UMI's adjustable front upper A-arms for 1964–1972 A-body cars precisely locate a 1/2" taller upper ball joint to improve the camber curve and front-end grip. The design relocates the ball joint plate rearward for added caster and better steering feel; machined CrMo cross shafts and precision rod ends provide fine adjustment. Supplied with hardware recommendations and alignment specs, these arms are hand-built in the USA.
