What's in the Box

Info

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.
