320 Amp High Output Alternator For GM Truck 14-18

The 320 Amp High Output Alternator for GM Truck 14-18 is a custom-built alternator designed for reliable and efficient performance. With a standard build time of 2-3 weeks, this alternator is the perfect solution if you need a high-quality replacement for your GM truck.

Installation of this alternator is made easier with the included smaller 1.75 inch diameter alternator pulley. However, it is important to note that a slightly shorter drive belt is required for proper belt tension. Failure to use the correct shorter belt may result in low to no output and additional strain on the alternator.

The Elite series of alternators features a cast housing and is known for its exceptional amperage and durability. Equipped with 6 phase technology, massive twin rectifier assemblies, and 12 diodes, this alternator is built to withstand daily use while still providing excellent output. It produces over 200 amps at engine idle speeds and a full 320+ amps at cruising speeds, even at full temperature.

Unlike OE alternators, this unit uses a more robust 4 pin style regulator that bypasses the RVC charging system found in 2005 and later GM truck applications. This means there is no extreme voltage fluctuation, resulting in a stable voltage output. Installation is straightforward, with the included 1 wire P101 harness connecting to a tested 12v switched source and the P103 module plugging into the vehicle's original 2 pin alternator wiring harness.

The 320 Amp High Output Alternator is compatible with various GM trucks. It fits Cadillac Escalade 6.2L (2014-2019), Chevrolet Silverado 1500/2500/3500 all gas engines (2014-2018), Chevrolet Suburban all gas engines (2014-2018), Chevrolet Tahoe all gas engines (2014-2018), GMC Sierra 1500/2500/3500 4.3L/5.3L (2014-2018), GMC Sierra 1500/2500/3500 6.0L (2014-2016), GMC Sierra 1500/2500/3500 6.2L (2014-2018), GMC Sierra 2500/3500 6.6L Duramax (2014-2018), and GMC Yukon all gas engines (2014-2018).

Upgrade your GM truck's charging system with the 320 Amp High Output Alternator. With its exceptional power output and durability, it is the ideal choice for those seeking reliable and efficient performance.
