Product Description
The WEHRLI CUSTOM FAB WCF100401 2011-2014 CHEVROLET 2500/3500HD 3/8 IN FRONT BUMPER SPACER KIT is a simple but extremely effective solution for correcting front bumper alignment issues on GM HD trucks. When installing aftermarket intercoolers, piping, grille conversions, or other front-end performance upgrades, the factory bumper can sometimes sit too close to the body or interfere with upgraded components.
This precision spacer kit moves the front bumper forward 3/8 inch, creating additional clearance while restoring proper body alignment. The result is improved fitment between the grille, bumper, and body lines while preventing contact with larger aftermarket components commonly used on modified Duramax trucks.
Manufactured from high-quality materials and designed specifically for the GM HD platform, the Wehrli spacer kit installs easily using factory mounting points and requires no cutting or modification. It is an excellent finishing touch for Duramax builds where proper panel alignment and clearance are critical.
