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. The 240 amp model offers the best balance between peak output. and output at engine idle RPM.

NOTE: This alternator comes equipped with a 46mm diameter overdrive pulley that will require the installation a 1/2 inch to 1 inch shorter than stock length belt (not included) for proper belt tension.

    Super quick shipping time and my 2-3 weeks for build time was actually 1 week if that. Oh and when I reached out to see how my order was coming along I was met with quick respond from Jonathan Price. Everything installed no problem. Couldn’t be happier
