Shock Street Stock Front Comp 3 Reb 8

The QA1 Shock Street Stock Front Compensator 3 Rebound 8 (part number 5Q933-8) is a high-performance twin-tube shock absorber engineered for circle track racing applications. This front-mounted unit combines QA1's proven 5Q series design with a C3-R8 tuning valve, delivering controlled damping characteristics optimized for oval track demands where consistent turn-in response and predictable suspension behavior are critical to lap times.

Built from steel construction with black zinc coating, this shock resists corrosion from track environment exposure and provides the durability required for sustained racing schedules. The twin-tube design offers improved heat dissipation compared to monotube alternatives, allowing the shock to maintain consistent performance across multiple heat cycles during qualifying and competition runs. The C3-R8 valve configuration manages both compression and rebound rates, with the 8-setting rebound tuning enabling fine-tuning of chassis balance across different track layouts and surface conditions. At 3.95 lbs per unit, the shock delivers responsive handling without excessive unsprung weight penalties.

This is a front shock for circle track racing—a category that demands purpose-built suspension geometry and damping curves. Racers preparing street stocks, modified classes, and oval track competition vehicles rely on QA1 components to achieve repeatable setup consistency lap to lap. Whether tuning for tight-turn tracks or higher-speed ovals, the adjustable rebound setting allows drivers and crew to dial in the suspension package without purchasing multiple shock units, reducing both downtime and development costs during a racing season.
