Product Description
Brand-new discontinued GM/ACDelco rear spring polyurethane isolator mounting bushing (1) for 1984-1987 Buick Grand National, Turbo Regal, and 1987 GNX with stock rear springs.
The factory original rubber isolator mounting bushings are commonly cracked-up and/or dried out on older vehicles and should always be replaced when re-installing or replacing rear coil springs.
There are two of these bushings used per car. Each spring uses only one isolator bushing which goes between the top of the spring and the body (there is no bushing used between the bottom of the spring and the chassis).
These genuine GM/ACDelco parts were purchased in bulk boxes and will ship rebagged.
Note: Although we sell these parts individually, it is proper service procedure to replace these bushings in pairs.
