AZ Differential Specialists

I brought my van to them to have the rear end rebuilt with all new bearings and seals. They got my van done in a day and also found out that the carrier was bad. They had another one and replaced it at no additional charge. They did awesome work at a great price! Will definitely recommend AZ Differential Specialist for all rear end work.

These guys do fantastic work. I could not be happier with their install of Nitro 5.29s on my Tacoma, the truck drives great and the gears are absolutely silent. I wouldn’t hesitate to recommend this shop to anybody else!

Called them earlier in the week to see about and inspection (had fluid coming from the differential housing) and said to come on down. Went down and one of the techs raised the car to have a look and found the issue and was able to fix in a few minutes. Thank you for your help and service, will most certainly recommend AZ Differential to anyone needing this type of repair.

I own a 2011 V6 Mustang optioned with the Performance Package, the differential has been an issue for quite awhile. Rebuilt by a high priced shop twice! A friend recommended AZ differential. I’m thankful and grateful for them. I highly recommend them.

Great people. Always get the best service from David and Henry. Shop may not look newer, but they know their stuff and can repair or modify any rearend. You won't be disappointed.

I tried installing 3.73 gears in my mustang myself and it wasn’t as easy as I thought it would be. My gears ended up
whining from bad wear pattern. David and everyone at az differential specialist got me right. No more whining, in-fact i think the rear end feels even better than what it was from the factory. 10/10 would recommend!

Best differential shop around Arizona hands down they located an axel that was discontinued anywhere in the U. S.

Great customer service same day service meaning they get the job done in one day better then great

I took these guys a set of premium Yukon gear set. When I picked up my rear end. It was not the gears that I took them very dishonest very dishonest. The premium Yukon gears have a black coating on the edge of the ring gear all the way around. Definitely would not recommend them. I don't know what type of business that does not want a reputation and not a dishonest one

I took my car here because my rear-end was making noise. The work was done and fast. Noise was fixed.
But when it came to ask question they didn't know nothing and had nothing to say. But after I paid they wanted to tell me the Rear-end was bent. The mechanic that did the work supportable went on a test drive. I waited over 30 mins and he never showed up.
Poor customer service.
* Reply to owners response ; I have my receipt with your address. I have no reason to lie And I have the the right shop.

They took me without any appointment. I went with a drive with Jose. He came back and crawled under the car and diagnosed it as a shock absorber problem. It’s a very honest company that cares about its customers. They only do differentials. They are like the surgeons who only do heart by pass surgery and transplants. Your car is in good hands with them.

Awesome business. Excellent communication, clear and concise estimate with realistic expectations. The work was done correctly the 1st time and ahead of schedule. Sure I could have done it my self cheaper but it would have been the 2nd time in 40 years. If I messed it it would cost alot more. Setting up a diff is a skill, leave it to the pros

Fast and reasonably priced, great customer service. Jose serviced the Diff and changed the leaky pinion seal in about 15 minute's. I was outta there. TY

Az Differential did and outstanding job on my 1964 Impala SS rear differential.
Shop staff broke down rear differential, cut and narrowed differential to fit my vehicle better with rear skirts. During disassembly I was able to powder coat housing, return to shop and staff reassembled differential in a timely manner.
Work completed was outstanding and highly recommend Az Differential.

The guys at AZ Differential Specialists are top notch. This is the 3rd Jeep I have had them do gears on. I wont go anywhere else. They are always on time on budget and my parts come back cleaner than I dropped them off. Thanks again for the great work.

Awesome shop. Highly recommend. They go above and beyond. Did my gears as quoted and even quicker than estimated. Wouldn't go anywhere else

Highly recommend this place for any differential needs! I went from 3.55 gears to 4.11’s and the truck runs and pulls great! Great guys with great price and fast turn around time!

Had an axle leak that another shop screwed up and didn’t stop the leak. These guys took care of me same day. Will definitely come back for any service they offer.

This place is great people and great work. Needed new race 3rd member to get me back on the track. Done. Thanks David and all.
