UMI Performance 64-72 GM A-Body Front Upper A-arms Adjustable 1/2in Taller Ball Joints

NOTE : The UMI 4056-2 upper a-arm is designed to work primarily with lowered cars. We do not recommend using the 4056-2 with cargo coils or above stock height cars, as the bump stop may contact the cross brace. UMI*s adjustable upper a-arms with taller ball joints are designed to work with factory height spindles. UMI is not responsible for fitment issues which may arise from using incompatible components.
