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":46602345021657,"sku":"SPC94219","price":1159.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0040\/2689\/2361\/files\/6c064111177b63d1449f52dab3b1b103L.jpg?v=1746364155","url":"https:\/\/rawbrokerage.com\/products\/spc-performance-67-73-ford-mustang-1st-gen-adjustable-upper-control-arm-caster-rod","provider":"Raw Brokerage","version":"1.0","type":"link"}
