Description
QA1’s rebuildable twin tube shocks offer the performance, consistency, and tunability racers demand.
Formerly known as 51 and 53 series shocks, the 5Q 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 various stock mounted lengths depending on rules and applications. Shocks are also available with rebound adjustable piston rods to adjust valving at the track.
Small details add up to provide great overall performance:
- Black zinc coating ensures a consistent finish and tight seal every time
- Scalloped base loop increases clearances in tight areas like upper control arms and shock mounts
- High-quality raw aluminum pistons minimize variations found in anodized parts
- Valve the shock with bleed shims or drill out bleeds to maximize tunability
- 5Q shocks can be re-valved and rebuilt by racers in minutes using basic tools
- Two-piece bodies simplify disassembly and reassembly
- Gland features relief cuts and hyper screw port for easy filling and bleeding
- Upgraded seal kit reduces leaks, especially in high-rebound applications
- Slip-fit compression tube simplifies the rebuild process
- Laser-engraved black-anodized closure nut makes serial numbers and valving easy to read
QA1’s steel body shocks can be used in coil-over configurations with the appropriate kits (sold separately). Racers can rebuild and re-valve their shocks using available tuning and rebuild kits.
