320 Amp alternator for Toyota / Lexus 4.3L

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 per Kw of power produced than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure long service life, even in severe conditions. Generally, the 240-amp model offers the best balance between peak output, and output at engine idle RPM. These 320-amp models will gain most of its extra power at vehicle driving RPMs for a more max effort amperage situation in a small case style fitment.

Installation Notes:

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