Q & A

What's in the Box

Kit includes a cast aluminum double groove water pump pulley and double groove crank pulley, and a matched pair of heavy duty belts. Has a 1:1 water pump/crankshaft speed ratio.

Fits Small Block Chevy V8 with '55-'68 short-style water pump with either a 5/8" or 3/4" 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
