A pair of cast iron torsion bar keys are at the heart of this 2" leveling kit that delivers a leveled stance, comfortable ride and handling and clearance for up to 35" tires. Specially engineered to allow re-use of factory shocks with the supplied upper shock extensions, this kit provides more suspension travel without inducing worry of overextending at full droop.
