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.\u003c\/p\u003e\u003cp\u003e1964-1966 Ford Mustang\u003c\/p\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":49210431733912,"sku":"9G9JI","price":2383.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0564\/0867\/0360\/files\/617412e92160187470efb50f42a84a4aL.jpg?v=1781041797","url":"https:\/\/frsport.com\/products\/qa1-64-66-ford-mustang-rear-suspension-conversion-system-single-adj-130lb-in-r123-130","provider":"FR SPORT","version":"1.0","type":"link"}
