QA1 27688-4M 27 Series Monotube Shock Absorber Large Steel Body T-Bar/Poly V Valving

The QA1 27688-4M is a 27 Series stock-mount monotube shock absorber featuring a large steel body with a compressed length of 13.35 inches and an extended length of 22.55 inches. Designed as a direct-fit performance upgrade, this shock delivers consistent, race-proven damping in a bolt-in package compatible with OEM mounting locations.

The 27 Series builds on the proven architecture of QA1's 26 Series but introduces key upgrades, including a zinc-plated steel body and a 46mm hard-anodized aluminum piston for improved wear resistance and heat dissipation. The monotube design separates the oil and nitrogen gas charges, providing superior fade resistance and more consistent performance compared to twin-tube shocks.

Key Features:

• 27 Series stock-mount monotube shock design
• Zinc-plated steel body for corrosion resistance
• 46mm hard-anodized aluminum piston
• T-Bar / Poly V valving configuration (8-4M)
• Compressed length: 13.35 inches
• Extended length: 22.55 inches
• Multiple valving options available across the 27 Series lineup
• Monotube construction for consistent performance and fade resistance
• Stock mounting points for straightforward installation

The T-Bar/Poly V mounting configuration and 8-4M valving code make this shock a precise fit for specific performance street and track applications. QA1's monotube shocks are engineered and assembled in the USA, ensuring tight quality tolerances and reliable long-term performance.
