Reduce body roll and improve the handling of your 1964-1972 A-Body with a Rear Sway Bar Kit from BMR's suspension! Stock sway bars have low torsional spring rates because they are manufactured from small diameter bar stock or tubing. BMRs Non-Adjustable Rear Sway Bar Kit (SB402) increases sway bar rate and is designed for street performance, autocross, and road racing applications. When performance is a must, rely on BMR's suspension!
