Product Description
The WEHRLI CUSTOM FAB WCF100462 3/4" BUMPER SPACER KIT is a simple yet essential upgrade for 2015-2019 GM Duramax trucks running aftermarket turbo systems, larger intercooler piping, or performance intake upgrades. Designed by Wehrli Custom Fabrication, this precision spacer kit relocates the factory bumper forward by approximately 3/4 inch, providing additional clearance for performance components while maintaining factory alignment and appearance.
Many Duramax performance upgrades such as larger turbo kits, high-flow intercooler piping, or custom fabricated intake systems can create tight clearance issues with the factory bumper location. The Wehrli bumper spacer kit solves this problem cleanly with CNC-machined spacers and high-strength hardware designed for quick installation and long-term durability.
