{"product_id":"qa1-suspension-system-r210-170s","title":"QA1 Suspension System R210-170S","description":"Upgrade the rear suspension of your 1963-1972 Chevrolet C10 with a complete QA1 Rear Suspension System, paired with a standard-width 9-inch housing and 31-spline axles. This system combines double-adjustable coil-over performance with straightforward wheel and tire fitment. The standard-width housing maintains the factory 63-5\/8\" wheel mounting surface width, making it easy to build around common wheel and tire combinations while maintaining the factory rear track width. FACTORY WIDTH FOR EASY WHEEL FITMENT The included 9-inch housing features a 63-5\/8\" wheel mounting surface width that matches the factory width. This makes wheel and tire selection more straightforward while maintaining the track width your C10 was originally designed around. The housing includes 31-spline axles, Big Ford New Style Torino housing ends with a 2.5\" axle offset and dual 5x4.75\" and 5x5\" bolt patterns for compatibility with a wide range of brake and wheel combinations. MODERN COIL-OVER PERFORMANCE Replace the factory rear suspension with a performance-focused coil-over system designed to improve suspension control and give your C10 a more responsive, modern driving experience. DOUBLE-ADJUSTABLE COIL-OVERS QA1 double-adjustable shocks let you independently tune compression and rebound, giving you greater control over how your truck responds to different road conditions and driving styles. With 18 positions of adjustment for each, you can fine-tune ride quality, handling and traction for street driving or more performance-focused use. The included 170 lb\/in. springs are a great choice for street-driven trucks, providing a balance of ride quality and performance.\r\n\u003cul\u003e\t\u003cli\u003eEasy wheel and tire fitment: Standard 63-5\/8\" wheel mounting surface width maintains the factory rear track width.\u003c\/li\u003e\r\n\t\u003cli\u003eModernize your C10 suspension: Coil-over suspension provides greater suspension control and a more performance-focused driving experience.\u003c\/li\u003e\r\n\t\u003cli\u003eFine-tune ride and handling: Double-adjustable coil-overs provide independent compression and rebound adjustment for greater control over suspension behavior.\u003c\/li\u003e\r\n\t\u003cli\u003eBuild around your preferred wheels and brakes: Dual 5x4.75\" and 5x5\" bolt patterns and Big Ford New Style Torino housing ends provide compatibility with a wide range of combinations.\u003c\/li\u003e\r\n\t\u003cli\u003eStart with a complete, matched system: Suspension components, coil-overs, standard-width 9-inch housing and 31-spline axles are packaged together to simplify your build.\u003c\/li\u003e\r\n\t\u003cli\u003ePerformance you can count on: QA1 shocks are 100% dyno tested and serialized. \u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\t\t\t\t\u003cdiv class=\"product__accordion accordion\"\u003e\n\t\t\t\t\u003cdetails\u003e\n\t\t\t\t  \u003csummary aria-expanded=\"false\"\u003e\n\t\t\t\t\t\u003cdiv class=\"summary__title\"\u003e\u003ch2 class=\"h4 accordion__title\"\u003eAttributes\u003c\/h2\u003e\u003c\/div\u003e\n\u003cspan class=\"icon-caret\"\u003e\u003c\/span\u003e\t\t\t\t\t\n\t\t\t\t  \u003c\/summary\u003e\n\t\t\t\t  \u003cdiv class=\"accordion__content\"\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eBrand Name: \u003c\/b\u003eQA1\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGTIN: \u003c\/b\u003e00806990238207\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eFront Shock Type: \u003c\/b\u003eNone\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eManufacturer Part Number: \u003c\/b\u003eR210-170S\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eUPC: \u003c\/b\u003e806990238207\u003c\/li\u003e\r\n\u003c\/ul\u003e\u003c\/div\u003e\n\t\t\t\t\u003c\/details\u003e\n\t\t\t\t\u003c\/div\u003e\r\n\t\t\t\t\u003cdiv class=\"product__accordion accordion\"\u003e\n\t\t\t\t\u003cdetails\u003e\n\t\t\t\t  \u003csummary aria-expanded=\"false\"\u003e\n\t\t\t\t\t\u003cdiv class=\"summary__title\"\u003e\u003ch2 class=\"h4 accordion__title\"\u003eExtended Information\u003c\/h2\u003e\u003c\/div\u003e\n\u003cspan class=\"icon-caret\"\u003e\u003c\/span\u003e\t\t\t\t\t\n\t\t\t\t  \u003c\/summary\u003e\n\t\t\t\t  \u003cdiv class=\"accordion__content\"\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eCountry of Origin: \u003c\/b\u003eUnited States\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eEmissions : \u003c\/b\u003eEmissions Compliance Exempt\u003c\/li\u003e\r\n\u003c\/ul\u003e\u003c\/div\u003e\n\t\t\t\t\u003c\/details\u003e\n\t\t\t\t\u003c\/div\u003e\r\n\t\t\t\t\u003cdiv class=\"product__accordion accordion\"\u003e\n\t\t\t\t\u003cdetails\u003e\n\t\t\t\t  \u003csummary aria-expanded=\"false\"\u003e\n\t\t\t\t\t\u003cdiv class=\"summary__title\"\u003e\u003ch2 class=\"h4 accordion__title\"\u003ePacking Information\u003c\/h2\u003e\u003c\/div\u003e\n\u003cspan class=\"icon-caret\"\u003e\u003c\/span\u003e\t\t\t\t\t\n\t\t\t\t  \u003c\/summary\u003e\n\t\t\t\t  \u003cdiv class=\"accordion__content\"\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eQuantity of Each: \u003c\/b\u003e1\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003ePackage UOM: \u003c\/b\u003eEA\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eDimension: \u003c\/b\u003e9.5 x 24 x 8 inches\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eWeight: \u003c\/b\u003e86 POUNDS\u003c\/li\u003e\r\n\u003c\/ul\u003e\u003c\/div\u003e\n\t\t\t\t\u003c\/details\u003e\n\t\t\t\t\u003c\/div\u003e\r\n\r\n\u003cdiv id=\"sema-product-fitment\" class=\"product__accordion accordion fitment\"\u003e\u003c\/div\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":63497462153356,"sku":"BJGM-R210-170S","price":5345.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/3848\/8460\/files\/9-inch-rear-Kits.63-72-text-0025_7214808e-d962-4c57-8aa7-41ed055d1c56.jpg?v=1793071033","url":"https:\/\/sema-search.myshopify.com\/products\/qa1-suspension-system-r210-170s","provider":"SEMA search","version":"1.0","type":"link"}
