QA1 27955-12M 27 Series Monotube Shock Absorber Steel Body Stud/T-Bar Mount

The QA1 27955-12M is part of the 27 Series — a stock-mount, monotube shock absorber designed as a high-performance upgrade over traditional twin-tube designs. With a 10.13-inch compressed length and 15.67-inch extended length, this shock features a stud/T-bar mounting configuration and is built for demanding performance and street applications.

The 27 Series builds on the proven foundation of QA1's 26 Series while introducing key improvements, including a zinc-plated steel body for corrosion resistance and a 46mm hard-anodized aluminum piston for enhanced durability and consistent performance. Monotube construction provides superior heat dissipation, reduced fade, and more precise damping response compared to conventional twin-tube shocks.

Key Features:

• Monotube shock design for superior heat management and fade resistance
• Zinc-plated steel body for long-lasting corrosion protection
• 46mm hard-anodized aluminum piston for durability and smooth operation
• Multiple valving options available (5-12M valving included)
• Stud/T-bar mounting — direct stock-mount replacement fitment
• Compressed length: 10.13 in. | Extended length: 15.67 in.
• Designed to work as a direct OEM-style replacement with performance-level damping

The QA1 27 Series shock is an ideal choice for enthusiasts seeking improved ride quality and handling over worn or stock shock absorbers, while maintaining factory mounting compatibility. Valving code 5-12M indicates the specific compression and rebound tune for this application.
