    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 short style pumps ('55-'68) or long style pumps ('69-'86). Fits a 5/8" shaft.
