QA1 27954-12M 27 Series Monotube Shock Absorber 10.13" Collapsed / 15.67" Extended Stud/T-Bar Mount

The QA1 27954-12M is part of QA1's 27 Series — a stock-mount, single-adjustable monotube shock designed for performance street and racing applications. With a 10.13-inch collapsed length and 15.67-inch extended length, this shock features a Stud/T-Bar (V) mounting configuration and 4-12M valving, offering a firm, performance-tuned damping profile right out of the box.

The 27 Series builds on the proven platform of QA1's popular 26 Series, delivering the same reliable stock-mount geometry in a heavy-duty steel body. The large-body design uses a 46mm hard-anodized piston for superior heat dissipation and consistent damping performance under repeated cycling. A zinc-plated body provides corrosion resistance for long service life in demanding environments.

Key Features:

• Monotube design for superior heat management and consistent damping
• 46mm hard-anodized piston for durability and reduced friction
• Zinc-plated steel body for corrosion resistance
• Collapsed length: 10.13 inches
• Extended length: 15.67 inches
• Mounting style: Stud/T-Bar (V) — stock replacement fitment
• Valving: 4-12M — performance-tuned compression and rebound
• Multiple valving options available across the 27 Series lineup
• Stock mount geometry for straightforward installation

QA1's 27 Series shocks are engineered for enthusiasts who want a meaningful performance upgrade over OEM dampers without requiring custom mounting hardware. The monotube construction separates the gas charge from the oil, eliminating aeration and maintaining predictable, fade-resistant performance on the street or track.
