Valving Options for Circle Track Shocks

QA1's circle track shocks are offered in a variety of valvings. Our rebuildable circle track shocks allow racers to even change the valving on any shocks with a tuning kit, so you can get exactly what you want should your valving needs change.

Multiple Valvings for Street Performance & Racing Shocks and Struts

No matter if you drag race, autocross, road race or just go for the casual cruise, QA1’s shocks and struts are available in several different valving configurations to give you the perfect ride and performance based on your situation. Each click on QA1’s adjustable shocks and struts has been carefully and precisely defined from extensive research, testing and real-world experience to provide the perfect setting for each adjustment.

QA1’s shocks and struts are optimized to enhance performance by providing a soft, comfortable ride at the low end of operation or a firm, high performance ride at the high end of operation. Changing the valving on adjustable shocks and struts is as simple as turning the knob on the base of the shock, giving you the versatility to go from the strip to the street without ever removing the shock or strut from the vehicle.
