SPC Performance Steel Upper Adjustable Control Arm & Caster Rod 64.5-66 Ford Mustang (Pair)

If you're working on a '64.5 to '66 Ford Mustang, this pair of adjustable upper control arms and caster rods from SPC Performance is designed to significantly update your front suspension. These arms are built to improve how your classic Mustang handles, especially with modern radial tires. They incorporate +3.00 degrees of caster right into the arm itself, which helps the steering wheel return to center more easily after turns. This is a big help when you're driving a car that was originally set up for bias-ply tires.

SPC has also optimized the camber curve by building in the 'Shelby Drop' geometry into the billet aluminum cross shaft. This means you can achieve better cornering performance. You can adjust the camber to -2.00°, -1.00°, or 0.00° using the ball joint plate positioning, and the kit includes .25° and .50° shims for fine-tuning your alignment. The control arms use maintenance-free xAxis™ Sealed Flex Joints for the arm pivots, giving you tight and responsive handling without the need for constant upkeep. The adjustable caster rods feature high durometer OE-style bushings that protect the chassis mount and allow for straightforward caster adjustments, similar to how later model Fords are set up.

These control arms are versatile and can be used with either your original style spring and shock setup or an aftermarket coilover kit. They come equipped with a stock-style ball joint and include all the necessary mounting hardware to get the job done. This kit is sold as a pair, with one set for each side of the front axle.
