to deliver the ideal balance between daily street driving and serious off-road performance. Purpose-built for the 4-door Jeep Wrangler JL platform, this full long arm system fundamentally transforms suspension geometry for dramatically improved articulation, ride quality, and ground clearance over stock.

At the heart of the Adventure-X Pro system is Rock Krawler's high clearance dual-link architecture. The front utilizes a full high clearance 4-link long arm configuration, while the rear features an independent high clearance 3-link long arm setup. This combination optimizes both instant centers and roll centers for a smoother, more controlled ride on-road and maximum flex capability off-road.

PRO-Level CNC Billet Aluminum Control Arms:

• 4 billet aluminum CNC-machined lower control arms in long arm length — providing exceptional strength with zero maintenance requirements
• Service-free Adventure Series joint centers in every control arm — isolate harsh road vibrations, feature high misalignment capability, and use a Teflon-lined inner sleeve that rotates freely to prevent bushing wear or deformation through mud, sand, salt, snow, and dirt
• Steel sleeve design accepts the mounting bolt and acts as a buffer against bracket clamping forces — extending joint life significantly

Suspension System Features:

• 3.5 inches of lift over factory ride height
• Triple-rate coil springs — all four coils work in concert to outperform OEM linear-rate springs for comfort during street driving, towing, and off-road use
• Coils built with the proper free-length for maximum off-road articulation while staying firmly seated in the coil bucket
• High clearance axle mounts add up to 3.5 inches of ground clearance under the rear axle compared to stock
• Rear upper shock relocation brackets preserve full shock and suspension travel after installation
• Geometry correction pads included to reduce the spring bow inherent in the factory JL suspension setup

The Adventure-X Pro long arm system is designed to be a comprehensive, high-performance solution — equally capable as a street commuter, a tow rig, or a trail machine. A professional alignment by a technician with off-road experience is recommended following installation.
