The twin tube shocks from QA1 are rebuildable and offer the performance, consistency, and tunability that racers demand.
The 5Q series, formerly known as 51 and 53 series shocks, is a large body steel shock available in both stock mount and bearing mount configurations.
Choose from 7" and 9" bearing mount bodies or various lengths for stock mounts depending on rules and applications.
Shocks are available with rebound adjustable piston rods to adjust valving at the track.
Small details add up to create great overall performance.
The black zinc coating ensures a consistent finish, creating a tight seal every time.
The scalloped base loop increases clearances in tight areas like shock mounts and upper control arms.
High-quality raw aluminum is used for pistons, minimizing variations found in anodized parts.
You can valve the shock with bleed shims or drill out bleeds to maximize tunability.
Twin tube 2-1/16" big body diameter shock with eyelet bearing-mounts.
Racers can rebuild and re-valve their own shocks in a matter of minutes using basic tools.
Two-piece bodies make it simple to disassemble and reassemble shocks.
The gland features relief cuts and a hyper screw port, making shocks easy to fill and bleed on assembly.
An upgraded seal kit minimizes leaks, especially in high-rebound applications.
The compression tube uses a slip fit design to simplify the rebuild process.
5Q shocks utilize a laser-engraved, black-anodized closure nut to make serial numbers and valving easy to read at the track or in the shop.
QA1's steel body shocks can be used in coil-over configurations using the appropriate kits (sold separately).
