The Elite series 250 amp alternator offers great output at idle RPM and excellent durability in a direct-bolt-in package. 6 phase technology, combined with massive twin rectifier assemblies and 12 diodes makes these alternators totally durable for daily use, while still maintaining great output at low RPM. These alternators will make 180 amps at engine idle speeds with a full 250 amp output at cruising speeds. This unit comes with an OEM diameter pulley, making it perfect for high RPM and racing use. NOTE: This unit may require a rectangle to oval adapter harness if your vehicle was equipped with the CS144 Heavy duty charging option from the factory. (this is not common) Ask a MechMan associate for assistance if you are unsure!

    Tony and the crew at MECHMAN are the best! My alternator in my 1999 Chevy Tahoe went and the cost to do a stock radiator had gotten to be almost as much as an updated alternator. After doing much research and speaking with Tony via email, I decided to go with MECHMAN. I am so happy I did. Tony and the Crew at MECHMAN answered all my questions and helped me out. The Alternator fit perfectly. Under their advice, I changed out the Idler Pulley and the Belt Tensioner. Little did I realize that GM changed the pulley diameter, increasing it, and so the stock belts no longer fit. I was able to find the right belt for the truck and the alternator goes an outstanding job. My altimeter in the truck reads between the first and second line after "14". I followed their instruction to the letter and it all came out well. The alternator is packaged in a good, stoudt box, and has everything you need. Wiring the alternator was a breeze. The pigtail was easy to hook into the underhood fuse panel for the ignition tap. The alternator runs smoothly and quietly. My truck now has all the power it needs for the accessories I want to install. I'm very happy. The overall transaction was fantastic. I highly recommend Tony and the Crew at MECHMAN. Their alternators are worth every penny! A+ 5*s. Thank you! I highly recommend.

    Tony was phenomenal. I had questions and sent an email. Not only was the response email sent back with speed. The answers were genuine because his response based on experience. Not a salesperson hiding behind a desk. A real technician. I made a decision based on his feedback and purchased a large case alternator. In less than 48 hrs it was in my possession. Seasoned and experienced staff to go with a product that’s raised and held the benchmark in the industry is a win win scenario. Like most car people this purchase was for the daily driver with durability in mind. I have no problem buying again for the project truck.
