The QA1 26 Series is a one-piece monotube shock suited to a variety of track conditions and as a traction shock in many applications. It uses a 2 in. O.D. zinc-plated steel monotube body for corrosion resistance and is a popular choice for modifieds, late models, super stocks, and other classes. The 46mm piston supports car control at all shaft velocities, and deflective disc valving is available in linear, digressive, or linear/digressive form. The shocks are racer rebuildable and revalveable, made in the USA, and 100 percent dyno tested and serialized.
