Zone Offroad torsion bar keys are made in the USA and are 100% resonant frequency tested to ensure a solid casting. Once tested the keys are CNC machined to ensure the proper amount of lift for your vehicle. These keys are designed lift the front of your truck 2 inches. Order Zone Offroad shock extensions with the keys unless longer shocks are installed with the kit.

With the correct torsion bar unloading tool, installation can be performed in one hour. Zone Offroad shock extensions are required with the torsion bar keys unless longer shocks are being installed. This kit will clear 33x12.50 tires mounted on stock wheels with only minor trimming, but if aftermarket wheels with less backspacing are used, then a 32 inch tire is recommend.
