QA1 27686-10M 27 Series Monotube Stock Mount Shock Absorber 6C/10R Linear Hyperscrew

The QA1 27686-10M is part of the 27 Series — a stock mount monotube shock absorber engineered for circle track racing applications including street stocks, hobby stocks, and mini stocks. Built on the proven platform of QA1's 26 Series, the 27 Series brings that same performance DNA into a stock mount-compatible package, making it an ideal upgrade for classes that require OEM-style mounting.

This shock features a 6 compression / 10 rebound (6C/10R) linear valving configuration with a Hyperscrew adjuster, delivering a damping curve that provides complete control of suspension at low shaft speeds without generating extreme forces at high shaft velocities. Linear valving produces a more stable, predictable feel that helps the driver better sense the car's behavior at the limit.

Key Features:

• Stock mount monotube design — fits OEM shock locations without modification
• 46mm hard anodized piston for rock-solid control and long-term durability
• Zinc plated body for corrosion resistance
• Linear valving with Hyperscrew adjustment for consistent, repeatable damping
• Multiple off-the-shelf valving options available across the 27 Series lineup
• Racer revalveable and rebuildable for tuning flexibility
• 100% dyno tested and serialized for quality assurance
• Made in the USA

The 27686-10M also pairs with the 27A Series (Sealed Hyperscrew) variant for IMCA Southern Sport Mod legal applications. Whether you're building a competitive circle track car or refreshing a performance street machine, the QA1 27 Series delivers the consistency and tunability racers depend on.
