Valley Differentials

If you have any need what so ever for differential repair, service, inspections, you name it… Myles at Valley Differential is absolutely your man for the job! I cannot stress enough just how great of a guy he is and his work is as solid as it comes. Not to mention he backs up all of his work 100% with the included warranty.
He did a full build in my 1972 Pontiac GTO/​Lemans which included all bearings, seals, Eaton posi, and 3:55 gears. It was an 8.25 BOP rear and required a different yoke that would he would have had to order and would have delayed things, but Myles being the great guy he is, he was able to make a few calls around to friends in the industry and found me a yoke to be compatible with my requested gear setup. To top it all off… he didn’t charge me one penny over the original quote, and even got it done before the date promised. Once done he took the time to chat about proper additive (FORD friction modifier), proper break-​in, and any other questions I had throughout the whole thing. The Lemans is still going strong and that was over 6 years ago!
I have made it a point to tell anyone and everyone I talk to that I know needs some type of differential related work, or plans on getting some work in the future about Myles at Valley Differentials, and when I saw his business listed here because I needed his number to call about some work on my truck, I wanted to make sure to take the time to leave him a review here as well because I cannot say enough good things about Myles, his business, and the way he conducts himself and his business in general.
If you read nothing else just know this… A++++ work, great guy, completely fair prices, solid quality work, and the last mechanic you will need as far as anything differential related! Don’t even hesitate to call and talk to Myles and I know he will take great care of you and your vehicle. Keep up the great work Myles, we need more solid guys like you in the industry!

I was recommended by my mechanic to Valley Differentials for changing my rear end ratio. Myles ordered OEM gear and pinion. 20k miles later everything is quiet and no leaks. Could not be more satisfied. Honest, knowleagable, and fairly priced.

A++++++ Highly recommend
I needed to change my gear ratios for my 2010 GMC Sierra to tow a trailer that was a little heavy for my truck. Valley’s quote was lower than all the other guys I had contacted, so I elected to have Valley do the work. Little did I know that GMC had a specialty transfer case required to complete the gearing change. Rather than put spacers in and complete the work on the cheap, Miles special ordered the expensive part and completed the work quickly without even batting an eye. Even offering to cover the additional cost of the part. A real stand-​up guy and even better mechanic. I was blown away by the level work and attention to detail that Miles put into my truck. Would recommend Valley Differential to anyone and everyone.

Rear seals on my 04 Titan were leaking, They changed out the seals, and bearings and I’m super happy with the service and the price, Thank you Valley Diff!!!

Edit: Bumped to 4 stars. Little time puts things in to perspective. Myles is a good guy who did good honest work.
I don’t know who is really to blame for all this, but I’m gonna give them the benifit of the doubt. The price was decent and they are pretty friendly. It took way longer to get the part than expected, and they told me it was Maita Subaru to blame for many reasons (read my review of them to see it). Based on the horror stories there I don’t see being lied to by Valley Differentials. The delay kept mkney out of his oocket and me out if a car. I would have to call them for updates since he always seemed to forget calling me back the next day, but it wasn’t horrible. Partly could have been me wanting a daily update for such a small job.
