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.\n\u003cbr\u003eProduct appearance and features may vary in the market as design changes, improvements and modifications are implemented.\n\u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cbr\u003e  \u003cli\u003eFront Adjustment Range: Camber -1.00° to +1.75° when combined with factory adjustment\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eFront Adjustment Range: Caster +1.00° to +5.00° when combined with factory adjustment\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eWorks with both OE Springs and Coilover kits\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003exAxis™ Sealed Flex Joint Bushings\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eBuilt-in 'Shelby Drop' Geometry\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eRequired: 1 per axle\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eSold as a pair\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e","brand":"SPC Performance","offers":[{"title":"Default Title","offer_id":54152739357044,"sku":"94219","price":845.66,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4365\/8612\/files\/6b9277ae4dcb82d15258dde3c1878093.jpg?v=1774302219","url":"https:\/\/downeastoffroad.com\/products\/spc-performance-67-73-ford-mustang-1st-gen-adjustable-upper-control-arm-caster-rod","provider":"Down East Offroad ","version":"1.0","type":"link"}
