400 Amp high output billet alternator GM Trucks 2014+

The Elite series offers the highest possible amperage and durability available in a large case hairpin alternator. 6 phase technology combined with massive twin rectifier assemblies and 12 diodes make these alternators totally durable for daily use, while still maintaining great output. This alternator cranks out over 200 amps at engine idle speeds and a full 400+ at cruising speeds at FULL TEMPERATURE.

RVC Bybass Included! (GM: Remote Voltage Control)

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!

This modification will also simplify your battery cable wiring, as you will no longer need to run the battery ground cable through the OEM RVC sensor located on the original negative (ground) battery cable. This modification also makes the entire charging system work better, especially if you have multiple batteries installed

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. ((Check instructions section for finding belt sizes and wiring)). If you DO NOT use the correct shorter belt, this will result in very low to no output and create extra work load for the alternator.
