- 2007 to 2016 JK Wrangler Unlimited and Rubicon Unlimited (4-door models)
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.
