The QA1 27686-5M is a 27 Series stock mount monotube shock absorber featuring a zinc-plated steel body, 46mm hard-anodized piston, and linear Hyperscrew valving. Designed as a direct stock mount replacement, the 27 Series builds on the proven 26 Series platform while adding compatibility with factory shock mounts — making it a go-to choice for street stocks, hobby stocks, mini stocks, and other classes that require a stock mount shock.

Key Features:

• Stock Mount Design — Fits factory shock mounts without modification

• Zinc-Plated Steel Body — Corrosion-resistant finish for extended service life
• Linear Valving — 6C/5R — 6-click compression / 5-click rebound; provides a stable, predictable damping curve with complete control at low shaft speeds without creating excessive force at high shaft velocities

• Racer Revalveable & Rebuildable — Engineered for unparalleled repeatability; can be rebuilt and revalved to match changing track conditions
