What others said about us

I took a transfer case out of a 66 Chevy down to Nate. He was super busy, but still managed to get it done on the date he promised. When I installed the case, it was found that the spring they installed was not the right one. I called Nate and he apologized for the mistake and said to bring it back down and he would make it right. They are a family owned business with excellent work and business ethics, otherwise they would’ve told me some BS story that it needed a bunch more work. I went to them because they came highly recommended, and I stand behind my decision to use them and will be using them again in the future.

Nate and his staff have always been very professional and informative. They make sure you know what they are doing and why they are doing it. I love the care advice to make sure your differential goes out of their shop and stays happy! Been using him for my shops for 6 years!

Scott Coleman

We have had the same car down to Nate a few times trying to fix a terrible vibration. He stuck with the project and finally helped us get it fixed. We’re super grateful and looking forward to cruising vibe free! Thanks again to everyone at AZ Diff for getting us back on the road!

Great people to work with. If you ever stop in here and look at their shop the one thing you should realize is that they are busy….really busy. If you are upfront with them and tell them that you have to have your stuff donr by a certain time I’m sure they are going to do their best. From my experience some shops are at the mercy of their suppliers. Parts don’t just appear and not everything is available the same day or overnight. This place is busy for a reason. Thanks for taking care of my 8.8 for my jeep. I’ll send as many people as I can to you guys!!
