Passenger Side Engine Mount – GM (84160829)

Passenger Side Engine Mount is a compliant mounting element that holds a drivetrain component in place while absorbing movement. The bonded rubber fails from heat and oil long before the metal does.

Replace the Side Engine Mount when the bonded rubber is cracked, when fluid has leaked from a hydraulic mount, or when vibration at idle has increased. Check the other mounts before deciding how many to change.

This Side Engine Mount is listed as part 84160829 (Engine Mounts & Covers). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is GM dealer-sourced stock rather than an equivalent, so the number on the Side Engine Mount traces straight back to the manufacturer.

This listing is specifically for the passenger (right-hand) side; the opposite side is a separate part number.
