    Product Description

    Brand-new pair (left and right sides) of "Made in USA" OEM (rubber isolator) motor mounts for 1984-1987 Buick Grand National, Turbo Regal, and 1987 GNX with 3.8 liter SFI turbo engine.

    If your application is not for a "race car", OEM rubber mounts are the widely preferred replacements. Only OEM rubber isolator mounts will stop most of the engine vibration from being transmitted into the frame and cabin of the vehicle.

    We have heard too many instances of unhappy Turbo Regal owners who had aftermarket polyurethane replacement motor mounts installed and then experienced obnoxious and unacceptable amounts of engine vibration when driving. Don't find out the hard way and make the same polyurethane mistake.

    These parts are direct replacements for original GM rubber engine mount part numbers 1258718 (RH) and 25504647 (LH).

      These are well built. Closest feel to OE that I’ve personally seen.
