## Overview

The Mechman Alternators 400 Amp RED Billet is a high-output, reliable alternator designed for 96-04 GM Trucks and SUVs. Featuring advanced 6-phase technology and dual rectifiers, it delivers over 200 amps at idle and exceeds 400 amps at driving speeds. Its compact 1.75-inch pulley requires a shorter belt for optimal tension, and the included H104 adapter harness ensures easy plug-and-play installation. Engineered for daily use, this alternator supports heavy electrical loads with robust performance.

## Description

The Elite Series 400 Amp Alternator is engineered to deliver exceptional amperage output and reliability. Featuring 6-phase technology and dual rectifier assemblies with 12 robust diodes, this alternator is designed for daily use and high performance. It produces over 200 amps at engine idle and exceeds 400 amps at cruising speeds (HOT RATED). This model includes a smaller diameter pulley, which typically requires a shorter belt (1/2 inch to 1 inch shorter than the original) for optimal belt tension. Installation Notes: For vehicles originally equipped with the CS144 heavy-duty charging system, an additional rectangle-to-oval adapter harness may be required (less common scenario). This alternator is a direct plug-in replacement for trucks equipped with the standard oval-shaped 4-pin plug, as depicted. BSTOCK

Review: Excellent quality - satisfied customer worked very well
Review: Do not buy! - Was very excited for this alternator. I even ordered the most expensive one so I could have the best experience. $700 is a lot of money for me. At first, I was very happy with it. Two years and a week later, right after my warranty expired, it stopped working. My battery was drained and I was left stranded in a parking lot. I replaced my battery thinking it was faulty, then realized it was the alternator. I contacted customer support asking for help since it was only a little over a week since the warranty expired, I just wanted to get it serviced/fixed since I spent so much on it, to go bad one year later is crazy. They would not help in any way. Since this, I have been replacing all the wires and connecters trying to get it to work. It will start sometimes and charge for a bit but then stops working. I’ve been left stranded 3 times now. I took good care or it during use, blowing it out with air every few months to keep it clean. I can’t understand why a product this expensive would be giving me only bad experiences. DO NOT BUY THIS PRODUCT. I would not recommend whatsoever!!! Stay away! Save your money.
