What's in the Box

Speedway Billet Aluminum double groove pulleys for Small Block Chevy feature a 30% 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.

  • High strength billet aluminum construction
  • Superior belt retention with extra-deep grooves
  • 30% reduction slows accessories down for less drag
  • Adds top-end horsepower
  • Reduces water pump impeller speed below cavitation threshold
  • Improved high-RPM cooling capabilities

Fits a 5/8" shaft.

Part number 91015492 is the anodized black upper pulley only for the small block Chevy and available for either the short or long pump. The accompanying pulley for the lower in black is number 91015494 and again for the short or long pump. To finish the 30% reduction we offer the matched belts number 91015403. We also offer a package in a 20% reduction under part number 91015460 at an economical price. Not the same black pulley but in aluminum and it includes the upper, lower, and a set of belts.
