S Series 240 amp Alt for GM 3.6

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, 240, or 320 amp configurations. The 240 amp model offers the best balance between peak output, and output at engine idle RPM.

Installation Notes:

This unit comes equipped with a smaller 1.75 inch diamter alternator pulley, and will require a slightly shorter drive belt for proper belt tension.
