This item ships for free! (Continental U.S. only)

The TeraFlex JK 4dr: 4” Suspension System w/ 8 Short Control Arms & Front Track Bar delivers the necessary components to lift your rig to conquer the most extreme trails and conditions. Features a complete set of adjustable Short Control Arms, HD Forged Adjustable Front Track Bar, and rear track bar bracket to optimize geometry. An adjustable rear track bar is recommended.

Every TeraFlex suspension system is engineered with drivability and performance in mind. Properly developed suspension geometry, roll center, and load tuning ensures that all factory stability controls remain functional and within the parameters that Jeep originally engineered into the vehicle.

Not only do TeraFlex kits drive straight, but they will crawl over anything to get you there and back!

Does NOT include shocks. We recommend Falcon Performance Shocks or TeraFlex 9550 VSS Twin-Tube Shocks. These are the only shock absorbers engineered to work with TeraFlex lift coil springs to improve both compression and rebound for optimal vehicle stability. Shocks are available separately.
