Works for a 2006 6.0
I've been running this in my truck since January 2024 so it seems pretty durable. It's a great fit in my 2006 f250 6.0 powerstroke lariat. It's been working great ever since installing it. It doesn't have very high amperage, but it's better than the 110 that came stock. It's a great value for the money if you don't need a whole lot of power. It was very easy to install. Took me about 15 minutes.

2002 F350 7.3
As of day one it works perfectly. Charges 14.2 to 14.3 . The best one of the last four I have put on my 2002 7.3 power stroke. The clocking is a little off but it still worked. I didn’t use washers to space it up I used an aluminum carbide and die grinder and cut the bottom of the saddle .

2003 f250 6.0 diesel alternator
The product arrived in a timely manner with no issues and well packaged. However the only thing was that the plugs were on the right side instead of the left side, the good thing was that my wire harness had enough slack to actually reach and connect. That is why I’m giving it four instead of 5. It said it was for my truck but connections were on the opposite side. Products looks great brand new and it was a really easy install. I give it a two wrenches hard. Anyone can install just four bolts and one two cables to disconnect. Great value for the money and when I went to start the truck it started right up. Battery seems okay and the red cell light did not turn on. The reality is when I drive it to work to see if everything works fine. Good quality.

Works perfectly!
Bolted right on with no modification. 05 Excursion with 6.0L power stroke. Headlights do not fluctuate from dim to bright any more.

Contact seller for proper fitment
Works great on my truck and seems of very good quality on the workmanship. I do recommend contacting the seller to ensure proper fitment. Mine arrived with the clocking off by one set of holes. Opening the case to reclock voids the warranty which is understandable as not everyone can rechecked an alternator without damaging it and they are only protecting their interests. I had to go ahead and do mine because of time issues and couldn't wait for another. Over the years I have problems done a couple hundred of these on the rechecked so it was a non- issue for me. I did have several message exchanges with the company and they are more than happy to assist in anyway they can to make sure you get the right product. So I would not just take Amazon's AI program as gospel on fitment. Take a couple extra minutes and call or email them (they are very quick to respond to email) and they will make sure you get the right product

Pleasantly surprised, it's not garbage.
I've been running this alternator for a year now and it has been great, no issues (knock on wood). I was a bit trepadacious at first and didn't expect it to last long, but I have been pleasantly surprised. Thanks for putting out a good, affordable product.

Poor quality
I dislike when you buy Chinese stuff ( everything we purchase online) that the return window is only 30 days. I’m done. 40 days old then the item fails. Only support is troubleshooting. Ugh This doesn’t help at all, the alternator insulator where the battery cable connects fails then the battery cable end now makes contact to the alternator body. And burns the cable end. I’m now out of a new alternator and now replacing the battery cable end.

Damaged product twice - needed to replace in less than 4 months' time
Purchased this twice and twice it arrived damaged. The second time it didn't seem as bad, but after only 3 months of use, it the alternator quit completely. I would strong caution against buying this product. I'm now out the money for the original one I bought (this one), the cost of having it installed and now need to purchase another one and pay to have it installed less than 3.5 months later. Super disappointed.

Complete garbage
Do NOT buy this alternator for your 6.0 power stroke. This thing ran so hot and smells like burnt electronics also has a whining sound after first drive didn’t even last 20 miles!!
