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.

1949-53 Flathead Car Water Pump with Wide Belt
x
            Original Flathead water pumps have always suffered from unreliable bronze bushings and carbon seals. They almost always leaked and even Ford manuals warned mechanics not to tighten fan belts too tight. The excess slack allowed belts to slip and lose contact with the generator and water pump pulleys, causing more cooling and power problems. 

Speedway's completely new water pumps feature severe-duty roller and ball bearings, close tolerances and modular impellers to provide maximum flow and reduce cavitation. They also have modern ceramic seals on a heavy duty 5/8" shaft, making the assembly exceptionally strong and more efficient. Gaskets included.
