Shock Alum Twin Tube 7in Comp 5 Reb 3

The QA1 Shock Alum Twin Tube 7-inch Compensator 5 Rebound 3 (model 6Q75-3) is a high-performance monotube shock absorber engineered for circle track racing and short-course off-road competition. This aluminum twin-tube design delivers controlled suspension response across varied terrain and track conditions, with a 7-inch stroke length and carefully calibrated rebound damping to manage weight transfer and maintain chassis stability through corners and over rough surfaces.

The 5 compression and 3 rebound damping configuration represents a moderate-stiffness tuning suited to dirt track and short-course vehicles that demand predictable suspension geometry without excessive harshness. The aluminum construction minimizes unsprung weight while maintaining structural rigidity under repeated shock cycles. At 4.2 lbs and measuring 19.1 inches in overall length, this shock is compact enough for tight installation bays while providing the extended stroke necessary for dramatic vertical travel. The twin-tube design separates the main piston chamber from the reserve chamber, improving heat dissipation and consistency during extended racing runs.

QA1 shocks are purpose-built for drivers and teams focused on precise suspension tuning in competitive environments. The Shock Alum Twin Tube 7in Comp 5 Reb 3 serves racers, off-road competitors, and suspension builders who prioritize repeatability and adjustability. This shock pairs well with matched suspension geometry and complements cost-effective race programs where damping tuning can be performed without breaking down the shock itself. Whether you're dialing in a circle track car or refining an off-road short-course setup, this shock offers field-proven performance at a competitive price point.
