QA1 Circle Track Monotube Shock Absorbers

Monotube shocks have an area of oil and an area of gas separated by a floating piston. As the piston rod compresses or extends, the floating piston moves allowing the oil to stay stable while the rod is displaced.

Usually, when tracks are rough, a monotube shock absorber is preferred to help the car get through the ruts. The extra gas pressure in monotube shocks can keep the car from digging in and hooking a rut. Monotube shocks can also keep the oil cooler longer than a twin tube shock.

Shock Options to Fit Your Needs:

Hyperscrew (26 Series & 28 Series)
The hyperscrew equipped shocks have a threaded round port near the bearing end of the shock body. This hole is then sealed with a small screw that has a o-ring built into it, sealing the nitrogen gas pressure inside the shock.

Sealed Hyperscrew (26A Series & 28A Series)
The 26A and 28A Series shocks feature a sealed hyperscrew. The gas pressure of these shocks is only adjustable by QA1 and QA1 Authorized Rebuilders per sanctioning body, like IMCA, and track rules.

Schrader Valve (28V Series)
With a Schrader valve you can easily adjust your gas pressure. Much like adding air to your car tires, the Schrader valve allows you to make "on the fly" gas pressure adjustments between heat races and features to adjust for varying track conditions.
