Product Description
The WEHRLI CUSTOM FAB WCF100446 3/8IN BUMPER SPACER KIT is a simple but highly effective solution designed to provide additional clearance between the front bumper and core support on 2020+ GM Silverado and Sierra 2500HD / 3500HD Duramax trucks. When installing large intercooler piping, aftermarket turbo systems, or upgraded performance components, factory bumper positioning can sometimes create interference. This spacer kit allows you to move the bumper forward slightly, creating the extra room required for proper fitment.
Manufactured by Wehrli Custom Fabrication, the kit includes precision-machined spacers and hardware designed to maintain proper bumper alignment while providing approximately 3/8 inch of forward spacing. Installation is straightforward and can typically be completed in under an hour with basic hand tools. This small adjustment can make a major difference when installing performance parts on modern L5P Duramax trucks.
