E Series

The Elite series 400 amp alternator offers great amperage output and durability at a great price. 6 phase technology, combined with massive twin rectifier assemblies and 12 huge diodes make these alternators totally durable for daily use. These impressive alternators produce 220+ at engine idle RPM and 400+ amps at cruising speeds HOT RATED. Like most high output alternators, this unit comes with a smaller diameter pulley, and will require a 1/2 inch to one inch shorter than stock length belt for proper belt tension in most applications. Installation Notes: This unit may require an additional rectangle to oval adapter harness if the vehicle was originally equipped with the CS144 Heavy duty charging option from the factory. (this is not common) This unit is a direct plug in for any truck originally equipped with the more common oval shaped 4 pin plug as shown.

 

Installation Notes:

This unit comes equipped with a smaller 1.75 inch diameter alternator pulley, and will require a slightly shorter drive belt for proper belt tension.

This unit may require a rectangle to oval adapter harness if the vehicle is equipped with the HD charging option from the factory. (not common)

The customer service is world-class!  Zack and his team were super responsive and went out of their way to research and come up with some creative solutions!  The product selection, prices and shipping are some of the best you’ll find anywhere online.  Plus the fitment and ease-of-installation of their products are excellent.

The last 3 box designs I've purchase were all 150+ db certified in the lanes, your results may vary depending on vehicle and power but they definitely know what they're doing. Well worth the money !
