BMR's SB762 rear hollow sway bar for S550 Mustang is a 22mm DOM steel bar cold-formed for torsional strength and long-lasting memory. The hollow design yields high strength at reduced weight while delivering a 29–41% increase in rate over the stock bar. It mounts with 88‑durometer, internally fluted polyurethane bushings to reduce deflection, is CNC-formed for accuracy, and is available in durable black hammertone or red powdercoat for improved handling with a 1–2 hour install time.
