QA1 5Q Series Twin Tube Steel Shocks – Rebuildable & Track-Ready.
The performance, consistency, and adjustment flexibility that racers need are delivered by QA1’s rebuildable twin tube shocks.
The 5Q Series, formerly known as the 51 and 53 series, is a large-body steel shock available in both stock mount and bearing mount configurations.
Depending on application and rules, choose from 7" and 9" bearing-mount bodies or a variety of stock-mount lengths.
For quick valving changes at the track, select models include rebound-adjustable piston rods.
Outstanding overall performance is achieved through precision details throughout the design.
A black zinc finish ensures a tight seal and consistency.
The scalloped base loop improves clearance in tight areas like mounts and control arms.
High-grade raw aluminum is used for pistons to minimize variations often found in anodized parts.
Bleed shims or custom-drilled bleeds can be used to valve shocks to meet specific performance needs.
