{"product_id":"spc94219-spc-performance-control-arms","title":"SPC Performance 67-73 Ford Mustang 1st Gen Adjustable Upper Control Arm \u0026 Caster Rod","description":"\u003cp\u003eUpdate '68 to '73 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.\u003c\/p\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/d0054326e008edb5c26f790d309cd465.PDF\" title=\"Installation instructions\" aria-label=\"Visit a webpage about Installation instructions\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e","brand":"SPC Performance","offers":[{"title":"Default Title","offer_id":48276561625303,"sku":"SPC94219","price":1159.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0791\/9815\/9063\/files\/spc-performance-67-73-ford-mustang-1st-gen-adjustable-upper-control-551.jpg?v=1777465115","url":"https:\/\/www.undergrounddynamics.com\/products\/spc94219-spc-performance-control-arms","provider":"Underground Dynamics","version":"1.0","type":"link"}
