2001-2010 Duramax Engine Mount Kit (168030140)

Stock engine mounts fail over time as bushings deteriorate. This causes vibration and engine noise to become more pronounced. Degradation is accelerated in high-power engine applications. Engineered to anchor the engine and improve ride quality. The premium silicone bushings are designed to last the life of the vehicle, handle the high heat of the engine bay, and isolate vibration much better than polyurethane bushings.
