Rock Krawler 4.5in T-Rex 'No Limits' Trail Runner Long Arm Lift Kit

The Rock Krawler 4.5 T-Rex No Limits Trail Runner Systems are for those JL 2 Door Owners looking to get the best off road ability without modifying the fuel system. The Rock Krawler No Limits systems feature our No limits front sway bar links that allow Rubicon owners to utilize the factory Rubicon sway bar disconnect feature and still achieve full articulation. It features a X Factor mid arm front suspension system combined with a X Factor long arm rear system. The rear system provides the tried and true independent 3 link conversion with X2 rear suspension geometry. New high clearance axle mounts provide 4.5 inches of ground clearance under the rear axle as compared to stock. Rear upper shock relocation brackets ensure you do not lose any shock travel. The combination of high clearance mid arm front suspension and high clearance rear long arm suspension makes your 2 Door JL tough to beat on the trails. And if the day ever comes where you want to modify the fuel system and go full long arm suspension, you have that option.
