UMI Performance 1970-81 GM F-Body Front Upper Adjustable A-Arm Kits

UMI 2nd Gen F-body adjustable upper A-arms are race-worthy components equally at home on the street. They add 5 to 6 degrees of caster to improve steering feel and reduce wandering. Their single adjustable rod end design allows for caster and camber adjustment with zero or minimal shimming, while the strong 1.250 in. DOM steel tubular construction and 4140 chromoly cross shafts give peace of mind when road racing, drag racing, or simply corner carving in the mountains.

UMI Performance 1970-81 GM F-body front upper adjustable A-arm kits are offered with stock or 1/2 in. taller-than-stock ball joints for improved camber gain and enhanced cornering traction. They are available in UMI red or gloss black powdercoat. Choose the preferred kit for your vehicle.
