Stock Mount Front and Rear Coil-Over Conversion Systems

Whether you’re looking for an adjustable 90-10 style drag strut or a soft comfortable street ride or a firmer strut for autocross, QA1’s Mustang Pro Coil System has what you need. With multiple valving options including double adjustable, single adjustable and drag “R” series adjustable, you can choose the flexibility you’re looking for. You can also choose from many different spring rates to match the weight of your vehicle and your personal ride preference.

QA1 also offers bolt-in double and single adjustable Rear Coil-Over Conversion Kits for 1979-2004 Mustangs. With our highly popular adjustable struts and the addition of the Rear Coil-Over Conversion Kit, you can now get a complete suspension makeover for both ends of the vehicle.

All QA1 steel struts and aluminum shocks are made in the U.S.A. and are 100% dyno tested and serialized to ensure your struts and shocks are of the highest quality.
