The AFCO Racing Products Caliper GM Metric Aluminum 2.5-inch Piston is a precision-engineered braking component designed for high-performance marine and motorsport applications. This single-piston caliper features a forged aluminum construction with a 2.500-inch bore diameter and gray finish, delivering reliable stopping power in demanding operational environments. The 5.500-inch floating mount design provides superior brake balance and modulation—critical characteristics for vessels and vehicles operating in salt-water or extreme-duty conditions.
Forged aluminum construction offers a significant advantage in marine applications where corrosion resistance and weight savings matter. The metric bore specification ensures compatibility with metric brake line systems common in modern marine propulsion and towing equipment. The floating mount design reduces side loading on the rotor or brake disc, extending component life and maintaining consistent bite pressure across a range of operating temperatures. At 3.95 pounds per unit, this caliper maintains a lightweight profile without sacrificing structural integrity—a consideration for boats and performance watercraft where weight distribution affects fuel efficiency and handling.
This caliper is engineered for operators who demand OEM-quality components without premium pricing. Whether upgrading braking systems on offshore fishing vessels, high-speed center consoles, or specialized marine tow vehicles, the metric bore and aluminum construction provide proven durability across saltwater and freshwater environments. Serious boaters and offshore fishing operations recognize that brake system reliability is non-negotiable—failure in challenging water conditions creates safety risks that outboard replacement components cannot address.
AFCO Racing Products maintains a reputation for manufacturing OEM-quality brake and suspension components for the automotive aftermarket, marine, and motorsport sectors. Their engineering specifications align with industry standards for single-piston calipers in this bore class, making this component suitable for both original restoration and performance upgrade applications.
