Description
Premium 1:1 pulley kits feature 4-3/4" diameter pulleys with 1/2" wide grooves for use with industrial grade belts. The increased belt width helps reduce belt slippage when used with high performance mechanical fans. The small diameter pulley combination provides a 30% RPM reduction when using a power steering pump with a 6" pulley. Note: Pulleys are designed to use with short ŇCorvette StyleÓ 3/4" shaft water pump (ALL31105 or ALL31106).
