Let me start by stating that anyone rating this company less than five makes absolutely no since whatsoever. I just picked up the alternator and it is amazing. The quality and craftsmanship is superior. They take the time to explain everything in detail. Very professional and polite. Now it’s time to install this amazing piece of machinery. Thanks DC.

Anthony was totally awesome in his customer service! Thanks for the speed, kindness, and knowledge! 370A alternator installed: a great improvement from the 165A stock and the prior 215A (max that napa would sell). Thanks, Dr H / Bruce

I purchased a 270 amp XP alternator directly from DC Power Inc. in May 2019. After 16 months of powering a 3000 watt audio system with dual batteries its still performing exceptionally. From the order date until it arrived was 7 weeks. I emailed them a couple of times to check on the status of the order and received a response within a day or two. I was okay with the wait time since I was told by email the alternator was made to order. I have measured the DC amperage and voltage with Klein Amp meter, both meet the specifications advertised. The only complaint I have is the pulley wheel was machined very thin on the inside half. I have attached a photo of the alternator after 16 months of use. Well built (besides pulley wheel), still works well, smooth transaction, and meets specifications.

I received my alternator with a pulley too big. I called and spoke to Anthony and he shipped me the correct size then and there with overnight shipping. I’ve yet to install the alternator but based on their history, I trust it. Customer service is great, I’d recommend them.

I purchased a DC Power Engineering XP270 for my Scion XB in 2012 and I got the alternator and it was beautiful there was a lil problem something was out of alignment inside do to ruff shipment( thanks UPS ). They promptly sent me a return label and it was off and got fixed and was back in a jiffy in excellent sharp, I installed it and it was unknown at the time that the solid pulleys when installed on the brand new 2012 scion XB did not play well lol 3 AC compressors later and an angry Toyota reluctant warranty replacements’. I talking with DC engineering and talking with Toyota we discovered it needed a decoupler pulley to take belt noise out of the serpentine system, and wala that fixed everything DC engineering promptly sent me the correct pulley. Then tragedy struck my brand new car was T-boned and totaled I had pulled the alt out just days before the accident and put the stock one back in as my car was going in for service and Toyota want all OEM parts in it for services so I obliged well death to my car but it deployed all the air bags and I had minor bruises and scrapes. I immediately purchased another 2012 scion XB and my wonderful Alt sat in its box for 7 years as I was crippled my debut and could not afford to finish out my Audiophile build and did not reinstall my DC alternator with its now correct pulley. 7 years later and a motor cycle wreak settlement later I am finally out from under all my debut and I resume my car audio dream I pull the alt out and I begin examining it and I notice there is a slight wobble to the shaft of the alt. I know things will need to be replace I contact DC Engineering and they totally take care of me and say just send it to us we will take care of you….. I’m floored they are being so cool about everything no hassle no nothing just hey yea send it to us and well hook you up man. I am literally going to buy another one to sit on a shelf. And wait for this one to wear out and I will swap it out immediately… Don’t bother looking around for High performance alternators these are the guys for you. They stand behind their product with a big smile because they know they have you back!

I inquired about an alternator for my vehicle and the representative gave me lots on detailed options for my situation. Great customer service.

Had alternator in my 2006 5.9 Cummins go bad (2nd in 2 years) so after a long search online I came across this company and decided that even though their 250 amp alternators are extremely expensive I’ve read nothing but good reviews on them so I purchased it...installed it on 9/18/20 and so far so good....hopefully this will be the end to my alternator failures

Really bad customer service, think twice before submit an order with those guys.

Received my alternator and it worked great. The techs there are very knowledgable and explain everything very thoroughly. Very happy!

Nice staff, they worked with me to make sure I got the correct product for my needs.

Worse company ever! The so called customer support, Anthony is not helpful at all. Whatever you do folks dont talk to him on the phone ask for another sales rep. He does not care and always seems like when he picks up the phone youre an inconvenience to him. They dont know what customer service is. Had to send my alternator in 3 times already. The last time i sent it in was back in Dec. of 2016 and still have not received it yet and its June 2017. The owner should get his head straighten out and fire some people in his company. I will never ever in my life recommend or buy another product from this company again. I spent almost $700 for an alternator that was half ass to begin with.

Guys there are really cool and knowledgeable. I recommend them to any looking for a great alternator.

Have bought two alternator from them have had one repaired and have one converted to use in a different vehicle. They know there stuff and are more then willing to help you.
