Crank and water pump pulley kit
Premium 1:1 pulley kits feature 4-3/4 in. diameter pulleys with 1/2 in. wide grooves for use with industrial grade belts. The increased belt width helps reduce belt slippage when used with high performance mechanical fans.
Note: Pulleys are designed to use with short "Corvette Style" 3/4" shaft water pump (ALL31105 or ALL31106).
