Description:
Specifically designed for short or Corvette water pumps, Allstar Performance aluminum reduction pulleys work with your power steering pulley and pump to provide a ratio within the GM-specified rpm range. Race engine rpm differs greatly from street engines. For 30 percent 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.
