About this product

GM Genuine Parts Engine Mounts are designed, engineered, and tested to rigorous standards, and are backed by General Motors.

Engine mounts utilize rubber so that there is no direct metal-to-metal contact between the engine and the car body.GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
