QA1 27A954-10M 27 Series Monotube Stock Mount Shock Absorber Stud/T-Bar IMCA Sealed

The QA1 27A954-10M is a 27A Series large steel monotube shock absorber built for circle track racing. Featuring a compressed height of 10.13 inches and an extended height of 15.67 inches, this shock uses a stud top mount and T-bar bottom mount configuration with 10M linear valving. As part of the 27A Series, it is equipped with a Sealed Hyperscrew, making it legal for IMCA-sanctioned competition including IMCA Southern Sport Mod classes.

Key Features:

• Monotube design with zinc-plated steel body for corrosion resistance
• 46mm hard anodized piston for consistent, durable damping performance
• Sealed Hyperscrew (27A Series) — gas pressure adjustable only by QA1 and QA1 Authorized Rebuilders per IMCA sanctioning body and track rules
• 10M linear valving — provides a stable, predictable damping curve for improved driver feedback
• Stud upper / T-bar lower mount — stock mount configuration for direct-fit installation
• Damping curve engineered for complete control at low shaft speeds without generating extreme forces at high shaft velocities
• Racer revalveable and rebuildable by QA1 Authorized Service Centers for long-term serviceability
• Popular choice for street stocks, hobby stocks, mini stocks, and other classes requiring a stock mount shock

The 27A Series builds on QA1's proven 26 Series platform, adding a stock mount option that makes it a natural fit for IMCA-legal dirt and asphalt circle track applications. Linear valving delivers a more stable handling balance and allows the driver to better sense chassis behavior throughout the corner.
