It was a very good experience

This is my first experience with Tucson Alternator. I am a big fan of rebuilding factory parts when available and staying clear of aftermarket trash. I arrived to their place before opening but was invited in (because of my classic Bronco or just how they roll is not known 😆 ).

It was a very good experience

I highly recommend this company. They gave me fast shipping which I really needed since I was going on vacation. My 400 amp alternator was a direct fit and replacement. It works perfectly as expected and came in brand new condition.. it came with the read outs of all the test they performed on my alt before shipping. I highly recommend Tucson Alternator for your next High Output alternator. I will buy again in the near future. Thank you 🙏🏾.

It was a very good experience

These guys are very knowledgeable and reasonable to work with. At the very minimum it is worth it to take your alternator in to get tested, because they can tell you exactly what is wrong with it and how to get it fixed. They offered me a reasonable price for the repair and had it done within 30 minutes. This is after AutoZone told me my alternator was "bad."

It was a very good experience

I needed a new alternator for a Volvo Penta 5.7 application. The stock replacement (75 amps) is around $300. I found Tucson Alternator while searching and called them up. After finding out I could get a 170 amp direct-fit alternator for not much more, I immediately placed an order online.

It was a very good experience

These guys are awesome! They took the time to explain everything to me in simple and clear terms, and made sure I had exactly what I needed the FIRST time. I couldn't recommend Scott and the rest of the team enough.
