QA1 26 Series Monotube Shock Absorber - 9in Stroke - Hyperscrew - 3-8 Valving - Steel

The QA1 26 Series shock absorber features a 2-inch diameter zinc-plated steel monotube body, offering good corrosion resistance for various conditions. This particular shock has a 9-inch stroke, a compressed height of 15.4 inches, and an extended height of 24.63 inches, with eyelet connections at both the top and bottom. It's equipped with a 46mm piston, which helps provide good control over the vehicle's movement at different shaft speeds.

This monotube design is well-suited for a range of track environments, including rough dirt tracks and bumpy asphalt, making it a popular choice for modifieds, late models, and other racing classes. The hyperscrew configuration means it has a threaded port near the bearing end, sealed with a screw and O-ring to keep the nitrogen gas pressure contained. While the gas pressure in hyperscrew shocks is typically adjusted by QA1 or authorized rebuilders according to specific racing rules, shocks with a Schrader valve option allow for on-the-fly adjustments between races to adapt to changing track conditions.

QA1 shocks are known for being racer rebuildable and revalveable, allowing for consistent performance over time. Each unit is 100% dyno-tested and serialized in the USA to ensure it meets performance standards before it ships out.
