E Series

Newly redesigned for 2020, The Elite series offers the highest possible amperage and durability available in a large case alternator. 6 phase technology combined with massive twin rectifier assemblies and 12 diodes makes these alternators totally durable for daily use, while still maintaining 200+ amps at engine idle speeds.

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.


These alternators use the more robust 4 pin style regulator than the OE 2 pin ECU controlled alternator. There is no extreme voltage fluctuation as this will bypass the RVC charging system on all 2005> GM truck applications. Simply install the included 1 wire P101 harness to a tested 12v switched source and plug in the included P103 module into the vehicles 2 pin original alternator wiring harness. No check battery light, no computer-controlled voltage swings. The voltage you want, when you want it!
