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. Not recommended for sustained use above 5,000 RPM engine speed.
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 200+ 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.

400 amp elite billet alternator
Absolutely love this alternator! I have a 99 Sierra with a stereo system and this thing is solid power. Tony at mechman answered a few questions I had and was very straightforward and direct. Yellow wire goes to a 12v ignition source. I used a fuse tap on my ignition E fuse in the fuse panel in engine bay. I also did a big 3 upgrade for both of my batteries with 0 gauge pure copper cables.
