# UMI Performance 70-81 GM F-Body Upper A-arms Front Tall Ball Joints

UMI’s 2nd Gen F-Body upper a-arms are a key component of a great handling muscle car. Our P/N 2653-1 upper a-arms add caster to improve steering feel and reduce wandering while incorporating a ½” taller than stock ball joint to improve camber gain. Strong tubular construction and UMI built Delrin bushings ensure precision performance and enhance steering response. The 4140 CrMo offset cross shaft permits camber adjustment to minimize shims required. Available in UMI red or gloss black powder coat. 100% designed, manufactured and raced with pride in the USA.
