Modernize your Mustang’s suspension from 1967 to 1973 with QA1’s Pro Coil System.
This coilover kit adjustable single combines ride quality, performance handling, and stance adjustability in an easy bolt-in package.
Featuring a coil spring 10” with a rate of 400 lb./in., it’s the perfect solution for street performance and restomod builds that demand sharper handling with a comfortable ride.
QA1 single adjustable coilovers allow you to fine-calibrate rebound and compression together with 18 settings of adjustment.
With a simple turn of the knob, you can soften the ride for cruising or firm it up for aggressive driving.
This system lets you adjust ride height from factory stock height down to 2” lower, giving you control over stance, wheel/tire fitment, and handling balance without sacrificing suspension geometry.
No welding, cutting, or major modifications are needed for installation.
QA1 designed this kit as a direct bolt-in upgrade for classic Mustangs, making it an easy DIY-friendly installation.
