Ready to bolt on control arm sets for your 63-76 A-Body Mopar. They feature tubular construction, black powder coat and polyurethane inner pivot bushings. Stronger than the factory control arms without adding any weight, these upper control arms increase caster by approximately 3 degrees. Each set comes with ball joints. Made in the USA. This part is only for factory cars and any A-Body that was swapped to disc brakes with factory parts (large ball joint).
