QA1 Precision Products Monotube Shock Absorber Hyperscrew

QA1 Precision Products Monotube Shock Absorbers with Hyperscrew are one-piece, gas-charged performance racing shocks. They suit a wide range of track conditions and work well as traction shocks. The zinc-plated steel monotube body resists corrosion. Racers use these shocks in modifieds, late models, super stocks and other circle track classes.

Key Features:

• Monotube construction: A single-tube, gas-charged design with deflective disc valving. Valving options are linear, digressive or linear/digressive.
• Hyperscrew design: A threaded round port near the bearing end of the shock body.
• Corrosion-resistant body: A 2-inch O.D. zinc-plated steel body.
• Racer rebuildable and revalveable: Built so you can service and tune the shock for repeatable performance.
• Multiple valving curves: A range of valving and gas-charging options lets you tune the shock to the track and your setup.
• Controlled damping: The damping curve gives control at low shaft speeds without creating extreme forces at high shaft velocities. Linear valving helps keep the car stable and lets the driver feel the car better.
• Made in the USA: Every QA1 shock is 100% dyno tested and serialized.

QA1 has been a name in high-performance suspension and driveline products since 1993. These shocks give racers a dependable, tunable option for dialing in handling.
