Rock Krawler JL35AX2LA-4TR 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 coilover-equipped lift kit engineered to bridge the gap between confident daily driving and serious off-road performance. Designed for the Jeep Wrangler JL 4-Door, this system delivers a full 3.5 inches of lift with dramatically improved geometry, articulation, and on-road composure compared to the factory setup.

At the heart of the Adventure-X2 system is a full high clearance 4-link long arm front suspension paired with a high clearance independent 3-link rear long arm suspension—Rock Krawler's signature layout that maximizes axle articulation while preserving predictable street handling. The X2 rear geometry features enhanced rear instant centers and rear roll centers for a noticeably smoother ride on- and off-road.

The Trail Runner designation means this system is equipped with 2.625-inch RRD Racing Coilover shocks front and rear, replacing the factory coil spring setup for a fully tunable, high-travel platform. Coilovers provide an additional level of adjustability to dial in ride height, damping, and off-road performance to your preference.

Key Features:

• 3.5-inch lift for increased ground clearance and larger tire fitment
• Full high clearance 4-link long arm front suspension for improved caster, anti-dive, and articulation
• High clearance independent 3-link rear long arm suspension with X2 geometry for enhanced rear instant and roll centers
• 2.625-inch RRD Racing Coilover shocks front and rear for a fully tunable, high-travel setup
• High clearance axle mounts provide 3.5 inches of additional ground clearance under the rear axle compared to stock
• Rear upper shock relocation brackets preserve maximum shock and suspension travel
• Service-free long arm joints eliminate grease points for reduced maintenance
• Correction pads included to reduce the spring bow inherent in the factory JL configuration
• Designed and manufactured in the USA

The Rock Krawler Adventure-X2 Trail Runner system is built for Wrangler owners who demand a suspension that performs equally well on the highway, during towing, and on the most demanding trails—without compromise.
