Once cast in the USA, Zone Offroad uses resonant frequency technology to guarantee a solid casting. The torsion bar hex is CNC machined with round corners for reduced stress concentration and to provide the most possible strength while yielding 2” of lift with the adjustment bolts in the factory setting.
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 35x12.50 tires mounted on stock wheels with only minor trimming, but if aftermarket wheels with less backspacing are used, then a 33” tire is recommend.
