Tuff Country 1-inch Rear Block & U-Bolt Kit for 2011-2023 Chevy Silverado 2500HD 4WD trucks. This rear suspension kit uses cast-iron lift blocks and application-specific extended zinc-plated U-bolts to add 1 inch of rear height.
This is a straightforward rear-height option for a Silverado 2500HD that sees daily highway miles, jobsite use, towing, or occasional dirt-road travel. Confirm your truck's year, 4WD configuration, and current suspension setup before installation.
