This a custom made solid aluminum bushing set to replace your worn out factory bushings that mount the rear differential to the chassis. These replace the entire stock bushing - rubber and its surrounding steel sleeve. So you will either need to melt the rubber then cut out the outer sleeve of the stock bushing, or press the whole unit out. These replacements then press into the stock brackets.
We also offer replacement rear diff moutning hardware listed separately. Mounting hardware is NOT included with the bushings.
Sold as a set of 4 to replace all 4 stock bushings.
