Unorthodox Racing Pulley Sets are now available for the 2003+ Nissan 350Z and Infiniti G35. UR pulleys add close to 12HP on all Models. Horsepower increases are very noticeable due to the fact that UR pulleys primarily gain low-end torque. The main purpose of the underdrive pulley is to lose as much weight off the crank pulley, and turn that extra lost weight into HP Gains. Set Includes Crank Pulley, Alternator Pulley, Water Pump Pulley and 2 drive belts are included.
