The QA1 27 Series is a stock-mount monotube shock that works like the 26 Series but adds a stock mount option. It features a zinc-plated body for corrosion resistance, a 46mm hard-anodized piston, and multiple valving options. The 27 Series is a popular choice for street stocks, hobby stocks, mini stocks, and other classes that require a stock-mount shock. Linear valving provides control at low shaft speeds without creating extreme forces at high shaft velocities and gives the driver a stable, predictable feel. The shocks are racer rebuildable and revalveable, made in the USA, and 100 percent dyno tested and serialized.
