A 19 mm (3/4 in) rear anti-sway bar cold formed from heavy-duty aircraft steel, then quenched and tempered through multiple cycles and finished in epoxy powder coating against road salt and stone chips. Adding rear roll stiffness shifts the lateral load transfer rearward, which trims understeer and keeps the inside front tire loaded through a corner, so turn-in sharpens and mid-corner grip improves. High-quality composite bushings reduce deflection so the bar transfers load rather than absorbing it. Bushings and mounting hardware are included. Made in the USA.
