QA1 27A683-4M Monotube Shock Absorber 13.35" Compressed 22.55" Extended

The QA1 27A683-4M is a high-performance monotube shock absorber from the 27a Series, designed specifically for IMCA racing applications and other motorsports that require stock mount positions. This sealed shock features a large-body steel construction with a durable zinc-plated finish that resists corrosion while providing professional appearance.

Key Features:

• Monotube design with 46mm hard anodized aluminum piston for superior heat dissipation and consistent damping
• Steel body construction with protective zinc plating
• Compressed length: 13.35 inches / Extended length: 22.55 inches
• T-bar upper mount and polyurethane V-type lower mount configuration
• 3/4-inch mounting hardware included
• IMCA-legal sealed design for sanctioned racing
• Tuned valving optimized for performance applications

The 27 Series represents QA1's evolution of their proven 26 Series shock technology, incorporating the same reliable monotube performance with updated mounting configurations and improved durability. The monotube design provides more consistent damping characteristics compared to twin-tube shocks, making it ideal for racing applications where predictable handling is critical. The sealed construction ensures compliance with IMCA tech inspection requirements while the stock mounting positions allow for easy installation on compatible vehicles.
