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 a top-of-the-line alternator specifically designed for 2001-2007 GM Trucks with a 6.6l Diesel engine. This high-performance alternator features a side output stud and comes in a sleek black color, adding a touch of style to your engine.

One of the standout features of this alternator is its custom-built nature. While most alternators are made to order with a standard build time of 2-3 weeks, we understand that sometimes you need an alternator sooner than that. That's why we recommend contacting a sales associate to check for any in-stock options that can be delivered to you more quickly.

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, ensuring 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 for your vehicle.

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. Designed specifically for GM Trucks with a 6.6l Diesel engine, this alternator ensures a seamless installation and efficient power supply for your vehicle, giving you peace of mind while on the road.
