2011-2016 Duramax Merchant Automotive 10550 High Performance Motor Mounts

Let's be honest, the factory motor mounts on your Duramax leave a lot left to be desired. They crack, break, and ultimately lead to improper driveline angles and increased vibration. Merchant Auto's motor mounts are made in the USA with high-strength steel and performance polyurethane bushings to offer your engine long-term support that will hold up under high horsepower applications. Each item includes hardware and threadlocker for installation. 

From MA: "Being a performance product that was built with strength and capability in mind, a more pronounced vibration at a stop or while idling may be present over the stock mounts due to the nature of their solid design. This is normal and will smooth out while driving."
