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

Update '64.5 to '66 Ford and Mercury front suspensions by installing this pair of adjustable upper control arms from SPC. Each arm has a built in +3.00° of caster to improve return-to-center with modern radial tires. The camber curve has also been optimized by utilizing the 'Shelby Drop' geometry in the billet aluminum cross shaft. Arm pivots are maintenance-free xAxis™ Sealed Flex Joints for tight, responsive handling. Camber can be set to -2.00°, -1.00°, or 0.00° for superior cornering, and kit includes .25° and .50° shims for fine-tuning. The adjustable caster rods feature high durometer OE-style bushings to protect the chassis mount and allows for easy caster adjustment, similar to later model Ford vehicles. These arms can be use d with either an OE style spring/shock or an aftermarket coilover kit. Arms feature a stock style ball joint and all of the required mounting hardware.
