Shock Alum Twin Tube 7in Comp 3 Reb 5

The Shock Alum Twin Tube 7in Comp 3 Reb 5 from QA1 is a precision-engineered shock absorber designed for circle track racing and high-performance suspension applications. Built for drivers and teams who demand consistent damping performance lap after lap, this twin-tube shock delivers the responsiveness required in competitive oval track environments. Whether you're upgrading your existing suspension or building a complete race-ready setup, this aluminum shock provides the tuning flexibility and reliability that separates winning setups from the rest.

The twin-tube design utilizes a hydraulic compensator (Comp 3) to maintain consistent damping rates under thermal cycling, while the three-stage rebound valve (Reb 5) allows fine-tuned control of suspension movement on both bump and rebound. Constructed from black anodized aluminum, this 7-inch shock weighs just 4.2 lbs, reducing unsprung weight while maintaining structural integrity under extreme load conditions. The C3-R5 valve configuration provides the adjustability needed to dial in your vehicle's handling characteristics across varying track conditions, from qualifying runs to race day competition.

Circle track racers—including short-track stock car, sprint car, and modified competitors—benefit most from the precision tuning this shock delivers. Installation typically involves bolt-on mounting to your existing suspension geometry; verify your vehicle's shock eye specifications and mounting points before purchase. The 3.75 x 3.5-inch mounting footprint fits standard QA1 applications; consult your chassis builder or vehicle manufacturer to confirm compatibility with your specific frame and suspension design.
