  • Small Block Chevy Cast Alum. Long Pump Double Groove Lower Pulley
    Small Block Chevy Cast Alum. Long Pump Double Groove Lower Pulley
    (Part #91015488)
    x
                

    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.

    This is a 25% reduction pulley when used with the correct upper pulley, part number 91015476.

    • 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
    • 910-15488
      • 5-7/16" O.D.

    Available for long water pumps. 5/8" shaft.

    Note: The lower crank pulleys are manufactured thicker than normal stock pulleys.  This requires longer 3/8" bolts to be purchased separately.  Allen head type bolts recommended.

    KRC's adjustable idler - tensioner is used to keep proper belt tension and prevent belt slippage when using a mechanical fan. This can occur on both single drive belt and pulley systems that have a steering pump mounted of the front of an engine.

    KRC's idler tensioner is essential on dirt cars. Belt slippage can occur on cars that exceed 7,000 RPM and/or use a large or heavy fixed fan blade or a fan blade with a lot of pitch, which potentially causes overheating & pulleys to wear faster. This occurs on both single drive belt and pulley systems with a power steering pump mounted on the front of the engine. 

    Fan belts and pulleys work to slow down the fan. The belt slips because it is stretching to slow the fan. The belt heats up as the the the stretching increases. The only way to properly tension the belt is with an adjustable idler/tensioner. This keeps the engine running cooler because the belt is tighter. This will allow faster acceleration out of turns and harder braking on corners.
