QA1 276812-4M 27 Series Monotube Shock Absorber 13.35 Collapsed 22.55 Extended T-Bar/Poly Mount

The QA1 276812-4M is part of the 27 Series Stock Mount Monotube Shock lineup — a modern evolution of QA1's proven 26 Series design, now offering stock-mount compatibility for street and performance applications. With a collapsed length of 13.35 inches and an extended length of 22.55 inches, this shock features a T-Bar upper mount and polyurethane bushing lower mount for direct, stock-location fitment.

Key Features:

• Monotube design for improved heat dissipation and consistent damping performance
• Zinc-plated steel body for corrosion resistance and long service life
• 46mm hard-anodized piston for precise valving and durability
• 12/4 valving (12 compression / 4 rebound) for a firm, performance-tuned damping profile
• T-Bar upper mount with polyurethane bushing lower loop mount
• Collapsed length: 13.35 in. | Extended length: 22.55 in.
• Stock ride height compatible — direct bolt-in installation
• Linear valving characteristic for predictable, consistent response

The QA1 27 Series monotube shock delivers race-derived damping technology in a stock-mount package, making it an ideal upgrade for performance street driving, circle track, and oval racing applications. The 12/4 valving code provides stiffer compression damping relative to rebound, suited for vehicles that benefit from controlled body roll and reduced dive under braking.
