The Prothane control arm bushing kit in black for 1965–1970 GM full‑size rear applications replaces upper and lower control arm bushings to restore proper suspension fit and function. These direct‑replacement bushings help maintain alignment and reduce play at the rear control arms without requiring modifications to original mounting points, making them a practical restoration component.
