QA1 26 Series Monotube Shock Absorber - 9in Stroke - Hyperscrew - 2-4 Valving - Steel

QA1 is known for making well-built suspension components for racing and performance applications. This 26 Series shock absorber is a great example, designed as a monotube unit that works well on a variety of track surfaces, whether you're dealing with rough dirt or bumpy asphalt. It's a popular choice for modifieds, late models, and super stocks, often used as a traction shock or for rough track conditions.

Constructed with a 2-inch O.D. zinc-plated steel body, this shock is built to resist corrosion. The hyperscrew design features a threaded port sealed with a screw and O-ring, keeping the nitrogen gas pressure contained. While the gas pressure in hyperscrew configurations is typically only adjustable by QA1 or authorized rebuilders according to specific racing rules, this setup ensures consistent performance. The 46mm piston is key to providing excellent car control across all shaft speeds, and the unit is racer rebuildable and revalveable, allowing for repeatable tuning. Each shock is made in the USA, 100% dyno-tested, and serialized to ensure peak performance right out of the box.
