Rock Krawler Adventure Series Mid Arm Stage 1 Suspension Lift Kits

The Rock Krawler Adventure Series Mid Arm Stage 1 suspension lift kits are designed for those who want an easy bolt-in installation, excellent on-road ride and the durability and the off-road performance you expect from Rock Krawler Suspension. These kits feature Rock Krawler's service free control arm joints that utilize innovative technology to provide the best possible ride. The Adventure Series fixed lower control arms offer a total of 70 degrees of misalignment that greatly reduces the bind inherent in factory lowers; while the triple rate coils give you additional tire clearance for larger size tires and improves the on-road ride over the factory linear rate springs. All Rock Krawler Adventure Series systems include correction pads to help minimize spring bow inherent in the factory setup. The provided track bar geometry corrections—both front and rear—let you perfectly center the axles so there's no compromise in road handling.

System features and benefits:

* Complete bolt-in system
* Excellent highway ride
* Improved off-road ability
* Triple rate coil springs
* Rear spring leveling pads
* Upgradeable to Rock Krawler long arm
* Service free control arm joint package
* Jeep models remain level on all 4 corners
* Manufacturer lifetime warranty on all hard parts
