QA1 27683-5M 27 Series Monotube Shock Absorber Steel 13.35" Collapsed / 22.55" Extended T-Bar/Poly Valving

The QA1 27683-5M is part of QA1's 27 Series — a stock-mount, single-adjustable monotube shock absorber built for performance street and track applications. With a collapsed length of 13.35 inches and an extended length of 22.55 inches, this shock is engineered to deliver consistent, fade-resistant damping in a direct OEM-style mounting package.

The 27 Series builds on the proven foundation of QA1's popular 26 Series, adding a larger 46mm hard-anodized aluminum piston for improved heat dissipation and a more responsive damping feel. The zinc-plated steel body provides corrosion resistance and long-term durability in demanding environments.

Key Features:

• Monotube design — provides superior heat management and consistent damping compared to twin-tube shocks
• 46mm hard-anodized piston — larger bore for improved fluid flow and reduced fade
• Zinc-plated steel body — corrosion-resistant finish for extended service life
• Stock mount configuration — direct bolt-on replacement with no modifications required
• T-Bar / Polyurethane (Poly) valving — 3-5M — tuned valving for a balance of street comfort and performance handling
• Multiple valving options available — easily revalved to match specific vehicle weight and driving conditions
• Collapsed length: 13.35 in. | Extended length: 22.55 in.

Designed and manufactured in the USA by QA1 Precision Products, the 27 Series monotube shock is an ideal upgrade for enthusiasts seeking improved handling dynamics without sacrificing ride quality or requiring custom fabrication.
