STOCK DIAMETER - STOCK BELT LAYOUT
“THE ORIGINAL", the first of their kind in the sport compact aftermarket. Many customers have asked for a crank pulley without underdrive. They want to keep the stock speed for their alternators, power steering pumps, superchargers and water pumps. UR developed this version because the performance benefits of weight reduction outweigh the need for underdrive, especially for audio enthusiasts as some audio competitions require voltage to remain at a specific level. Stock diameter is also important for factory or aftermarket superchargers. These superchargers need the stock diameter to keep the same boost you had with the factory crank pulley. The reduced weight allows more power transfer to the drive wheels. Any of our accessory pulleys (Accessory Pulleys – LINK) can be used in any combination with our stock diameter crank pulley or purchased as a set (Pulley Sets – LINK). So when you need a stock diameter crank pulley don’t settle for cheap imitators go with “THE ORIGINAL". These pulleys are only available in polished finish only.
