Shock Alum Twin Tube 7in Comp 3 Reb 6

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-R6 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. The C3 compression valve and R6 rebound valve enable three independently adjustable compression speeds and six rebound settings, allowing drivers to dial in front-end bite, mid-corner stability, and exit traction with precision unavailable in simpler dampers.

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 ease of adjustment with the damping sophistication required for competitive racing.

Sold individually. Verify mounting point compatibility and valve configuration against your vehicle's suspension design before purchase. This shock is a high-performance component intended for racing use and requires proper installation and setup for safe operation.
