Silence engine shudder and keep the powertrain planted with the Pioneer Automotive Industries Engine Mount 612943 — a direct-fit Buick Riviera engine mount that also replaces the original unit on the 1988-1991 Buick Reatta, 1987-1991 Buick Riviera, and 1987-1991 Oldsmobile Toronado. Cataloged for the front / front-right position, this mount helps support and locate the engine while its bonded rubber isolator absorbs vibration so it doesn't reach the chassis and cabin.
Sure-Fit System: validated on vehicle-specific fixtures for a hassle-free, exact-fit installation.
Bonded rubber isolator: a blended rubber compound is bonded to the housing and tuned to each application for proper vibration absorption.
Durable housing: built from high-grade metal with a corrosion-resistant coating, or cast aluminum, depending on the application — with hydraulic fill and electronic control where the application specifies.
No-compromise replacement: a premium, exact-fit replacement part engineered for the listed vehicles.
If a worn or separated engine mount is behind vibration at idle or a clunk on acceleration, shifting, or deceleration, this replaces it.
Interchange: 2943
