The Prothane rear sway bar bushing set for 1981–1991 GM dually trucks (1 1/16in, red) is a direct replacement for the rear sway bar mounts on dual-rear-wheel models. These bushings restore correct sway bar seating and reduce unwanted movement compared with deteriorated originals. Verify your GM dually model and years to ensure proper fitment before ordering.
