Info

Combo includes cast aluminum double-groove aluminum water pump pulley, crank pulley, and matched pair of heavy duty belts. Slows water pump speed by 20% for increased horsepower.

For Small Block Chevy V8s with '69-'86 long style water pumps with 5/8" shaft.

Note: The lower crank pulleys in our combo kits are manufactured thicker than normal stock pulleys.  This requires longer 3/8" bolts to be purchased separately.  Allen head type bolts recommended.

Get the correct pulleys for your application by learning which water pump you have as explained in our tech article. SBC - Short vs Long Water Pump
