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 produced than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure long service life, even in severe conditions. 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 to be installed for proper belt tension.

    This was a great alternator for my 07 Sequoia! One thing to keep in mind, this is a SMALL case and you will lose amps at low RPM (even worse with 320). I chose this one over the larger one for my car audio application. I currently use both :)

  • Excellent Alternator

    I'm very happy with this alternator. It fits just like factory and produces the power I need to run my amps. The pulley is much smaller so you will need a shorter belt. I used a Gates K060878 (cross references to 07-09 Tundra 4.7) and it has the proper tension with no slippage. Voltage before was 13.3v hot idle, now I get 14.0v hot idle. Cruise is 14.3v. Worth every penny.
