Wehrli 01-10 GM HD Chassis L5P Engine Swap Mount Kit - Semi-Gloss Black

When you're swapping a newer L5P Duramax engine into an earlier 2001-2010 GM HD truck chassis, you need mounts that can handle the job. This kit from Wehrli Custom Fabrication includes the left and right side L5P swap mounts, specifically designed to position the L5P engine block precisely where the older generation Duramax engines sat in these trucks. It’s a well-built solution for performance applications, ensuring your powerful new engine stays securely in place.

These mounts are constructed from laser-cut, CNC-bent steel for a solid foundation, then welded for maximum strength. They incorporate high-grade hardware and durable polyurethane bushings, which are key to reducing engine flex and addressing common failure points found in stock mounts on these older trucks. Wehrli has torture-tested these mounts in-house on high-horsepower builds, so you can trust they’ll hold up under demanding conditions. The semi-gloss black powder coat finish not only looks clean, giving an OEM-plus appearance, but also adds improved corrosion resistance for longevity.

This kit is designed for the 2001-2010 GM HD truck chassis and is essential for preventing excessive engine and driveline deflection, especially in high-horsepower applications. It’s a critical component for a successful and reliable engine swap, giving you enhanced performance and a more solid feel from your build.
