This ST Suspensions rear anti-sway bar reduces body roll and sharpens turn-in on the 1979-2004 Ford Mustang and Mercury Capri (Fox and SN95) by cutting the load difference between the inside and outside tires through a corner. Cold-formed spring steel, multi-stage quenched and tempered, epoxy/powder coated, with composite bushings. A staple handling upgrade for flatter, more controlled cornering. Made in the USA.
