Designed for 1964–1966 Mustangs, this single adjustable four-link replaces the factory leaf springs with a modern suspension system that delivers improved traction, adjustability, and ride quality. Whether you’re building a street machine or a track-capable restomod, QA1’s four-link gives you the control and confidence you need. MODERN HANDLING FOR YOUR CLASSIC MUSTANG Factory leaf springs were never designed for today’s performance expectations. QA1’s four-link suspension eliminates axle wrap, controls wheel hop, and keeps the tires planted under hard acceleration and cornering. The 18-click, single adjustable shocks allow you to fine-tune ride quality and handling, giving your Mustang a balance of comfort and performance. RIDE HEIGHT \u0026amp; ADJUSTABILITY This kit offers a ride height adjustment range from the stock ride height to 3” lower than factory. That means you can dial in the perfect stance for your build, whether you’re looking for a lowered, aggressive look or stock-like ride height with modern performance benefits. WELD-IN INSTALLATION For maximum strength and durability, this kit requires welding during installation. QA1 engineered the brackets to be self-fixturing, making the process as straightforward as possible. Once installed, the system integrates seamlessly into your Mustang chassis.\n\u003cbr\u003e1964-1966 Ford Mustang\n\u003cbr\u003eFITMENT NOTES: Fits 1964–1966 Ford Mustangs: Designed for use with factory or QA1 9” rear housings: Welding required for installation: Single adjustable shocks included\n\u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cbr\u003e  \u003cli\u003ePolyurethane bushings reduce noise while maintaining strength\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eComplete kit includes shocks, brackets, hardware, and links\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eSingle adjustable shocks for fine-tuning ride and handling\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eSelf-fixturing weld-in brackets for easier installation\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eWorks with factory axle housings or QA1 9” housings\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eRide height adjustability: 3” of adjustment\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eProvides predictable traction and stability\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003ePowder-coated components for durability\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eEliminates axle wrap and wheel hop\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eFits 1964–1966 Ford Mustangs\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbdoy\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNumber Of Boxes: 3\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbdoy\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":46174923653273,"sku":"qapR123-130","price":2424.05,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/2611\/3689\/files\/617412e92160187470efb50f42a84a4aL.jpg?v=1771421762","url":"https:\/\/msvracingpowersports.com\/products\/qa1-64-66-ford-mustang-rear-suspension-conversion-system-single-adj-130lb-in","provider":"MSV Racing","version":"1.0","type":"link"}
