QA1 276810-1M 27 Series Monotube Shock Absorber Large Steel 13.35/22.55 T-Bar/Poly V

The QA1 276810-1M is part of QA1's 27 Series — a stock-mount monotube shock absorber designed to deliver improved performance and durability over traditional twin-tube designs. Built with a zinc-plated steel body and a 46mm hard-anodized aluminum piston, this shock provides consistent damping force and long-lasting corrosion resistance in demanding conditions.

The 27 Series builds on the proven foundation of QA1's 26 Series, offering the same stock-mount compatibility with enhanced internal construction. The monotube design separates the oil and gas charge into distinct chambers, eliminating aeration and delivering more precise, fade-resistant damping — even under repeated hard use.

Key Features:

• Monotube design — single-tube construction for improved heat dissipation and consistent performance
• 46mm hard-anodized piston — larger piston diameter for superior damping control and durability
• Zinc-plated steel body — enhanced corrosion resistance for extended service life
• Stock mounting configuration — direct-fit replacement using factory mount locations
• T-Bar upper mount / Polyurethane V-style lower bushing — included hardware for secure, NVH-reducing installation
• Compressed length: 13.35 inches
• Extended length: 22.55 inches
• Multiple valving options available — tunable for street, performance, or race applications

The QA1 27 Series is an ideal upgrade for performance enthusiasts seeking a bolt-in monotube shock solution that retains OEM mounting compatibility while delivering measurably better ride control and handling precision.
