HP Aluminum Water Pump 55-95 SBC 3/4 Pilot Hub

The HP Aluminum Water Pump 55-95 SBC 3/4 Pilot Hub is a high-performance mechanical cooling system component designed for small block Chevy engines that require reliable coolant circulation under sustained load. This pump is ideal for street, race, and work applications where factory cooling systems may not suffice.

Constructed from lightweight aluminum, this pump reduces rotating mass compared to traditional cast-iron options, which can help lower parasitic drag on the crankshaft. The mechanical design operates without electronic controls, providing simplicity and reliability in environments where electrical systems may be stressed.

Engine builders, restoration specialists, and weekend racers upgrading carbureted and early fuel-injected small block Chevys will find this pump essential for systems running higher coolant volumes. Its compact design allows for easy installation in tight engine bays without extensive modifications.
