Crank Drv for Water Pump

The K.S.E. Racing crank drive for water pump (model KSD1011) is a precision-engineered component designed for high-performance engine builds where reliable coolant circulation is essential. This product is particularly suited for competition engines, street performance applications, and custom race motors, ensuring consistent flow and pressure to critical cooling passages.

This crankshaft-driven water pump pulley system interfaces directly with your crankshaft to transmit rotational force to the water pump with minimal slip and maximum efficiency. Its compact design (4.45 x 1.75 x 4.5 inches) and lightweight construction (0.81 lbs) help reduce parasitic load while providing the necessary mechanical advantage for effective cooling demands.

Engine builders, fabricators, and performance enthusiasts will find this component beneficial when assembling custom long-blocks, stroker packages, or standalone engine swaps, especially in scenarios where OEM cooling infrastructure may not suffice. Proper crankshaft hub compatibility and careful alignment during installation are crucial for optimal performance.
