Belt Driven Race Fan 19in Alum Blade Silver

The Belt Driven Race Fan 19in Alum Blade Silver from FLEX-A-LITE is a mechanical cooling solution engineered for high-performance automotive applications where engine bay space, reliability, and thermal efficiency are non-negotiable. Unlike electric fans that draw parasitic power from your alternator and engine, a belt-driven fan couples directly to your engine's serpentine belt system, delivering consistent airflow proportional to engine speed. This design is preferred by serious builders and racers who demand maximum cooling capacity without electronic complexity or voltage-dependent performance variability.

Built with a 19-inch aluminum blade design, this race fan features six precision-molded blades optimized for high-volume air movement across your radiator core. The stainless steel hub assembly accepts a 5/8-inch pilot bore and accommodates bolt patterns ranging from 1-3/4 to 2-1/2 inches, ensuring compatibility across multiple cooling shroud configurations and frame designs. The natural finish steel hub paired with silver aluminum blades resists corrosion while maintaining the durability required in competition environments and extended high-RPM operation. At just 4.25 pounds, the fan minimizes rotating mass without sacrificing blade rigidity or aerodynamic efficiency.

This belt-driven fan is ideal for street rods, drag racing platforms, truck builds, and any custom engine swap where traditional electric cooling systems prove insufficient or incompatible. Installation requires a properly sized serpentine belt and compatible fan clutch or direct-drive pulley setup; verify your engine's accessory drive configuration and shroud dimensions against the fan's 18 x 3 x 20-inch envelope before purchase. Builders working with big-block applications, tight engine bays, or aggressive cooling demands will appreciate the consistent thermal output and mechanical simplicity that eliminates relay failures and thermostat sensor issues.
