“Great customer service and fair prices. Called one morning with problems with my truck. Got to the shop and instead of being fed a whole list of stuff that I didn’t need Clete took a sensor out of my truck cleaned it and reset sensor and I was back on the road. Fast forward a couple days later I had another problem going on with my truck. Alternator was failing after I just replaced it a year before. Clete took alternator out for me and installed the replacement for me. Honest trust worthy diesel mechanics are hard to find. Talked with them about getting some other stuff done. Will be giving them my business for here on out."

"We are a traveling electrical company and we have dealt with all kinds of shops across the country from Ga to Ca.... Simmons Diesel Performance is by far the best experience we have had hands down! The mechanic is very straight forward and truly knows his stuff from radical performance to general service. They even have a state of the art in-house transmission department in their shop which makes turnaround times very impressive. We have all of our trucks towed to his shop regardless what state they break down in. At one point he even went to another state to pick up one of our broke down trucks! If you're looking for experienced service at competitive prices this is your place.
Thanks for all of your help Cleat!!!"

"So thankful for these guys. We had truck problems during a trip through Barnesville and we stopped here. Within just a couple of minutes the guy knew what the problem was. He got us going in less than 15 mins. My family appreciates this more than we can express. 20 out of 10 would recommend."
