400A Large Case BILLET Hairpin Alternator For 2001-2007 GM Truck 6.6l Diesel - Side Output Stud - Black

The 400A Large Case BILLET Hairpin Alternator is specifically designed for 2001-2007 GM Trucks with a 6.6l Diesel engine. This alternator features a side output stud and comes in a sleek black color.

One of the standout features of this alternator is its custom-built nature. Most alternators are made to order, with a standard build time of 2-3 weeks. However, if you need an alternator sooner than that, we recommend contacting a sales associate to check if any in-stock options are available.

When it comes to installation, there are a few things to keep in mind. This unit comes equipped with a smaller 1.75 inch diameter alternator pulley, which means you will need a slightly shorter drive belt for proper belt tension. Additionally, it is important to note that this alternator is not recommended for sustained use above 5,000 RPM engine speed.

The Elite series 400 amp alternator offers impressive amperage output and durability at an affordable price. It utilizes 6 phase technology, along with massive twin rectifier assemblies and 12 huge diodes, to ensure its durability for daily use. This alternator is capable of producing 200+ amps at engine idle RPM and 400+ amps at cruising speeds, making it a reliable power source.

It is important to mention that, like most high output alternators, this unit comes with a smaller diameter pulley. Therefore, to ensure proper belt tension in most applications, you will need a 1/2 inch to one-inch shorter than stock length belt.

For installation, please note that if your vehicle was originally equipped with the CS144 Heavy duty charging option from the factory, you may require an additional rectangle to oval adapter harness. However, this is not a common requirement. In most cases, this unit is a direct plug-in for any truck originally equipped with the more common oval-shaped 4 pin plug.

Overall, the 400A Large Case BILLET Hairpin Alternator is a high-performance alternator that offers great amperage output, durability, and reliability. This product is designed to meet the specific needs of GM Trucks with a 6.6l Diesel engine, ensuring a seamless installation and efficient power supply for your vehicle.
