Drastically reduce body roll and improve cornering stability with this UMI Performance solid sway bar kit. Engineered for the 1964-1972 GM A-Body platform, this kit replaces narrow, worn factory bars with high-performance 4140 Chromoly (CrMo) steel components. The 1.250-inch front sway bar is 400% more rigid than the original 7/8-inch factory bar, while the 1-inch solid rear bar is heat-treated to ensure long-lasting memory and consistent performance under load.

The front bar is CNC-bent for a precise fitment within the factory mounting points, while the rear bar is formed as a single piece for maximum structural integrity. Each kit includes high-quality end links, greaseable polyurethane bushings, and Grade 8 mounting hardware for a complete, bolt-on installation. 100% manufactured in the USA.
