I’ve brought three different vehicles to Top Notch for differential builds, and they nail it every single time. It’s hard to find a shop you can trust with drivetrain work, but these guys are true specialists. The builds are solid, quiet, and handle exactly how they should. If you want it done right the first time, this is the place to go. Highly recommended!"

Want to thank Juan and his team for the amazing turn around time and customer service through my regear of my 2021 Ram 1500. They finished it up in one day and kept in contact with my throughout the day to ensure me my truck was completed. His great prices beat competitors and his crew knows what they are doing, definitely recommend TopNotch Differentials to all my friends and others asking for regear or rebuilds!

I had my rear differential done on my truck here and couldn’t be happier with the experience. They were extremely helpful, very knowledgeable, and a pleasure to work with. I shopped around beforehand and I’m really glad I chose them. Great service and quality work — highly recommend.

Juan and Rigo, the owner, are very knowledgeable on their work. I am fully satisfied and very happy the differential job they have done on my 2002 4Runner. The noise is gone and the car is running just like a new car. I will recommend this shop to anyone that have issues with their differential. They are Top Notch and the price is so low and I couldn’t believe it. Try this shop and you will never regret it.

After searching for the right place to have my differential rebuilt on my 99 Ford F-150. I decided to take a chance on Top Notch Differentials. I called them and talk to them about the rebuild and got a quote. I filled out their online form and paid a small deposit. On the day I scheduled the truck to be there. I drove down to their business which is 83 miles away from my house. I thought this was going to be an all-day affair of waiting. And to my astonishment, they had my truck done within an hour! I was shocked I could not believe it. The ride home was 10 times better than it was driving down. They're very quick and efficient and have very friendly service! I would definitely recommend this place to anybody that needs a rear differential rebuild. I know not all cases are going to be like mine. But it was definitely worth the 83 mile drive. It explains why they're called Top Notch! Thanks again to the crew at Top Notch Differentials.

Was looking for quality and good customer service to build my 35 spline 3rd member and top notch was the way to go. Juan helped me with a quote first and any questions I had, gave me a price and helped me save some trouble with some bolts I was missing but luckily he had them in stock. Would definitely recommend and can’t wait to use them again on my next build!

I brought my Toyota Pickup to Top Notch because the differential was making a whining noise. Juan handled the repairs and had everything done within a few days. He was extremely friendly and professional throughout the process. The team at Top Notch does high-quality work, and their customer service is excellent. I highly recommend them!

Great communication from Juan and fast replies with any questions. The turn around time was really quick as well I got both of my gears regeared. Juan ended up texting me when they did the front that my hubs were seized and shot so if I wanted to change them they can do it before they put everything back and didn’t charge me labor. Over all satisfied with the new gears and the customer service.

Same day service is the best to get. After changing the differential, my truck felt like a new truck. It was a clean job and hasn’t had any problems. If you would like same day service plus high quality work. Goto top notch as they will hook you up with your needs.

Juan and Rigo took the time to explain the work being done and made sure everything was handled correctly and efficiently. The quality of workmanship is outstanding, and it’s clear Juan and Rigo take pride in what they do.

Great experience from start to finish.I brought my chevy suburban in for diff repair .I was referred here by a few people and they absolutely lived up to the hype. Best price I was quoted anywhere, same-day turnaround, and no surprises. It’s hard to find shops that are this efficient and straightforward. I’ll be recommending them to anyone who needs differential work done.
