1.5 Inch Block & U-bolt Kit | Chevy Silverado 2500 Hd 2wd/4wd (2001-2010)

Built for Silverado 2500 HD owners who want to level out rear sag and maximize tire clearance, this 1.5-inch block and U-bolt kit restores your truck's stance and handles heavier loads. Rough Country's tapered blocks reduce driveline angles while their heavy-duty construction outlasts factory cast options — pair with 32- to 33-inch tires for the ideal setup.
