Peak Diesel MA LLC

Amazing people. They do reliable and very professional work. Highly recommend!

I picked up a new to me 2005 Ford Excursion 6.0L PSD over the summer, and once the cold weather came it was apparent that there was an issue since we had no heat in the cab. John and Dan quickly diagnosed the issue and offered great suggestions on other items to check/replace while the body was off the frame for repairs. Given my budget and the extensive repair needed to restore the heat, I was unable to go with all their suggestions at the time. Needless to say I am headed back there for more repairs that they strongly suggested I make, but finances wouldn’t allow. And don’t get me wrong, these guys prices are extremely fair, I would say if you are in the need of diesel repairs in the Palmer area, this should be your go-to repair shop!

Replaced my fuel pump along with other things in a quick time, reasonably priced and communicated well

I have a 7.3 powerstroke that I brought to several “diesel mechanics” no one could figure out the problem…just continued to throw parts at it and never fix the problem. I called Peak Diesel after hearing a few great reviews and I’m glad I did! I was in contact with Dan to schedule my truck to be looked at and describe the issues I was having. His customer service skills were A+. Previous mechanics would ghost me but Dan always returned calls and kept me in the loop with what he was finding. Peak Diesel diagnosed and fixed my problem in the original time frame that Dan told me. Reasonably priced and these guys do what they say they are going to do. I won’t be bringing my truck anywhere else, thanks again guys! My truck is running better than ever!

I've had a few diesel shops work on my 6.0 before going here and every single time it was a headache and left me disappointed with humanity. These guys have been fantastic though. Diagnosis has been on point every time and the fixes were solid. Quality work. They're genuinely nice guys and honest techs. They're an hour from me and but won't go anywhere else for diesel work.
