QA1 27684-7M 27 Series Stock Mount Monotube Shock Absorber Linear Hyperscrew

The QA1 27684-7M is part of the 27 Series — a stock mount monotube shock absorber built for circle track competitors who need OEM-style mounting with race-proven monotube performance. Designed as a natural evolution of QA1's trusted 26 Series, the 27 Series delivers the same core performance characteristics in a package engineered to fit factory shock mount locations.

Key Features:

• Stock Mount Design: Fits factory shock mount locations — ideal for street stocks, hobby stocks, mini stocks, and classes requiring stock mount shocks
• 46mm Hard Anodized Piston: Larger piston diameter provides rock-solid damping control and long-term durability
• Zinc Plated Body: Corrosion-resistant finish extends service life in demanding racing environments
• Linear Valving (Hyperscrew): Delivers a more stable and predictable handling feel, allowing the driver to sense suspension movement more accurately
• Controlled Damping Curve: Optimized for complete suspension control at low shaft speeds without generating extreme forces at high shaft velocities
• Racer Revalveable & Rebuildable: End users can rebuild and revalve the shock to suit changing track conditions or driving styles
• 100% Dyno Tested & Serialized: Every unit is individually tested and serialized for traceability and unparalleled consistency
• Made in the USA

Also available in the 27A Series with a Sealed Hyperscrew configuration (IMCA Southern Sport Mod legal). The 27684-7M is a popular choice for racers competing in classes that mandate stock mount shock absorbers, offering a direct upgrade path with proven QA1 monotube technology.
