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. This easy to install torsion bar key leveling kit is designed to lift the front of your Chevrolet Colorado or GMC Canyon 2 inches. The kit includes front shock spacers to not only compensate for the added lift, but gain wheel travel by allowing the suspension to fully droop to the factory frame limiter.
The rear is lifted with a pair of add-a-leafs for added capacity and reduced axle wrap. Differential Drop is included as well for proper alignment. Zone Offroad rear shocks are available in the accessories section.
