Use this leveling kit to level the front of your Chevy/GMC 1500 Silverado 4x4 with Tuff Country EZ-Ride Suspension's torsion bar keys. These torsion bar keys are easy to install and are made to level trucks equipped with factory torsion bars. The way the leveling kit works is by reindexing the factory torsion bars, which will level the suspension of your truck without "cranking up" the stock torsion bars.
