26 Series Steel Monotube Shock

Circle Track Monotube Shock Absorber

The 26 Series shock is designed to be a rock-solid monotube shock that shines on both dirt and asphalt tracks. The zinc-plated body provides excellent corrosion resistance and consistency. With a variety of piston and valving options available, the 26 Series can handle extreme compression and rebound forces for both dirt and asphalt tracks.

This shock is a popular choice for modifieds, late models, superstocks and various other classes. Works best on rough tracks and as an easy-up shock on many dirt cars, and on bumpy asphalt tracks in all banking types.

Hyperscrew vs. Sealed Hyperscrew (IMCA legal) vs. Schrader Valve

Hyperscrew (26 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 an o-ring built into it, sealing the nitrogen gas pressure inside the shock.

Sealed Hyperscrew (26A Series)
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 (26V 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.
