Mechman Elite Series 320 Amp Alternator For Select 3.6L And 3.0 GM 11252320

(1) Elite Series 320 Amp Alternator For Select 3.6L And 3.0 GM


The Elite series high output alternators offer 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 320+ at cruising speeds at FULL OPERATING TEMPERATURE. This alternator comes with a smaller diameter pulley installed on it and will require a 1/2" - 3/4" shorter 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!
