  • Allstar small block Chevy reduction pulleys are specifically designed for short or Corvette water pumps, pulleys work with power steering pump and pulley to provide a ratio within the GM specified RPM range. Race engine RPM differs greatly from street engines. For 30% less water pump speed and reduced weight and inertia, the crankshaft and water pump pulleys are smaller in diameter than standard reduction pulleys. Acceleration capabilities are greatly enhanced.
    Note: Crankshaft pulley will work with either water pump pulley without spacers.

    Some parts are not legal for use in California or other states with similar laws / regulations
