Machined aluminum crankshaft and water pump pulleys.Crank pulley diameter = 5 7/16 inches. Water pump pulley diameter = 6 5/8 inches.
Fits pumps with 5/8 shaft. Deep double grooves for improved belt retention. Includes two heavy duty belts. OTHER NOTES ABOUT THIS KIT.
Water pump pilot can be drilled to accept larger 3/4 pump shafts. Water pump pulley is normally drilled with both short and long style water pump bolt circle diameters so would work for either, but crankshaft pulley included will not line up if used on a short pump. This kit is usually used in race applications for slight HP gain and improved high RPM cooling - when used on street vehicles a larger alternator pulley may be needed to regain satisfactory charging.
