QA1® - 5Q Series Driver or Passenger Side Twin-Tube Shock Absorber

5Q Series Driver or Passenger Side Twin-Tube Shock Absorber by QA1®. Formerly known as 51 and 53 series shocks, the 5Q series is a large body steel shock. Small details add up to provide great overall performance. The black zinc coating ensures a very consistent finish, creating a tight seal every time. The scalloped base loop increases clearances in tight areas like upper control arms and shock mounts. Pistons are made of high-quality raw aluminum, minimizing variations that can be found in anodized parts. You can valve the shock with bleed shims or drill out bleeds to maximize tunability.
