S Series

The S series of 6 phase alternators offers incredible output in a compact and durable package. Highly efficient, these units use less horsepower than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure long service life, even in severe conditions. These units are available for a broad range of domestic and import applications in 170, or 240amp configurations. This unit features an OEM 2.6" diameter pulley, making it great for racing applications using the stock diameter crankshaft pulley.  If changes have been made to the diameter of the crankshaft pulley on the engine, please contact a sales associate for assistance with calculating pulley ratio.
