Shock Steel Twin Tube 9in Comp 8 Reb 2

The QA1 Shock Steel Twin Tube 9-inch Compensator 8 Rebound 2 is a purpose-built double-adjustable shock designed for circle track racing applications. This twin-tube shock delivers precise damping control through its C8-R2 (8-compression, 2-rebound) valve configuration, allowing drivers to dial in suspension response across a wide range of track conditions. The 9-inch stroke length and steel construction with black zinc coating provide durability under demanding racing loads while resisting corrosion from exposure to dirt, debris, and moisture common in racing environments.

The twin-tube design inherently separates the compression and rebound functions, enabling independent tuning of each phase. The 8-compression and 2-rebound valve settings offer a moderate compression resistance paired with minimal rebound damping—a configuration favored for tracks requiring quick shock response and reduced harshness. At 5.8 lbs per unit and measuring 19.2 inches in extended length, this shock integrates efficiently into racing suspensions without adding significant unsprung weight. The black zinc finish provides corrosion resistance while maintaining the clean aesthetic expected in competition vehicles.

Racers selecting circle track shocks prioritize consistency, predictable damping curves, and the ability to adjust stiffness without replacing the entire assembly. The QA1 twin-tube platform addresses these needs through its adjustable valving approach. This shock suits teams running sprint cars, late models, modified stock cars, and other circle track platforms where suspension geometry and spring rates are typically set, and shock damping becomes the primary tuning variable for optimizing grip and chassis balance across multiple configurations.

QA1 has established itself in the racing market as a manufacturer of adjustable shocks and suspension components used at every competitive level, from local short tracks to national touring series. The Shock Steel Twin Tube series delivers the performance and adjustability expected from a manufacturer with decades of racing-focused engineering.
