This water pump-to-fan centering bushing is designed to convert a water pump with a 5/8” centering spud up to ¾” to fit popular aftermarket fan spacers.

This bushing ensures the fan and fan spacer are hub centric with the water pump to reduce any imbalance due to improper alignment of the components with respect to the pump.

All Gorsuch Performance Solutions fans have a 5/8” centering bore and should bolt directly to most fan spacers without the need for this reducer bushing, but customers who use a non-performance or stock-type water pump may find this helpful.

Dimensions: 3/4" to 5/8" x 1/2" Long
