QM Shock Aluminum QM2 3C-2R

The AFCO Racing Products QM Shock Aluminum QM2 3C-2R is a monotube racing shock designed for high-performance marine and offshore applications. Built with a 1.50-inch outside diameter aluminum body and blue anodized finish, this shock delivers responsive dampening across the full range of motion from 7.70 inches compressed to 10.20 inches extended. The threaded aluminum construction and C3-R2 valve configuration provide the tuning flexibility demanded by serious boaters and marine equipment specialists.

The QM2 shock's monotube design with adjustable valving allows fine-tuning of compression and rebound characteristics for specific hull types, water conditions, and operator preferences. The 3C-2R valve setup (three-circuit compression, two-circuit rebound) enables independent control of low-speed and high-speed compression events, critical for absorbing impact loads while maintaining ride control in varying sea states. The threaded design simplifies installation and adjustment without requiring specialized tools, making this shock suitable for both original equipment and retrofit applications on performance vessels.

This shock is engineered for serious boating enthusiasts—tournament anglers, offshore racing participants, and operators who demand precision handling in demanding marine environments. Weekend fishermen running open-center consoles and performance center console boats benefit from the controlled dampening across mid-range speeds, while professionals piloting competition or patrol vessels rely on the QM2's ability to manage extreme impacts from rough water conditions. The aluminum body resists salt corrosion better than steel alternatives, extending service life in harsh marine atmospheres.

AFCO Racing Products specializes in high-performance suspension components engineered for demanding environments. The QM2 represents the company's offshore and marine expertise, delivering the same precision tuning standards used in racing applications. At 1.25 pounds and compact dimensions (3.1 x 2.7 x 11.4 inches), the shock minimizes weight penalty while providing the shock travel and response characteristics needed for protected and open-water operations. This is specification-grade equipment for buyers who understand the difference between mass-market marine products and purpose-built performance components.
