400 Amp Red High Output Alternator 1996-2004 GM Truck 4.3L 4.8L 5.3L 5.7L 6.0L

The 400 Amp Red High Output Alternator is a top-of-the-line alternator designed for 1996-2004 GM trucks with 4.3L, 4.8L, 5.3L, 5.7L, and 6.0L engines. This alternator offers great amperage output and durability at an affordable price.

Featuring 6 phase technology, massive twin rectifier assemblies, and 12 huge diodes, this alternator is built to withstand daily use. It can produce 200+ amps at idle RPM and an impressive 400+ amps at cruising speeds, making it perfect for any high-demand electrical system.

Installation is straightforward, but it's important to note that this unit comes equipped with a smaller 1.75 inch diameter alternator pulley. As a result, it requires a slightly shorter drive belt for proper belt tension. Additionally, sustained use above 5,000 RPM engine speed is not recommended.

This alternator is a direct plug-in for any truck originally equipped with the more common oval-shaped 4 pin plug. However, if your vehicle was originally equipped with the CS144 Heavy Duty charging option, you may require an additional rectangle to oval adapter harness (this is not common).

The fitment guide for this alternator is extensive, covering various Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, and Pontiac models. From the 1996-2016 Chevrolet full-size trucks to the 1994-2004 GMC Safari, this alternator is compatible with a wide range of vehicles.

Please note that most alternators are 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 a sales associate to check if any in-stock options are available.

Upgrade your GM truck's electrical system with the 400 Amp Red High Output Alternator. With its impressive amperage output and durability, this alternator is the perfect choice for those who demand the best.
