Transform your classic Mustang’s suspension with QA1’s Pro Coil System. Designed for 1964–1966 Mustangs, this single adjustable coilover kit offers modern ride quality, handling, and stance adjustability in an easy bolt-in package. Featuring a 10” coil spring with a 450 lb./in. rate, this system is ideal for drivers who want a firmer ride and enhanced cornering performance without going to a full track setup. MODERN HANDLING & CONTROL Stock suspensions were never built for today’s performance demands. With QA1’s single adjustable coilovers, you can fine-tune rebound and compression together across 18 settings. A single adjustment knob makes it easy to soften the ride for the street or firm it up for more spirited driving. RIDE HEIGHT FLEXIBILITY Get the stance you want without sacrificing drivability. This system allows you to adjust ride height from factory stock height down to 2” lower, perfect for dialing in wheel/tire fitment or achieving a more aggressive look. EASY BOLT-IN INSTALLATION No welding or cutting required. QA1 Pro Coils are designed as direct bolt-in replacements for factory, or QA1 tubular components, making them one of the easiest suspension upgrades you can install at home.
