Mechman S Series 320-Amp Racing Alternator for Cadillac STS - SRX

This listing includes:

• (1) Mechman 11046320 Standard Finish Alternator

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 diameter alternator pulley, and will require a slightly shorter drive belt for proper belt tension.

Please be aware that in some cases with a max effort 320-amp alternator in this application there may be low to no charging at vehicle idle RPM's. If this is a concern for your application, please use a 240-amp option with a larger battery bank.
