Fan Spacer Kit 1.50

The Fan Spacer Kit 1.50 from ALLSTAR PERFORMANCE is an essential cooling system component designed for engine builders, performance enthusiasts, and mechanics upgrading Chevy V8 and Ford V8 platforms. This 1.5-inch aluminum spacer kit solves a critical thermal management problem: when high-flow water pumps or low-profile radiators are installed during engine modifications, the factory fan blade often sits too close to the radiator core, reducing airflow efficiency and causing cooling system bottlenecks. By creating proper spacing between the fan and radiator, this kit restores optimal air circulation through the cooling core.

Constructed from black anodized aluminum, the Fan Spacer Kit 1.50 provides structural rigidity while resisting corrosion in the engine bay environment. The kit includes all necessary bushings and mounting hardware for direct installation between the fan hub and water pump pulley, ensuring proper alignment and load distribution. The 1.50-inch thickness is the critical measurement—it's precisely engineered to match common radiator setups and replacement cooling packages found in street and race applications. Anodized finish protects against oxidation and extends the lifespan of the spacer in high-temperature conditions.

Mechanics and engine builders benefit most when installing aftermarket water pumps, aluminum radiators, or electric fan conversions where factory dimensions no longer align. The fan spacer kit is compatible with both Chevy V8 and Ford V8 engines, making it versatile across domestic platform swaps and restorations. Installation requires no special tools—simply remove the fan, install the spacer with included hardware onto the water pump shaft, and reinstall the fan assembly. This straightforward modification improves cooling efficiency, prevents fan-to-radiator contact, and reduces parasitic drag on the engine, resulting in more reliable operation during sustained driving or competition.
