{"product_id":"spc94218-spc-performance-control-arms","title":"SPC Performance Steel Upper Adjustable Control Arm \u0026 Caster Rod 64.5-66 Ford Mustang (Pair)","description":"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 used 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.","brand":"SPC Performance","offers":[{"title":"Default Title","offer_id":48276561559767,"sku":"SPC94218","price":1112.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0791\/9815\/9063\/files\/spc-performance-steel-upper-adjustable-control-arm-caster-rod-64-5-673.jpg?v=1777465105","url":"https:\/\/www.undergrounddynamics.com\/products\/spc94218-spc-performance-control-arms","provider":"Underground Dynamics","version":"1.0","type":"link"}
