Rock Krawler JL35AX2LA-4DTR 3.5 Inch Adventure-X2 Trail Runner Long Arm Suspension System

The Rock Krawler 3.5 Inch Adventure-X2 Trail Runner Long Arm Suspension System is a premium lift and suspension upgrade engineered for the 4-door Jeep Wrangler JL. Delivering a 3.5-inch lift with a purpose-built long arm geometry, this system is designed to excel equally on the daily commute and the most demanding off-road trails.

Adventure-X2 Long Arm Architecture:

• Full high-clearance 4-link front suspension combined with a high-clearance independent 3-link rear suspension for maximum articulation and precise on-road control
• X2 rear suspension geometry with enhanced rear instant centers and roll centers for a smooth, stable ride on highway and trail
• High clearance axle mounts provide increased ground clearance under the rear axle compared to stock
• Rear upper shock relocation brackets preserve full shock and suspension travel
• Service-free Adventure Series joints — 8 fully adjustable control arms with maintenance-free joints, no greasing required
• Trail Runner coilover shock package featuring Rock Krawler's RRD 2 5/8-inch remote reservoir racing coilovers, fully adjustable and tunable for on- and off-road performance

Triple-Rate Coil Springs:

• All 4 coils work in concert to deliver on-road comfort that exceeds OEM linear rate springs
• Built with proper free-length for off-road articulation, staying firmly seated in the coil bucket
• Provides controlled, progressive response to bumps, rocks, sand, mud, and varied terrain
• Includes Rock Krawler JL-specific correction pads to reduce factory spring bow

Geometry Corrections Included:

• Front and rear track bar geometry correction brackets to precisely center both axles
• Engineered to maintain stock-like on-highway handling characteristics after installation

The Adventure-X2 Trail Runner system is a complete bolt-in solution designed to support 35–40-inch tires, improve approach and departure angles, and serve as the foundation for any adventure — street, tow, or trail.
