Rear control arms are one of the most important suspension upgrades for a GM G-Body. Factory stamped-steel arms suffer from bushing deflection and corrosion that contribute to traction loss and vague handling. This tubular upper and lower kit is a direct bolt-on replacement built to minimize wheel hop, improve cornering, and keep the car more consistent whether it is a weekend cruiser or a track car. The greaseable polyurethane bushings are a significant improvement over worn OEM rubber, adding ride control while reducing traction loss. The lower arms include sway bar mounting holes sized for the factory bar and most aftermarket bars. UMI Performance manufactures this kit in the USA.
