Tap into hidden horsepower with the ZERONE Lightened Crank Pulley. Developed exactly to the stock diameter to keep the stock speed for the alternator, supercharger and water pump. 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. The big weight loss gets you a lot more power to the wheels. Each pound of weight removed from the crankshaft is worth approximately 2.7HP and gains even more with forced induction, nitrous and VTEC.
All ZERONE Lightened Crank Pulleys are made of T6 6061 aluminium and comes in gold anodized finish.
