{"product_id":"speedtech-suspension-subframe-122231","title":"Speedtech Suspension Subframe 122231","description":"The Speedtech ExtReme front subframe delivers an all-new take on geometry and quality for your 62-67 Chevy II, giving you wide tire fitment, maximized rigidity, and serious handling performance — whether on the track or the street. Engineered with proprietary geometry and tuned with QA1 or JRi coilovers and a precision dual-power rack from Sweet Mfg., the system provides predictable, connected feedback with a refined ride quality that doesn’t compromise drivability. Optimized suspension geometry, forged aluminum spindles, and clearance for up to 315mm front tires ensure every aspect is engineered for real-world performance. AGGRESSIVE STANCE, WIDE TIRE FITMENT Designed with wide wheel and tire combos in mind, this subframe accommodates up to a 315\/30\/18 tire with full steering clearance. High-clearance control arms and optimized geometry let you slam the car for that strong pro-touring look without compromising performance or drivability. PRECISION STEERING FEEL, DUAL RACK PERFORMANCE At the heart of this system is a dual power rack and pinion from Sweet Mfg., giving you a quicker ratio and improved feedback for confident cornering. Combined with our billet steering arm and ExtReme spindle geometry, you’ll feel in full control at every turn. RACE-BRED STRENGTH, STREET-READY RELIABILITY Box-welded construction with tabbed-through gusseting maximizes torsional rigidity, while our 7075 forged aluminum spindles bring lightweight strength to the front end. It’s engineered to take abuse—on and off the track.\r\n\u003cul\u003e\t\u003cli\u003eEngineering-Led Precision\u003c\/li\u003e\r\n\t\u003cli\u003eComplete Performance Solutions, Built to Work Together\u003c\/li\u003e\r\n\t\u003cli\u003eProven Performance, Tested and Refined for Real-World Performance\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eAttributes:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eBrand Name: \u003c\/b\u003eSpeedtech Performance\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGTIN: \u003c\/b\u003e00806990175649\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eEmission Code: \u003c\/b\u003e43\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eManufacturer Part Number: \u003c\/b\u003e122231\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eExtended Information:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\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\r\n\r\n\u003ch3\u003ePacking Information:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\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\u003e77 x 49 x 29 inches\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eWeight: \u003c\/b\u003e550 POUNDS\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003ePDF:\u003c\/h3\u003e\r\n\u003cp\u003e\r\n\u003c\/p\u003e\u003cdiv\u003e\u003ca href=\"https:\/\/sdda.semadata.org\/Standard\/QA1\/9919-434_REV_02262026%2062-67%20GM%20X-BODY%20EXTREME%20SUBFRAME.pdf\" target=\"_blank\"\u003e\u003cimg src=\"data:image\/png;base64,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\" style=\"display:inline\"\u003e \u003c\/a\u003e\u003c\/div\u003e\r\n\r\n\u003cdiv id=\"sema-product-fitment\" class=\"product__accordion accordion fitment\"\u003e\u003c\/div\u003e","brand":"Speedtech Performance","offers":[{"title":"Default Title","offer_id":44804279795757,"sku":"JYGW-122231","price":17997.02,"currency_code":"USD","in_stock":true}],"url":"https:\/\/montgomeryparts.com\/products\/speedtech-suspension-subframe-122231","provider":"Montgomery Parts","version":"1.0","type":"link"}
