PST offers replacement upper control arms for 1962-72 B-Body and 1970-74 E-Body models. An inherent problem that has plagued the Mopar stamped steel arms over the years is the installation design of the upper ball joints. Repeated replacement of the ball joints over the years can strip and distort the opening of the control arm leading to ball joint "popping out" under load. PST's new arms come pre-assembled ready for quick installation. Improve handling, save time and money while retaining that factory look.
