Rearend Specialties

Rearend Specialties is a great shop run by honest and kind people. I had my GM 8.2 10 bolt rebuilt about two years back. They were very communicative, met their deadlines, and informed me when they found issues bent axle shafts. I sourced parts myself, and the team was happy to accommodate my requests. The axle has performed nearly 20,000 miles without issue, but I did notice a bit of a whine developing on deceleration recently. I brought it back in for a check-up, and Mike was able to get it lifted up, re-torque my pinion nut, and ensure the proper pre-load while I waited. He did a quick inspection to ensure the axle was still in good shape, and sent me on my way without a bill. There's nothing better than a communicative shop that stands by their work, and I thanks the guys at RES for taking care of me!Service: Steering & suspension repair

Rearend Specialties has regeared and installed lockers in 6 axles for me over the past 8 or so years. Many daily driven and hard offroad miles later and zero issues. One of the few shops left in the bay area that can properly set preload and backlash in differential gears.

Adam and Sarah did a great job getting my Toyota rear end rebuilt faster than I expected. Now I can enjoy my 94 toyota once again. They even offered to upgrade to Eaton posi traction. Thank you.

I was concerned about gear noise on my Tacoma. Sara responded quickly on email, and despite being fully booked for weeks Adam was happy to spend 20min test driving and looking under my truck and only a few days after I emailed. In the end it seems like the gears are OK. I offered to pay but they declined. Great experience.

Came here to get a e36 LSD rebuilt, they swapped the ring and pinion as well too boot. They also allowed me to drop the unit off and buy my own parts which in turn saved me a lot of money. They were also able to give me an extremely reasonable no surprises involved quote over the phone which no rear end builder in the south bay would. Everyone else said bring it in and well take it apart then quote you.

I was very satisfied with Rearend Specialties . I took my rearend to them thinking it was going to be extremely expensive. That was far from the truth. Not only did they have reasonable pricing, they are honest. My differential ended up to not be broken. And they told me it may not be broke before they opened it up . I don’t know much about rearends so they could have told me anything and they didn’t.Very refreshing. I ended up doing an upgrading to POSI and they did a great job! I’m a very happy customer.

Brought in my complete diff for a ring and pinion gear change as well as putting in stronger axels and a true-track limited slip. 4 days later it's a done deal. My baby got back now! C; Mike was straightforward with the estimate and stuck to it. They saved all my old parts and even hot tanked the diff per my request. The work comes with a 1 year warranty. Ended up costing 1/2 the price of a new one. All they do are rear ends and they stay busy. That should tell you something C:
