Modernize your 1967–1973 Mustang’s suspension with QA1’s Pro Coil System. This single adjustable coilover kit combines ride quality, performance handling, and stance adjustability in an easy bolt-in package. Featuring a 10” coil spring with a 400 lb./in. rate, it’s the perfect solution for street performance and restomod builds that demand sharper handling with a comfortable ride. MODERN HANDLING & ADJUSTABILITY QA1 single adjustable coilovers allow you to fine-tune rebound and compression together with 18 settings of adjustment. With a simple turn of the knob, you can soften the ride for cruising or firm it up for aggressive driving. RIDE HEIGHT FLEXIBILITY This system lets you adjust ride height from factory stock height down to 2” lower, giving you control over stance, wheel/tire fitment, and handling balance without sacrificing suspension geometry.
