NOTE: Special Order Item
Many of our customers have asked for crank pulleys that do not underdrive their alternators, power steering pumps, superchargers and water pumps. Because of these requests we developed our stock diameter crank pulleys. Many customers want the performance benefits of weight reduction without any sacrifices, especially audio enthusiasts as some audio competitions require voltage to remain at a specific level.
With our stock diameter crank pulleys the alternator and other accessories spin at stock speeds with NO underdrive. This is also important for stock or aftermarket supercharger systems. These systems are either driven off the alternator, air conditioning or power steering sections of the crank pulley and now you can use our stock diameter crank pulleys with these supercharger systems and have the same boost you had with the factory crank pulley.st level with the use of the factory diameter crank pulley.
100% of the power gains from the stock diameter pulleys comes only from weight reduction versus the factory crank pulley. The reduced weight allows for more power transfer to the drive wheels. Any of our accessory pulleys that are listed individually can be used in any combination with our stock diameter crank pulley or purchased as a set. The stock diameter crank pulleys are available in polished finish only.
