Passenger Side Engine Mount – GM (85579395)

Passenger Side Engine Mount locates the engine, transmission or subframe and isolates vibration from the body. Rubber hardness and internal voiding are tuned to a specific powertrain, so a stiffer or softer substitute changes how much noise reaches the cabin.

Replace the Side Engine Mount when engine movement is visible when the throttle is blipped, when a clunk appears on take-up, or when the rubber has separated from the metal. Replacing one worn mount often shows up the next one.

For this Side Engine Mount the reference is 85579395, in our Engine Mounts & Covers range. Compare it with the number on the part you are replacing rather than with a photograph.

Genuine GM supplied for this Side Engine Mount, with the engineering number unchanged from the factory reference stamped on the original.

Position matters here: this is the passenger (right-hand) unit, and fitting it to the other side will not work.
