Metric Fan Spacer

The Metric Fan Spacer is a precision aluminum spacer designed for modern engine cooling systems, particularly V8 applications requiring metric-standard mounting interfaces. This hardware component solves a critical cooling efficiency problem: improper fan-to-radiator clearance reduces airflow and increases engine temperatures. Whether upgrading a Chevy V8 or Ford V8 cooling setup, the Metric Fan Spacer maintains optimal spacing and alignment, ensuring your cooling fan operates at peak efficiency while protecting against contact damage.

Constructed from clear anodized aluminum, this 2-inch thick spacer delivers corrosion resistance and a professional finish that withstands high-temperature engine bays without degradation. The anodized coating provides a protective barrier against oxidation, moisture, and thermal stress—essential for long-term reliability in demanding automotive environments. Included bushings and hardware eliminate the need for additional fasteners, simplifying installation and ensuring proper metric-thread compatibility. The compact footprint (4.65 x 2.25 x 7.95 inches) fits standard engine bay constraints while maintaining structural integrity under vibration and rotational loads.

This spacer is ideal for engine builders, performance enthusiasts, and restoration specialists working on Chevy V8 and Ford V8 platforms where cooling system optimization directly impacts reliability and horsepower. Installation is straightforward—position the spacer between the fan shroud and radiator, secure using the included hardware, and verify proper clearance before startup. For street engines, race builds, or high-output applications, the Metric Fan Spacer ensures consistent coolant circulation and eliminates fan-blade contact issues. Weighing just 0.67 lbs, it adds negligible mass while providing measurable thermal management improvement.
