Had another great experience with Unitrax, clean work, on time, good pricing.

I brought them four differentials over the last two years and they always knock it out of the park. Timing and price are always good too

Long-time customer of Unitrax since 2013. Got a few differential setups for different Miatas and 86/FRS/BRZs over the years; a couple of them went to set road race circuit lap records and win championships. Always quick turnaround time for bench jobs and customer support is top-notch.

Eddie's a good guy; he called me about missing a few seals for my last differential rebuild and quickly got some to get the job done. And his communication is precise, to the point, and polite. Thank you good sir.

Give this place a 5 star review, especially Eddie. He went above and beyond to provide great customer service. I went to another local shop were they quoted me 3-4 week lead time. I followed up with them a week later for they never called me back for pricing where they informed me they haven’t even checked on it. I took my business here and it was the best decision I could have made. Eddie got me a new axle, shortened it and had it ready for me in 2 days and 35% cheaper than the other shop. Thanks again Eddie. One happy customer here.

These guys deserve 5 stars. I was traveling through town on my way back to the Bay Area when I encountered a mattress that wrapped in the worst way around one of my driveshafts on my 1999 Ford F-350.. I spent a lot of time in the emergency lane removing it. When I got back on the road I realized I had damage. I showed up at opening time without an appointment. Not only were they able to fit me in, they had the parts and did the work right then while I waited. I was quoted only what needed to be done as the minimum, but also recommended what might be best to do. Clean shop and all the right tools. In addition to pressing on the center bearing they balanced one shaft that needed it and also replaced u-joints. All parts were stock! I have to admit, when I left there I knew I was not going to have any issues on the last leg of my trip, but never on the part of my truck they worked on. Get your work done here!

Good/ Honest Company, brought my 2004 Sportsmobile in for an axle leak repair, in the rear-passenger portion of the axle, fixed it promptly. Second time I have used this company and they always do what they say. Reasonable price and appreciate repair shops, that handle this special type of service that few people can do. Also, I had many valuables in my car, nothing gets touched or tinkered with. Great Job Unitrax
