QA1 27686-9M 27 Series Monotube Shock 13.35in-22.55in T-Bar/Poly Linear 6C/9R

The QA1 27686-9M is a 27 Series stock-mount monotube shock absorber designed for GM mid and full-size applications. Built as a direct replacement for factory shock mounts, the 27 Series delivers race-proven monotube performance in a bolt-in package — no modifications required.

Key Features:

• Stock Mount Design: Fits OEM shock mount locations for straightforward installation without fabrication
• 46mm Hard-Anodized Piston: Larger diameter piston delivers rock-solid damping control and long-term durability
• Zinc-Plated Steel Body: Corrosion-resistant finish protects against the elements for extended service life
• Linear Valving — 6 Compression / 9 Rebound: Deflective disc valving tuned for balanced, consistent performance across a wide range of driving conditions
• Hyperscrew Gas Valve: Sealed nitrogen pressurization maintains consistent damping force and prevents cavitation
• Compressed Length: 13.35 inches | Extended Length: 22.55 inches
• Upper Mount: T-Bar | Lower Mount: Polyurethane Bushing
• 100% Dyno Tested & Serialized: Every shock is individually tested and serialized before leaving the factory
• Made in the USA

The 27 Series builds on the legacy of QA1's trusted 26 Series race shocks, bringing the same high-performance monotube construction to stock mounting applications. Multiple valving options are available across the 27 Series lineup, allowing builders and tuners to select the precise compression and rebound characteristics their application demands. Backed by a QA1 limited warranty.
