MECHMAN | 400 AMP ORANGE BILLET ALTERNATOR FOR 14-18 GM TRUCK

E Series The Elite series 400 amp alternator offers great amperage output and durability at a great price. 6 phase technology, combined with massive twin rectifier assemblies and 12 huge diodes make these alternators totally durable for daily use. These impressive alternators produce 180+ at engine idle RPM and 400+ amps at cruising speeds HOT RATED. Like most high output alternators, this unit comes with a smaller diameter pulley, and will require a 1/2 inch to one inch shorter than stock length belt for proper belt tension in most applications. RVC Bypass: 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!

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.
