Upgrade your classic Mustang’s front suspension with QA1’s Pro Coil System. Designed specifically for 1964 - 1966 Mustangs, this single adjustable coilover kit delivers modern handling, ride quality, and stance adjustability in an easy-to-install package. Featuring a 10” spring with a 350 lb./in. rate, it’s the perfect solution for street performance or restomod builds that demand both comfort and control. MODERN HANDLING & ADJUSTABILITY Factory suspension setups limit tuning and performance. With QA1’s single adjustable coilovers, you can dial in rebound and compression with a simple turn of the knob, letting you fine-tune ride quality and handling for daily driving or spirited performance. RIDE HEIGHT FLEXIBILITY This system allows you to adjust ride height from factory stock height down to 2” lower. Whether you want to maintain an original look or achieve a more aggressive stance, QA1 Pro Coils let you fine-tune without sacrificing geometry or drivability. EASY BOLT-IN INSTALLATION No cutting, welding, or fabrication required. QA1’s Pro Coil System is designed for straightforward installation with basic tools, with either factory, or QA1 tubular control arms.
