Shock Steel Twin Tube 7in Comp 6 Reb 4

The QA1 Shock Steel Twin Tube 7-inch Compensator 6 Rebound 4 shock absorber is purpose-built for circle track racing applications where consistent damping and predictable handling are non-negotiable. This twin-tube design delivers the high-frequency response demanded by oval track competitors who rely on precise suspension tuning to maximize lap times and tire contact.

At 7 inches in length, this shock fits the geometric requirements of tight-geometry circle track chassis where space is constrained and suspension geometry is optimized for lateral acceleration. The C6-R4 valve configuration—6 compression and 4 rebound settings—allows tuners to dial in the precise balance between bump absorption and body control without excessive compliance that would rob cornering grip. The steel construction with black zinc coating provides durability against heat cycling and corrosion exposure typical in racing environments. Weighing 5.1 pounds, this shock minimizes unsprung mass while maintaining the structural integrity required for repeated load cycles.

Circle track racers—from asphalt modified competitors to dirt sprint car teams—select QA1 shocks for their ability to be tuned across a range of track conditions without requiring complete component swaps. The modular valve approach means adjusting compression and rebound damping is straightforward, supporting the rapid setup changes needed during practice sessions and between heat races. This shock is sold individually, so racers building a four-corner setup will need to order four units and specify damping preferences for each corner based on their suspension geometry and driver preference.
