Racing/Performance.

This 3" / 150mm billet aluminum crank pulley slows down the alternator and water pump by 45%, which frees up horsepower. These are machined to accept a crank fire trigger wheel (picture with red engine shows crank fire wheel installed). Note: We do not recommend the 3" pulley for street cars. (the 4" pulley is better-suited for street use, please see alternate listing for this ).
