The QA1 Shock Alum Twin Tube 7-inch Comp 3 Reb 6 is a precision-engineered double-adjustable shock absorber designed for circle track racing applications. This aluminum-bodied unit delivers independent compression and rebound control through a C3 Compression / R6 Rebound valve configuration, enabling drivers to fine-tune suspension response across a wide range of track conditions.
The 7-inch stroke length suits mid-travel suspension geometries common in oval-track competition vehicles. The twin-tube design separates the damping circuit from the main piston chamber, a proven architecture that improves thermal stability and extends seal life during sustained high-speed cycling. The black anodized aluminum body resists corrosion while maintaining a lightweight profile—critical for vehicles where unsprung mass directly affects handling response and tire contact.
This shock is engineered for circle track racers—sprint cars, midgets, modified stock cars, and similar platforms where suspension tuning directly influences lap times and consistency. The adjustability range addresses the wide swings in track surface and weather that occur across a racing season. QA1 has established credibility in the circle track community through shock designs that balance performance and durability.
