    Product Description

    Brand new OEM replacement 6-rib (serpentine) drive belt for 1986-1987 Vin 7 Grand National, Turbo Regal, and 1987 GNX.  This drive belt is even BETTER than factory original featuring EPDM rubber construction which will not dry out or crack up as drive belts have in the past. This belt is the equivalent length of the factory original drive belt for stock vehicles with STOCK accessories/components and STOCK pulleys.

    Replaces the following GM belt numbers; GM #25525518, GM #10105307 and GM #88984193

    Please note, that if your vehicle has any aftermarket components with NON-STOCK pulleys, this may affect the fitment.  We do not accept returns on drive belts.


    We have done EXTENSIVE TESTING on belts available from other sources.  We have found most aftermarket drive belts are too long and will cause issues. This belt sold by Highway Stars is the factory original belt length for an original stock replacement drive belt.


    This is the finest quality original length drive belt that we are aware of.
