The BMR Xtreme Anti-Roll Bar for 1978–1987 GM G-Body is a solid 1.375-inch rear sway bar built for hard launches and drag-focused street use. It reduces body roll to transfer more power to the rear wheels while retaining usable street manners. Polyurethane bushings molded from 88‑durometer material hold grease under high compression. Two adjustable positions let you tune roll stiffness, and it ships in black hammertone or red powdercoat.
