Rock Krawler JL35AXPLA-4TR 3.5 Inch Adventure-X Pro Trail Runner Long Arm Suspension System

The Rock Krawler JL35AXPLA-4TR is a 3.5-inch Adventure-X PRO Trail Runner Long Arm Suspension System engineered for the Jeep Wrangler JL 4-door. This system bridges the gap between a capable daily driver and a serious off-road rig, delivering exceptional geometry, ride quality, and trail performance in a single comprehensive package.

The Adventure-X architecture pairs a full high-clearance 4-link long arm front suspension with an independent 3-link long arm rear suspension. This combination optimizes handling geometry for both highway cruising and aggressive off-road articulation. The X2 rear suspension geometry features enhanced rear instant centers and roll centers for a smooth, controlled ride on any surface.

The Trail Runner designation identifies this system's coilover shock configuration, which adds an additional level of tunability over standard shock setups. Coilovers allow the owner to fine-tune ride height, damping, and overall handling characteristics to suit both street and trail demands.

PRO-level control arms mean this kit is equipped with four billet aluminum CNC-machined, service-free lower control arms at long arm length — providing maximum strength with zero grease maintenance. Each arm utilizes Rock Krawler's Adventure Series joint centers, which isolate road vibrations comparably to OEM bushings while offering high misalignment capability. A Teflon-lined inner sleeve ensures long-term durability without regular servicing.
