QA1 27A884M 27 Series Monotube Steel Shock 12.8/21.38 Stud/Poly IMCA Sealed

The QA1 27A884M is part of QA1's 27 Series — a stock mount monotube shock engineered specifically for circle track racing. Built with a zinc plated steel body and a 46mm hard anodized piston, the 27 Series delivers the proven performance of QA1's trusted 26 Series design while adding a stock mount configuration for broader compatibility.

This shock features a stud/polyurethane bushing (V) upper mount and a 4M linear valving tune, providing consistent, repeatable damping characteristics ideal for dirt and asphalt circle track applications. The IMCA Sealed designation means this unit is sealed at the factory to comply with IMCA (International Motor Contest Association) and many other sanctioning body rule packages that prohibit on-site revalving.

• Collapsed Length: 12.8 inches
• Extended Length: 21.38 inches
