  • Great project alternator
Was looking for a good low-cut-in 1 wire alternator for a small-diesel generator project. The Tuff Stuff alternator fit the bill perfectly. Now with a couple months' worth of running in, I can say I'm totally happy with my purchase!

  • USA made One Wire Alternator at a decent price.
Quality seems high, fit perfectly. It'll be some time before I run it. Will post an update when I do.

  • Quality and easy install
I needed a new alternator for my pickup as the old one stop working, after purchasing one from Autozone I exchanged theirs 3 times and finally got a refund. Saw a few YouTube videos and did some research I decided to purchase Tuff Stuff alternator. Upon receiving my order it was neatly packaged and the quality was as promised, hooked it up and the battery is now charging. I highly recommend and will be purchasing again for my other classic car projects. ... show more

  • Lasted less than 1K miles and fell apart.
I ordered this alternator because of the reviews and the stated specs. Specs were good, the quality was not. Everything looked in order when I installed it, and less than 1,000 miles later the bearing went bad and was making a horrible noise. When I removed the alternator, I found out that qty 3 of the long bolts holding the 2 halves of the alternator together were missing, and the last one was barely holding on. This has made me think about buying other brands. I don't recommend. ... show more

  • It was delivered ahead of expected time frame
I like the looks of the alternator and appears to be a quality product, unlike many of the cheap no-name alternators you can buy. There were no problems re-clocking from 12:00 to 3:00 for two plug connection. It is working as expected.
