2017-2025 L5P Duramax HD Engine Mounts

2017-2025 L5P Duramax Heavy Duty Engine Mounts developed and tested for use on high-horsepower applications to reduce engine flex in the chassis and broken OEM engine mounts.

These high-performance Duramax motor mounts have been designed to maintain the alignment features of OEM mounts while adding significant strength and durability by adding durable performance polyurethane bushings for years of trouble free operation. OEM Engine mounts notoriously separate under high-performance, high-load applications, which can lead to premature rear engine cover, transmission bellhousing, and other driveline failures. OEM mounts can also cause performance-robbing boost leaks when the engine can flex and disrupt or even fail the intercooler pipe connections to the intercooler.

Kit includes left and right Duramax engine mounts, high grade fasteners, and thread locker for installation.

NOT Recommended for daily-driven street trucks. These HD engine mounts create additional engine noise and vibrations due to their heavy-duty design and construction. Designed specifically for high-horsepower, high-performance applications where OEM engine mounts fail due to increased engine torque.
