320 amp alternator for 4.0L Toyota / Lexus Truck

S Series

The S series of 6 phase alternators offers incredible output in a compact and durable package. 12 diodes, twin rectifier plates and outstanding airflow ensure long service life, even in severe conditions. While the 240-amp version offers the best balance between peak output, and output at engine idle RPM, this 320-amp version delivers that extra power at the vehicle driving/cruising RPM levels.

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.
