Seems to be a great price on a genuine GM alternator
On first blush, this appears to be an excellent price on a genuine GM brand new alternator. It arrived in a mostly plain brown cardboard box, well packaged with a high density foam surrounding it. The only real making on the box, besides the shipping label, was a holographic FM part number sticker. The best I can tell, it's a legit sticker and this is a legit part. Is it's fake, they did a great job faking it... Alternator seems well built, had no markings indicating it had ever been previously installed, and fit our 2014 Silverado perfectly. It's running smoothly, is quiet, and best of all it's producing power and not smoke like the old one! Only time will tell durability, but so far, I'm super happy with the product and the price. A very good value.

2015 chevy duramax 150amp alternator
2015 Chevy silverado 2500hd duramax with dual 150amp alternators. This was a direct replacement for either. Dropped right in and functions exactly as it should.

AC Delco replacement alternator works great.
The fit of this alternator was spot on. I swapped it in with very little effort and had all connections back in place including a new drive belt and the air intake on my 2014 Sierra in under 30 minutes. After starting the vehicle and testing the units out put, I was very pleased. It's working well and has solved my truck's electrical issues. Time will tell about the units longevity, but right now, it fits, it works well and for OEM the price was way better than my local parts suppliers. Highly recommend.

Good part.
This alternator worked great. Exact replacement. Casting was a little rough on the mounts so I had to file it for about 2 minutes, but overall good part.

Good GM Open Pkg Alternator
Priced great open package discounted genuine GM part. Said in very good condition but looked perfect. New one went in easy but removal of old took some patience. 2015 Silverado 1500 5.3L LT with 130K miles overcharging symptom. Fixed issue works great.
