{"product_id":"rear-upper-control-arm-bushings","title":"Rear Upper Control Arm Bushings","description":"The Maximum Motorsports E4SZ-5A is a pair of differential side (aft) upper control arm bushings for 1979-2004 Ford Mustangs equipped with 7.5\" and 8.8\" solid rear axles. These bushings are crucial for replacing worn components when installing new rear upper control arms, ensuring proper suspension articulation.\n\nThe chassis side (forward) bushings are integral to the control arm itself and are not part of this product. It is recommended to use rubber bushings for this application, as urethane bushings can cause binding and lead to chassis damage due to the necessary twisting and pivoting motion of the upper control arms during axle travel.\n\nMaximum Motorsports offers a specialized bushing removal and installation tool (MMT-1) designed to make the replacement process significantly easier. The manufacturer notes that these bushings are a common wear item, especially for vehicles used in performance driving or track applications, and replacement is recommended for Mustangs from 1979-2004, particularly if they have not yet been converted to a torque arm setup, which eliminates the upper arms entirely.\n\nBoth Ford and trusted vendors supply these bushings, and Maximum Motorsports has determined that they are manufactured by the same source and are of equal quality. Due to stock rotation, it is not possible to specify the exact source of the bushings when purchased.","brand":"Maximum Motorsports","offers":[{"title":"Default Title","offer_id":52662956359992,"sku":"E4SZ-5A","price":55.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687503148.jpg?v=1784322012","url":"https:\/\/store.motormia.co\/products\/rear-upper-control-arm-bushings","provider":"MOTORMIA","version":"1.0","type":"link"}
