The Prothane front frame shackle bushings for 1971–1991 GM applications are replacement parts to support the front frame shackle and keep spring alignment for older GM trucks and vans. Finished in black for a subdued look, they serve as serviceable components when restoring suspension fitment. Provided as direct-fit replacements, they match 1971–1991 GM front frame shackle requirements.
