Info

This is Garage Sale priced because it has been mocked up and returned.  There are some dings and scratches from install.

Speedway Cast Aluminum double groove pulleys for Small Block Chevy feature a 20% reduction. Reduction pulleys have a smaller diameter which slows the speed of your fan, water pump, and alternator to reduce drag for more top-end horsepower. Plus, high RPM water pump operation is improved due to reduced fluid cavitation.

  • Machined from lightweight cast aluminum
  • Superior belt retention with extra-deep grooves
  • 20% reduction slows accessories down for less drag
  • Adds top-end horsepower
  • Reduces water pump impeller speed below cavitation threshold
  • Improved high-RPM cooling capabilities
  • 910-15482
    • 6-5/8" O.D.

Available for Short style pumps (55-68). Fits a 5/8" shaft.

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.
