Shock Alum Twin Tube 9in Comp 5 Reb 5

The QA1 Shock Alum Twin Tube 9in Comp 5 Reb 5 is a purpose-built twin-tube shock absorber engineered for circle track racing applications. This 9-inch aluminum shock features a C5 compression and R5 rebound valve configuration designed to manage suspension dynamics across varied track conditions, delivering controlled energy dissipation critical for competitive circle track performance.

At 4.8 lbs and finished in black anodized aluminum, this shock combines lightweight construction with corrosion resistance—essential for high-frequency cycling in racing environments. The twin-tube design separates compression and rebound damping, allowing independent tuning of each stroke. The C5-R5 valve rating indicates moderate compression response paired with controlled rebound, a common specification for circle track setups requiring responsive steering without excessive harshness. The 9-inch stroke length integrates with standard circle track suspension geometries and mounting points.

This shock is targeted at circle track racers—both short-track and oval racing—who demand precision suspension tuning for corner speed and consistency. QA1 manufactures shocks specifically for this racing segment, offering valve configurations that address the unique demands of banking, lateral load transfer, and sustained cornering. The aluminum construction and anodized finish provide durability through repeated wash cycles and extended track use.

For racers building or upgrading a circle track suspension package, shock selection determines how effectively the chassis responds to driver input and track surface changes. The QA1 6Q95 model sits in QA1's established line of circle track-specific dampers, recognized for consistent performance across multiple racing classes and track types.
