Fan Spacer 1-1/2in

The Fan Spacer 1-1/2in from PERMA-COOL is a precision-engineered cooling system component designed to optimize radiator fan positioning and airflow efficiency in modern vehicles. Built for mechanics and enthusiasts who demand reliable thermal management, this universal spacer kit addresses a critical cooling system need: proper fan-to-radiator clearance that maximizes airflow while reducing unnecessary drag and parasitic load on the engine. Whether you're upgrading an existing cooling setup or fine-tuning a high-performance build, this spacer is essential for maintaining optimal operating temperatures under sustained driving conditions.

Manufactured from durable polished aluminum, the Fan Spacer 1-1/2in creates a precisely 1.5-inch separation between the fan assembly and the radiator core, preventing turbulent recirculation of hot air and improving overall cooling efficiency. The spacer accommodates 5/8-inch pilot fans and comes complete with all necessary bushings and mounting hardware, eliminating the need for sourcing additional fasteners. The polished aluminum construction resists corrosion while remaining lightweight at just 0.96 pounds, ensuring minimal impact on underhood weight distribution and reducing stress on engine fan clutches or electric motor assemblies over extended use.

This fan spacer benefits both street and off-road enthusiasts working on cooling system improvements, particularly those running tighter engine compartment layouts or aftermarket radiators that require precise fan positioning. Installation is straightforward for any mechanic with basic hand tools, and the universal design adapts to most fan mounting configurations. The 4 x 2 x 6-inch footprint integrates seamlessly into standard underhood spaces, making it ideal for hot rodders, truck builders, and anyone seeking measurable improvements in coolant temperature stability and fan blade longevity.
