Fan Spacer 1in w/ Bolts

The Jones Racing Products Fan Spacer 1in w/ Bolts (WP-9104-FS1) is a precision aluminum component engineered for engine cooling system optimization in high-performance and racing applications. This 1-inch thick spacer arrives with all necessary hardware included, ready for immediate installation without additional fastener sourcing. The black anodized finish provides corrosion resistance and a professional appearance while protecting the aluminum substrate from oxidation during extended engine operation.

Fan spacers serve a critical function in cooling system architecture by creating additional clearance between the radiator fan and the engine block or radiator assembly. This increased spacing improves airflow efficiency and reduces parasitic drag on the engine, allowing the fan to operate more effectively during sustained high-RPM conditions. The aluminum construction balances weight savings against thermal stability—a key consideration for performance builds where every pound counts. The universal design accommodates a wide range of small-block and big-block configurations common in street and track engines, though installation verification with your specific vehicle's documentation is essential before purchase.

This spacer is ideal for builders upgrading cooling capacity, managing engine bay thermal dynamics, or optimizing fan performance in custom engines. Racers and high-output engine builders rely on fan spacer systems to maintain consistent coolant flow rates and prevent thermal cycling that reduces component life. The 0.5-pound weight and compact profile (4.25 x 2.65 x 6.2 inches) ensure minimal impact on engine bay packaging while delivering measurable improvements in radiator efficiency and fan blade loading characteristics.
