Description

The Wehrli Custom Fabrication 100170 L5P Duramax HD Engine Swap Mounts are designed to facilitate the installation of an L5P 6.6L Duramax Diesel engine into 2001-2010 GM 2500 / 3500 HD Chassis (Chevrolet Silverado and GMC Sierra). These mounts are built for high-performance applications, effectively reducing engine flex and addressing common failure points found in OEM mounts.

Crafted from laser-cut, CNC-bent, and welded steel, these mounts feature a durable semi-gloss black powder coat finish for superior corrosion resistance. They are equipped with high-performance polyurethane bushings, which are known to enhance durability and provide a more rigid connection compared to factory rubber bushings. High-grade hardware is included for a secure installation.

These mounts precisely position the L5P Duramax engine block in the exact location of prior generation Duramax engines that were originally fitted to the 2001-2010 GM HD trucks. It is important to note that while these mounts enable the swap, the overall installation process for an L5P Duramax into an older chassis is extensive and requires significant modifications to the transmission, drivetrain, electronics, fuel, exhaust, and cooling systems. The product is intended for high-performance use only, and users should anticipate an increase in engine vibration and noise after installation. It is specifically designed for use in 2001-2010 GM HD Truck Chassis ONLY.
