Does it feel like your 6.6L Duramax is not as smooth as it used to be? Do you feel like it is vibrating more than usual? It may be your engine mounts. Overtime, the factoy engine mounts can deteriorate causing more vibration and engine noise. Solve this issue with a set of PPE High Performance Engine Mounts.
These engine mounts are designed to secure the engine and improve overall ride quality. The bushings used are constructed of premium silicon and are designed to last the life of the vehicle. They will also not be affected by engine heat and are much more resilient than polyurethane style bushings.
These engine mounts are available in four different hardness options: 40A = softest to 70A = firmest. The 50A is closest to OEM firmness.
