3″ Aluminum Crankshaft Pulley – M10

Product Description

Our 3″ 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).
