Designed for 1967-1970 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 double adjustable shocks allow you to fine-tune performance and handling, giving your Mustang a balance of comfort and control.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.\u003cbr\u003e\u003cbr\u003eThis Part Fits:\u003cp\u003e\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1967-1970\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1969-1970\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eBoss 302\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1969-1970\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eBoss 429\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1970\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eGrande\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1970\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eMach 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1967-1970\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eShelby GT-350\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1967-1970\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eShelby GT-500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1968\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eShelby GT-500KR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":55021673382056,"sku":"QAPR224-150","price":2597.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0402\/2344\/1064\/files\/80d4072794f22b1b4da14cbe93c69f5cL.jpg?v=1767039933","url":"https:\/\/www.truspeedperformance.com\/products\/qa1-67-70-ford-mustang-rear-four-link-suspension-kit-double-adj-150lb-in","provider":"TruSpeed Performance LLC","version":"1.0","type":"link"}
