About this product

GM Genuine Parts Engine Mounts are designed, engineered, and tested to rigorous standards, and are backed by General Motors. When you start noticing a rough idle, harsh motor movements, or loud clunking noises during hard acceleration, it often points to a worn component that can no longer secure the motor firmly to the vehicle chassis. These replacement parts hold the engine securely to the body or engine cradle, absorbing normal powertrain vibrations and significantly reducing the shaking felt inside the cabin for a smoother, quieter ride. By keeping the engine properly positioned within the bay, they also help maintain correct driveline angles, keep drive and axle shafts aligned, and prevent dangerous shifting that can damage critical belts, hoses, and exhaust systems. Engineered to handle the heavy torque of daily stop-and-go traffic and withstand constant heat under the hood, these mounts are rigorously validated to function seamlessly with surrounding components to minimize interference and provide reliable stability. GM Genuine Parts are the true OE parts installed during the production or validated by General Motors for GM vehicles.
