370 Amp Black Billet Alternator For 14-18 GM Truck

The 370 Amp Black Billet Alternator is the perfect upgrade for your 2014-2018 GM truck. Designed with durability and high amperage in mind, this alternator is built to withstand daily use and provide optimal performance.

With a 1.75-inch diameter alternator pulley, this unit requires a slightly shorter drive belt for proper belt tension. Please note that sustained use above 5,000 RPM engine speed is not recommended with this alternator. To ensure maximum output and avoid unnecessary work on the alternator, it is crucial to use the correct shorter belt.

The Elite series of alternators has been newly redesigned for 2020, offering the highest possible amperage and durability. Equipped with 6 phase technology, massive twin rectifier assemblies, and 12 diodes, these alternators deliver over 200 amps at engine idle speeds.

Unlike OE 2 pin ECU controlled alternators, this alternator features a more robust 4 pin style regulator. This design eliminates extreme voltage fluctuations and bypasses the RVC charging system on all 2005 and newer 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 vehicle's original alternator wiring harness. No more check battery light or computer controlled voltage swings. You will get the voltage you want, when you want it!

The 370 Amp Black Billet Alternator is compatible with various GM truck models, including Cadillac Escalade, Chevrolet Full Size Truck/Silverado, Chevrolet Suburban, Chevrolet Tahoe/Full Size Blazer, GMC Full Size Truck/Sierra, and GMC Yukon. Please check the fitment list for exact engine sizes and years of compatibility.

Please note that most alternators are custom built to order, and the standard build time is 2-3 weeks. In case you need an alternator sooner than that, please contact one of our sales associates to check if any in-stock options are available.
