{"product_id":"adjustable-rear-upper-control-arms-3-4-extended-red","title":"Adjustable Rear Upper Control Arms, 3\/4\" Extended, Red","description":"The Spohn Performance 635-EL adjustable rear upper control arms are engineered to significantly outperform the stock stamped-steel arms and soft rubber bushings found in 1977-1996 Chevrolet GM B-Body vehicles. These arms feature a 3\/4-inch extended length, crucial for accurately centering the wheel within the wheel well. Constructed from robust 4130N chrome moly tubing and fully TIG welded, they offer superior strength and lightweight performance.\n\nA key innovation is the Del-Sphere pivot joint, which combines the articulation of a spherical rod end with the noise-dampening qualities of a bushing. This design incorporates a spherical ball surrounded by Delrin bushing cups, allowing for 28 degrees of rotation without binding, which is essential for predictable traction during cornering. Unlike polyurethane bushings that can bind and stress mounting points, the Del-Sphere joint provides smooth suspension movement and is fully rebuildable.\n\nThe double adjuster, featuring right-hand and left-hand threads, allows for convenient on-car adjustments to set the pinion angle without needing to remove the control arm. The product is priced per pair, and the manufacturer notes that it is a backordered item with an ETA to be confirmed within 1-3 days of purchase.","brand":"Spohn Performance","offers":[{"title":"Default Title","offer_id":52866387247416,"sku":"635-EL","price":189.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687689528.webp?v=1787906993","url":"https:\/\/store.motormia.co\/products\/adjustable-rear-upper-control-arms-3-4-extended-red","provider":"MOTORMIA","version":"1.0","type":"link"}
