QA1 26 Series Monotube Shock Absorber - 9in Stroke - Sealed Hyperscrew - 6-2 Valving - Steel

QA1 is well-known for making performance suspension components, and their 26 Series shock absorber is a solid choice for a variety of racing applications. This particular shock is designed as a traction shock, making it a popular option for modifieds, late models, and super stocks, especially on rough tracks or bumpy asphalt. It's built with a 2-inch diameter zinc-plated steel monotube body that resists corrosion, and this version features a sealed hyperscrew configuration, which is IMCA legal. The sealed hyperscrew design keeps the nitrogen gas pressure contained, and any adjustments to this pressure need to be done by QA1 or authorized rebuilders according to sanctioning body rules.

Inside, this shock uses a 46mm piston and deflective disc valving, specifically a 6-2 valving setup, which helps provide maximum car control across different shaft speeds. Because it's a monotube design, it helps keep the gas and oil separated, leading to more consistent performance. This shock is also designed to be rebuilt and revalved by racers, allowing for repeatable tuning to adapt to changing track conditions. It's made in the USA and each unit is dyno-tested and serialized to ensure it meets performance standards right out of the box.
