QA1 27A953-9M 27 Series Monotube Shock Absorber Stud/T-Bar Sealed IMCA Legal 3-9M

The QA1 27A953-9M is a stock mount monotube shock absorber from QA1's 27A Series — the sealed, IMCA-legal variant of the proven 27 Series line. Sealed Hyperscrew (27A Series) shocks are IMCA Southern Sport Mod legal, with gas pressure that is only adjustable by QA1 or QA1 Authorized Rebuilders per sanctioning body and track rules, making them an ideal choice for competitors in regulated classes.

Key Features:

• Monotube steel construction with a zinc-plated body for corrosion resistance
• 46mm hard anodized piston for consistent, reliable damping
• Compressed length: 10.13 in. / Extended length: 15.67 in.
• Stud upper mount / T-Bar lower mount — stock mount design fits a wide range of circle track applications
• Valving: 3-9M — deflective disc valving with linear characteristics for a stable, predictable feel
• Sealed Hyperscrew (27A Series) — IMCA Southern Sport Mod legal; gas pressure sealed and only serviceable by QA1 or authorized rebuilders
• Linear valving provides a more stable car and allows the driver to better feel chassis feedback
• 100% dyno tested and serialized at the QA1 facility in Lakeville, MN
• Made in the USA

The 27 Series builds on the heritage of QA1's widely trusted 26 Series monotube shocks, adding a stock mount configuration to suit street stocks, hobby stocks, mini stocks, and other sanctioned classes that mandate stock mount shocks. The zinc-plated steel body resists the harsh conditions of dirt and asphalt racing environments alike.
