Modernize your '64.5 to '66 Ford front suspension by installing an adjustable upper control arm and adjustable strut rod 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 kit includes .25° and .50° shims for fine-tuning. Use this arm with either an OE style spring/shock or an aftermarket coilover kit. SPC's arm comes equipped with a stock style ball joint and all of the mounting hardware.

Adjustable Caster Rod - 94220 If you are running modern radial tires you should not follow factory alignment specifications for caster, SPC recommends 3˚ of caster to promote return to center steering. Stock strut rods on 1st generation Mustangs are non-adjustable and often have worn bushings that can cause unwanted movement of the lower rod assembly and poor handling. A must for early Mustangs, SPC's adjustable caster rod features low durometer OE-style bushings to protect the chassis mount from damage and has easy caster adjustment. This adjustable strut rod will provide the positive caster needed for improved tracking and modern geometry. If you want additional caster or want to adjust camber, check out SPC control arm kit #94215 (above).
