Product Details

2015-2019 Silverado and Sierra 2500HD / 3500HD CNC machined billet aluminum spacer kits from WCFab move the front bumper forward, keeping it off the frame horns 3/8 of an inch while maintaining the maximum mounting surface area for structural integrity. Moving the bumper forward allows for the fitment of wider and taller wheel and tire combinations with a more negative offset. It prevents or reduces the need for additional trimming of OEM components. - - Finished in a Flat Black powder coat for additional corrosion resistance and OEM-like appearance. - - Installs easily with basic hand tools. - - For more aggressive fitments, please see our 3/4" Spacer Kit part number WCF100462
