Upgrade your classic Mustang’s suspension with QA1’s Pro Coil System. Engineered for 1964–1966 Mustangs, this single adjustable coilover kit offers modern handling, ride quality, and stance adjustability in a straightforward, bolt-in package. Featuring a 10” coil spring with a 400 lb./in. rate, it’s an excellent choice for restomods and street-driven cars that need sharper handling and improved control. MODERN HANDLING & CONTROL Factory suspension designs limit tuning and performance. QA1’s single adjustable coilovers let you fine-tune rebound and compression together with 18 adjustment settings. With one knob, you can soften the ride for cruising or firm it up for aggressive driving, giving you the flexibility to match your Mustang’s style. RIDE HEIGHT FLEXIBILITY This system allows you to adjust ride height from factory stock height down to 2” lower. Whether you’re keeping an original look or going for a lower stance, QA1 Pro Coils let you achieve the right height without sacrificing suspension geometry or drivability. EASY BOLT-IN INSTALLATION No welding or cutting required. QA1 designed this system as a direct bolt-in replacement that installs with basic hand tools, making it a perfect upgrade for DIY enthusiasts.
