Description

Do you have a high performance street/strip GM? The QA1 Double Adjustable Pro Coil System is the most versatile direct bolt-in front suspension system on the market today. Put down the welder and cutting tools because none of that is needed with this system - this system is designed to work with stock suspension and stock control arms!

 

Take control of your ride height and get the stance you have been looking for with this fully adjustable coil over. The Double Adjustable valving allows for easy adjustment from one type of driving to the next - drag racing, auto crossing, road course racing or simply getting groceries, the QA1 Double Adjustable Pro Coil System is the answer. Unlike many other shocks on the market, the valving between compression and rebound can be adjusted completely independent from one another, allowing for easy tunability no matter where you are driving.
