Mr. Gasket water pumps are built using all new components, not remanufactured. New cast iron housing with a custom impeller that can increase water flow by up to 30 percent. This in turn can reduce water temps by 20 degrees. The precision bearings and spin-balanced fan mounting hub also offer the ability to sustain higher RPMs than an off the shelf rebuild.

5.437 inch hub height with 5/8 inch pilot.
