Improve your Mustang's suspension with QA1's bolt-in rear coil-over conversion kit. This kit includes specially designed mounting brackets, adjustable aluminum shocks, springs, and all necessary hardware.
Ride Height Adjustability
We understand that achieving the perfect stance for your car can be a challenge. That's why we've created a solution that makes it easy to adjust your ride height. QA1 coilovers feature a fully threaded, aluminum body which allows up-to 2” of lowering from stock.
Single-Adjustable Coil-Overs
QA1’s 18-way adjustable single-adjustable shocks are tailored for street-driven cars that also hit the track. With a simple turn of the knob, you can adjust your shocks for a comfortable ride or a more aggressive valving, depending on your needs.
EASY, BOLT-IN INSTALLATION
Our commitment to thoughtful product design is evident in every product we produce, to deliver the highest level of performance, while ensuring trouble-free compatibility.
