MECHMAN | S SERIES 320 AMP ALTERNATOR FOR TOYOTA

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:
1. 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.
2. While this 320-amp alternator does make more power than our 240-amp offering, in some applications it may cause a low to no voltage output at idle. We always recommend our 240-amp version for 95% of customers.
3. If your vehicle does have a low or stock idle (400-600rpms), the 240 amp version is most likely your better option. If you do not mind moving your idle up <200 rpms> or so or can rev the vehicle up while stopped the 320 create more power. It all comes down to personal preference for the customers application.
