Wehrli Custom Fab Engine Mounts 17-26 GM 6.6L Duramax L5P
Description
Pumping more power into an already powerful Duramax engine gets you the torque and horsepower you want but adds stress onto every part that it's connected to. Plus, if your engine mounts aren't upgraded it can rob you of power transfer and throttle response.
Upgrade the strength and reliability of your drivetrain with the WCFab 2017-2026 L5P Duramax HD Engine Mounts. Designed specifically for GM 2500HD and 3500HD trucks equipped with the 6.6L L5P Duramax, these heavy-duty mounts provide superior engine stability over factory components—especially in high-performance and towing applications.
Whether you're pushing higher horsepower, towing heavy loads, or simply replacing worn OEM mounts, these HD engine mounts are engineered to minimize engine movement, reduce driveline stress, and improve overall durability.
Built for Performance & Reliability
Factory engine mounts are known to wear out or fail under increased torque and demanding conditions. These WCFab HD mounts are designed to handle the added stress of tuned and modified L5P Duramax engines, helping to prevent excessive engine movement and potential drivetrain damage.
The integrated polyurethane bushings offer a balance of rigidity and vibration control, giving you improved engine stability without sacrificing daily drivability.
