QA1 27A686-3M 27 Series IMCA Sealed Monotube Shock Absorber T-Bar/Poly 6C/3R Valving

The QA1 27A686-3M is a stock-mount monotube shock absorber from QA1's 27 Series, purpose-built for circle track racing and IMCA-sanctioned competition. Engineered as an evolution of QA1's proven 26 Series platform, the 27 Series delivers the same trusted performance in a design that bolts directly into factory shock mounting locations.

Key Features:

• IMCA Legal / Sealed: Factory sealed and compliant with IMCA sanctioning body rules, ready for competition right out of the box
• 46mm Hard Anodized Piston: Oversized piston diameter provides rock-solid damping consistency and precise control lap after lap
• Zinc Plated Steel Body: Durable corrosion-resistant finish built to withstand the rigors of dirt and asphalt track environments
• Linear Valving – 6C/3R: 6-click compression and 3-click rebound linear valving for predictable, tunable handling balance
• T-Bar / Poly Mount: Features a T-bar upper mount and polyurethane bushing lower mount for compatibility with stock mounting hardware
• Monotube Design: Single-tube construction provides superior heat dissipation and more consistent damping performance compared to twin-tube designs
• Stock Mount Fitment: Designed to install in OEM shock mount locations — no chassis modifications required
• Collapsed / Extended Length: 13.35 in. collapsed / 22.55 in. extended
• 100% Dyno Tested & Serialized: Every unit is individually tested and serialized at the factory for verified, consistent performance
• Made in the USA

The QA1 27 Series monotube shock is the ideal choice for racers competing under IMCA rules who want a sealed, legal shock with a larger-diameter piston and linear valving. The 27A686-3M ships as a single shock absorber.
