QA1 Pro Coil Shock Kit MD402-10500C

Take your classic Mustang’s suspension to the next level with QA1’s Front Pro Coil System. Purpose-built for 1967–1973 Mustangs, this kit combines modern adjustability with heavy-duty spring rates to handle the additional weight of ’67-‘73 Mustangs. Featuring 10” coil springs with a 500 lb./in. rate, it’s the ideal solution for drivers who demand sharper handling, firmer ride control, and the durability to manage higher horsepower and cornering loads. FULLY TUNABLE WITH DOUBLE ADJUSTABILITY QA1’s double adjustable shocks give you independent control of rebound and compression, each with 18 clicks of adjustment. This lets you fine-tune suspension behavior for daily comfort, aggressive street driving, or even track use - dialing in the perfect balance of ride and performance. SPRINGS OPTIMIZED FOR ’67–’73 MODELS The included 500 lb./in. springs are tailored specifically for the added front-end weight of 1967–1973 Mustangs with big block engines. They deliver firmer control while maintaining drivability, ensuring your Mustang feels planted and predictable at all times. RIDE HEIGHT FLEXIBILITY Easily adjust ride height from factory stock height down to 2” lower. Whether you prefer a stock appearance or a lowered stance, QA1 coilovers let you fine-tune your setup without compromising geometry or handling. BOLT-IN INSTALLATION Built as a true bolt-in system, QA1 Pro Coils require no welding or cutting. With powder-coated springs, premium hardware, and straightforward installation, you’ll be back on the road quickly with a suspension that’s built to last.
