370z Unorthodox Racing Lightweight Crank Pulley with Belt, Stock Sized

Unorthodox Racing Stock Sized pulleys are now available for the Nissan Z and Infiniti G Cars.. The main purpose of the stock sized pulley is to lose as much weight off the crank pulley, and turn that extra lost weight into HP Gains. These do not underdrive the accessories, and work great with superchargers or competition stereos. Pulley and Belt Included.
