Peak Diesel MA LLC 144 Palmer Road, Monson, MA 01057

"From out of state. My truck went into limp mode. Called John up and he made time for me and fixed the problem and got me right back on my way."

"I was having some problems with truck completing a regen. I dropped it off at Peak Diesel and they figured it out fast and were fair on the price. I highly recommend them."

"Incredibly knowledgeable and friendly. Have a 2016 Duramax and they knew about all variations and options for dealing with some fuel system issues. These guys are always very friendly by phone and giving advice, was happy to get the opportunity to hire them to do some work. Both gentlemen, both extremely knowledgeable and transparent. Enjoyed working with them, and hopefully many miles before I need to go back! Thanks for the help."

"My first time here and having issues with the turbo on my 2007 Dodge ram diesel 6.7. Met with Dan to figure out what we need to do. He was very helpful and I decided to have him change the turbo. Work will be done this week. Looking forward to having my truck running like it should again."

"I have an older diesel truck that I was hunting for someone to do some serious work to. These folks came highly recommended from a friend who owns his own repair garage. One of his regulars brings their diesel there for diesel specific work, and it's always on time and under budget. What more could you ask? After interviewing a few places, these guys won hands down. Dan was extremely knowledgeable and I felt instantly that this was the right place. I dropped the truck off and it was back before I needed it, running better than it's run in a decade... and it was under the price I expected! Highly recommend - Give them a call!"
