Hellwig 1-1/8" Tubular Rear Sway Bar for 1964–1967 GM A‑Body vehicles. This rear bar mounts to the axle and frame (not control arms) to increase roll stiffness and stabilize the rear during cornering for improved handling. Some installations may require drilling; the adjustable-rate design offers tailored rear roll control for classic A‑body cars.
