TRANSMISSION CROSSMEMBER UPGRADED BLACK POLY BUSHINGS (4) SET
These are factory-style replacement crossmember black poly bushings, complete with new hardware. The polyurethane material is far stronger and tougher than the factory GM rubber bushings. The GM bushings are no longer available.
These four black poly bushings sandwich the factory transmission crossmember at the ends to each side of the frame rail. Unlike the factory original bushings, these have a metal insert.
Each kit comes with four zinc-plated grade 10.9 bolts, two zinc-plated steel brackets and four black poly isolators, which will do both ends of the factory crossmember brace.
The four new grade 10.9 bolts and metal bracket are zinc plated to prevent rust.
Because of age, exposure and weather, the original GM rubber bushings can become compressed and deteriorate. They can also retain moisture and cause the ends of the crossmember to rust out. If these bushings in your car are severely compressed, it can alter the angle of the transmission in relationship to the rear.
NOTE - Our top photo shows the 10 items in this set. The lower left photo shows the passenger’s side where the bushing meets the transmission crossmember secured to the frame. The lower right photo shows the driver’s side where the bushing meets the transmission crossmember secured to the frame.
An excellent time to replace these bushings is when you are having the transmission rebuilt. (You do not have to remove the transmission to install these, however you do have to support the transmission in order to remove and reinstall these new bushings.)
This is just another item that should be replaced to retain a firm support for the transmission. You may also want to replace the Rear Transmission Mount, Part #6941, at the same time. You may also want to replace #6891 Engine Mounts or #6941 Rear Transmission Mount. Related part - #7889 Stainless Steel Transmission Cooling Line Kit (4 pieces)
Another good restoration item.
