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.

    Fantastic alt. Mechman 400

    Posted by Jacob Wyatt on Oct 8th 2021

    Absolutely fantastic alt. Color looks great. Does overrated amps. Easy to install and wire. My only complaint is how short the stud is on the back of the alternator. My singer 390 I didn’t need a distribution block. Not a big deal to order one but would definitely like to seen them a little longer stud. For a high quality alt you can’t go wrong with mechman. Down4sound side of things I called to see if they had it in stock. The lady went to check and told me they did and was very helpful. Shipping was excellent. Great customer service as always. Thank y’all.
