Upgrade your 1967-1973 Mustang with QA1's Pro Coil System for modern performance and stance adjustability. This single adjustable coilover kit delivers sharper handling, ride quality, and durability in a direct bolt-in package. Featuring 10" coil springs with a 500 lb./in. rate, this system is specifically tailored for the heavier weight of 67-73 Mustangs with big block engines, giving you the right balance of support, comfort, and control. MODERN HANDLING & ADJUSTABILITY QA1's single adjustable coilovers provide 18 settings of rebound and compression control combined in one knob. Easily dial softer settings for cruising or firmer settings for aggressive cornering, letting you tune your Mustang for any driving style.

Whether you want to preserve a factory stance, achieve a more aggressive look, or fine-tune for wheel/tire fitment, QA1 Pro Coils let you make changes without compromising suspension geometry. EASY BOLT-IN INSTALLATION Direct-fit design means no cutting or welding required. QA1's Pro Coil System bolts in with standard tools, making it one of the most straightforward suspension upgrades available for your classic Mustang.
