Description
Transform the way your early Mustang handles with QA1’s rear four-link kit. 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 & 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.
