QA1 5Q Series Twin Tube Steel Shocks – Rebuildable & Track-Ready.
The performance, consistency, and adjustability that racers rely on are delivered by QA1’s rebuildable twin tube shocks.
The 5Q Series, previously known as the 51 and 53 series, is a large body steel shock available in both bearing mount and stock mount configurations.
Choose from 7" and 9" bearing-mount bodies or a variety of stock-mount lengths based on your rules and setup.
Select models feature rebound-adjustable piston rods for quick, trackside valving changes.
Performance across the board is enhanced by attention to detail.
A consistent finish and tight seal are ensured by a black zinc coating.
The scalloped base loop improves clearance in tight-fitting areas like control arms and shock mounts.
Inconsistencies often found in anodized parts are reduced by high-grade raw aluminum pistons.
Bleed shims or modified bleeds can valve shocks to meet your specific performance needs.
