Info

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

  • Upper Pulley Grooves:  Two
  • Lower Pulley Grooves:  Two 
  • Upper Pulley Diameter:  6-5/8" O.D.
  • Lower Pulley Diameter:  5-7/16" O.D.
  • Upper Pulley Snout Hole:  5/8" O.D. (can be drilled out to 3/4")

Fits Small Block Chevy V8 with '55-'68 short-style water pump 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.
