E Series 370 Amp Billet 96-04 GM Truck

The E Series 370 Amp Billet 96-04 GM Truck alternator is a high-performance and durable option for your vehicle. With a newly redesigned model for 2020, this alternator offers the highest possible amperage and durability available in a large case alternator.

Equipped with 6 phase technology, massive twin rectifier assemblies, and 12 diodes, this alternator is designed to withstand daily use while still maintaining an impressive 200+ amps at engine idle speeds. It is built to provide maximum power and reliability for your GM truck.

Please note that this alternator is custom built to order, with a standard build time of 2-3 weeks. However, if you need an alternator sooner than that, you can contact our sales associates to see if any in-stock options are available.

Installation of this alternator is relatively straightforward, but there are a few important notes to keep in mind. The unit comes equipped with a smaller 1.75-inch diameter alternator pulley, requiring a slightly shorter drive belt for proper belt tension. It is also important to note that sustained use above 5,000 RPM engine speed is not recommended.

Before purchasing, please check the compatibility of this alternator with your specific GM truck model. It is compatible with various engines and years, such as the Buick Rainier (5.3, 04-06), Cadillac Escalade (5.7 / 6.0 / 6.2, 99-04), Chevrolet Avalanche (All Engines, 02-04), and many more. A full list of compatible models is provided for your reference.

For vehicles equipped with the HD charging option from the factory, a rectangle to oval adapter harness may be required. However, this is not a common requirement.
