The Rock Krawler development team decided to design an off the shelf system for the JK Wrangler, tough enough to pre-run the toughest Off-Road races or help you build the baddest mall krawler on the planet, a suspension system that performs flawlessly off road without sacrificing on road handling.
The Rock Racer system was designed for speed. Both the bypass and coil-over shocks feature a remote reservoirs to minimize fade & maximize shock travel. The coil overs are a true dual rate setup with transition rings for height and cross over adjustment. The 3 tube bypass shocks are externally adjustable with (1) compression, (1) rebound and (1) free bleed lead screw. You can dial in the stance, ride, handling and performance you desire with simple adjustments.
The Rock Racer system transforms your JK into an off-road beast. Be sure read the Notes regarding this system to ensure you are ready to meet all the vehicle specific requirements for installation. This system is listed in our 5.5" segment for ease of listing. Typical lift heights are from 4.5" to 5.5".
