Zone Offroad 11-19 Chevy/GMC 2500/3500 HD Torsion Bar Keys Leveling Kit

The Zone Offroad ZONC1204 is a 2-inch leveling kit designed for 2011-2019 Chevy/GMC 2500HD/3500HD 4WD models. This kit uses re-indexed torsion keys, cast in the USA and tested using resonant frequency technology, to achieve the desired front lift.
The torsion bar hex is CNC machined with round corners to minimize stress and maximize strength, providing 2 inches of lift with factory adjustment bolts. Installation is estimated at one hour using the appropriate torsion bar unloading tool. Longer shocks or Zone Offroad shock extensions are required.
This kit allows for 35x12.50 tires on stock wheels with minor trimming, but 33-inch tires are recommended for aftermarket wheels with less backspacing.
