{"product_id":"qa1-coilover-4-link-r223-130","title":"QA1 Coilover 4 Link R223-130","description":"Transform the way your early Mustang handles with QA1’s rear four-link kit. 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 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.\r\n\u003cul\u003e\t\u003cli\u003eFits 1964–1966 Ford Mustangs\u003c\/li\u003e\r\n\t\u003cli\u003eComplete kit includes
