Installation Notes:

This unit comes equipped with a smaller 1.75 inch diameter alternator pulley, and will require a slightly shorter drive belt for proper belt tension.  Not recommended for sustained use above 5,000 RPM engine speed.


The Elite series 320 amp HOT RATED alternator offers 200+ amp output at idle RPM, and excellent durability. 6 phase technology, combined with massive twin rectifier assemblies and 12 diodes makes these alternators totally durable for daily use, while still maintaining great output at low RPM. This alternator, (like most high output alternators) will come with a slightly smaller pulley on it and will require a slightly shorter belt to be installed for proper belt tension. Shorter belts are available and any local auto parts store.
