QA1 8Q51 Twin Tube Shocks

When it comes to racing, every detail counts, and the QA1 8Q51 Twin Tube Shocks are designed with that in mind. These shocks deliver the performance and consistency that racers rely on while offering the tunability needed for various applications. Formerly known as the 82 series, the 8Q series features a compact aluminum small-body design that fits seamlessly into tight spaces.

Key Features

  • Rebuildable and re-valvable in minutes using basic tools and available kits.
  • The gland is equipped with relief cuts and a hyper screw port for easy filling and bleeding during assembly.
  • Upgraded seals effectively minimize leaks, especially in high-rebound situations.
  • Slip-fit design on the compression tube simplifies the rebuild process.
  • Laser-engraved, black-anodized closure nut ensures clear visibility of serial numbers and valving at the track or in the shop.
  • Compatible with QA1's steel small body shocks for coil-over configurations (kits sold separately).

Racers can easily tune the shocks using bleed shims or by drilling out bleeds, allowing for precise adjustments to match track conditions.
