QA1 26A72-4M Details

The 26 Series shock is a one piece monotube shock that is well suited for a variety of track conditions or as a traction shock in various applications.
Constructed with a zinc plated body for corrosion resistance, this shock is a popular choice for modifieds, late models, super stocks 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.
Made with a 2'' O.D. zinc plated steel monotube body and available with hyperscrew, sealed Hyperscrew (IMCA Legal) or Schrader valve configurations, the 26 Series shocks use deflective disc valving with either linear, digressive or linear/digressive valving.
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.
The gas pressure of the sealed hyperscrew configurations is only adjustable by QA1 and QA1 Authorized Rebuilders per sanctioning body, like IMCA, and track rules.
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.
The 46 MM piston allows for maximum car control at all shaft velocities.
They are racer rebuildable and revalveable for unparalleled repeatability.
Made in the USA and 100% dyno tested and serialized.
