Shock Steel Twin Tube 7in Comp 5 Reb 3

The QA1 Shock Steel Twin Tube 7-inch Compensator 5 Rebound 3 shock absorber is a purpose-built component for circle track racing applications. This twin-tube design delivers precise dampening control through a C5 compression and R3 rebound valve configuration, engineered to maintain consistent suspension geometry through high-speed cornering and load transfers inherent to oval track competition.

At 7 inches in length, this QA1 5Q75-3 shock fits within the dimensional constraints of most circle track chassis while providing the stroke necessary for effective bump absorption and rebound control. The steel construction with black zinc coating provides corrosion resistance in high-humidity and splash environments. The twin-tube architecture separates the main piston rod from the reserve tube, allowing independent control of compression and rebound forces—critical for tuning a race car's balance through different track surfaces and banking angles.

This shock is specified for drivers and teams focused on short-track oval racing where suspension responsiveness directly impacts corner speed and stability. The valving package (C5-R3) balances energy dissipation on compression with smooth rebound action, reducing harshness on bump compliance while minimizing bottoming on heavy braking zones. QA1's track-proven engineering makes this unit a core suspension component for competitive circle track programs operating under strict rule packages that demand reliability and adjustability.

Each shock is sold individually; pairs are required for complete suspension installation. Verify mounting points and dimensions against your chassis specifications before purchasing to ensure proper fitment and performance.
