The Rock Krawler JK35AXPLA-4 is a 3.5-inch Adventure-X Pro Long-Arm suspension lift system engineered for the 4-door Jeep Wrangler JKU. Blending the demands of daily driving with hardcore trail performance, this complete long-arm system delivers exceptional geometry, ground clearance, and on-road refinement in a single comprehensive kit.
At the heart of the Adventure-X Pro system is the Adventure-X2 dual-suspension architecture, which combines a full high-clearance 4-link long-arm front suspension with an independent high-clearance 3-link long-arm rear suspension. Enhanced rear instant centers and rear roll centers make this one of the smoothest-riding 3-link setups available, delivering confident handling on the highway and aggressive capability on the trail.
The "PRO" designation signifies the inclusion of four billet aluminum CNC-machined, service-free lower control arms in long-arm length. These maintenance-free arms feature Rock Krawler's proprietary Adventure Series joint centers, which isolate road vibrations to OE bushing levels, accommodate high misalignment angles, and use a Teflon-lined inner sleeve for lasting durability — with no greasing ever required.
The X2 rear axle bracket system provides 3.5 inches of additional ground clearance under the rear axle compared to stock, while rear upper shock relocation brackets preserve full suspension travel. Weld-on long-arm mounting brackets with OEM-style weld scheduling and Heat Shield Products thermal barriers protect the front control arm joints at the frame.
