Modernize your early Ford and Mercury front suspension by installing these adjustable upper control arms and adjustable strut rods from SPC. SPC has built +3 of caster into the upper arm to improve return to center with today's radial tires. The adjustable strut rod features low durometer OE-style bushings to protect the chassis mount and allows for easy caster adjustment, similar to later Ford vehicles. The camber curve has been optimized by building Shelby Drop geometry into the billet aluminum cross shaft. Camber can be adjusted by positioning the ball joint plate to 0, -1, or -2 and fine-tuning using the factory adjuster. Use these arms with either an OE style spring/shock or an aftermarket coilover kit. SPC's arms come equipped with stock style ball joints and all of the mounting hardware.
