Tuff Country 97021 1" Lift Block & U-Bolt Kit

The Tuff Country 97021 1" Lift Block & U-Bolt Kit is designed to provide your GM Silverado/Sierra 2500HD 4WD with 1-inch of rear lift. This bolt-on raises the rear by 1 inch while preserving a factory-like ride, making it ideal for towing, hauling, or achieving a balanced stance.
