Part #: MS402-10450C
Upgrade your 1967-1973 Mustang's suspension with QA1's Pro Coil System. This single adjustable coilover kit combines modern handling, ride quality, and stance adjustability in an easy bolt-in package. Featuring 10" coil springs with a 450 lb./in. rate, it's the firmest single adjustable option available, delivering sharper cornering and reduced body roll for aggressive street performance and restomod builds. MODERN HANDLING & ADJUSTABILITY With QA1's single adjustable coilovers, you can fine-tune rebound and compression together with 18 settings of adjustment. One knob makes it simple to soften the ride for cruising or firm it up for maximum handling response. RIDE HEIGHT FLEXIBILITY This system allows you to adjust ride height from factory stock height down to 2" lower, giving you flexibility to fine-tune stance, handling balance, and wheel/tire clearance while maintaining proper geometry. EASY BOLT-IN INSTALLATION No cutting or welding required. QA1 designed this kit as a direct bolt-in upgrade for classic Mustangs, making it a DIY-friendly option that delivers modern suspension performance with minimal effort.
