Bring modern suspension performance to your classic Mustang with QA1's Pro Coil System. Specifically designed for 1964-1966 Mustangs, this double adjustable coilover kit delivers full control over ride quality, stance, and handling. With 10" coil springs rated at 400 lb./in., this setup strikes the ideal balance between ride comfort and sharper performance for aggressive street driving or entry-level competition builds. FULL CONTROL WITH DOUBLE ADJUSTABILITY QA1's double adjustable shocks feature independent rebound and compression control with 18 clicks each. This allows you to fine-tune how your Mustang handles bumps, weight transfer, and cornering grip. Whether you're cruising, carving backroads, or setting up for a track day, this system puts you in complete control. RIDE HEIGHT FLEXIBILITY Easily dial in the perfect stance with ride height adjustment from factory stock height down to 2" lower. Lower your Mustang for an aggressive look, improve handling balance, or fine-tune for wheel and tire clearance without sacrificing geometry. EASY BOLT-IN INSTALLATION No welding, no cutting. The Pro Coil System installs with basic hand tools as a direct bolt-in upgrade, making it an accessible DIY-friendly solution for classic Mustang owners.
