      Description

      Premium Suspension Lift. The Rock Krawler 4.50-Inch Trail Runner Stage 2 Long Arm Suspension Lift Kit with Coilovers significantly enhances your Jeep YJ’s off-road capability and street handling. By stretching the wheelbase to 102 inches using front and rear extensions, it improves approach and departure angles. The system combines an independent multi-link front suspension with a triangulated four-link rear and sport-tuned coilovers for superior ride quality and handling across varied terrain.

      Construction and Appearance. This kit features heavy-duty components such as 2" OD lower control arms constructed from 7/16" wall DOM steel tubing, complemented by laser-cut .25" thick steel crossmembers and skid plates. The coilovers are 2.625" RRD remote reservoir racing units with 14" travel, fully adjustable and integrated into the frame, providing a durable, race-inspired finish optimized for rugged off-road use.

      Installation. Installation requires advanced fabrication skills as welding and custom modifications, including fabricating an engine hoop support, are mandatory. Additional supporting components such as a custom cat-back exhaust and rear fuel tank conversion are necessary, making this a complex kit best suited for experienced installers knowledgeable in suspension setups.

      Application. Designed specifically for Jeep Wrangler YJ models from 1987 to 1995, this kit requires specific wheel widths and backspacing, rear fuel tank conversions, and fitment considerations like flat or high line front fenders and stretch rear corners. Steering geometry components are sold separately to accommodate axle configuration and ensure optimal performance.
