The QA1 27A958M is a 27 Series stock mount monotube shock absorber built for circle track racing applications. Featuring a Stud/T-Bar mounting configuration, a collapsed length of 10.13 inches, and an extended length of 15.67 inches, this shock is valved at 8M (linear) and carries a sealed IMCA-legal designation, making it compliant with IMCA rule packages requiring sealed shocks.

Key Features:

• Stock mount monotube design — direct replacement fitment with race-proven monotube performance
• Zinc-plated steel body — provides corrosion resistance in demanding track environments
• 46mm hard anodized piston — delivers consistent, precise damping force
• Sealed IMCA-legal construction — meets the requirements of IMCA and other sanctioning bodies with sealed shock rules
• Stud/T-Bar mounting — upper stud mount and lower T-bar mount for broad application compatibility
• 8M linear valving — smooth, predictable damping response across the full stroke range
• Collapsed length: 10.13 in. | Extended length: 15.67 in. — precise dimensions for proper shock travel
• Deflective disc valving technology shared with QA1's trusted 26 Series platform

The QA1 27 Series builds on the proven performance of the 26 Series monotube shock while adding a stock mount option for racers who need a compliant, easy-to-install solution. The sealed hyperscrew design locks in nitrogen gas pressure, keeping valving consistent and race-day ready. Ideal for dirt and asphalt circle track classes running under IMCA or similar sealed-shock regulations.
