I would give negative starts if I could. I now have to hire a lawyer and will be sewing them. They did a head gasket job on my truck and they was supposed to stud it. They didn’t stud it and left a bunch of stuff loose on my truck. Had the truck back for 30 minutes and a coolant hose blew off of it. Now 13 months later my head gasket is leaking again building up pressure. This truck has never been over heated or anything. It started leaking coolant. He calls me after guaranteeing. Me it wasn’t the head gasket because they don’t do work like that and now it’s leaking and he is like well it’s out of warranty. I remember him telling me I had a 2 year warranty when I left. I think it’s sad the job I paid them over $7000 for only lasted 13 months. This is absolutely bs . Don’t use these people they will rip you off.

I can't say enough good things about this shop. As a Canadian truck driver, whose truck decide to throw a bearing in the rear end at 2 pm on a Friday, these guys got me in, diagnosed the problem and had the part ordered with 2 hours of my arrival. The owner, Merritt, and his son Steve were great to me. They drove me to a hotel Friday night and picked me up Monday morning. As well as drove to Indiana to get the new rear end for no extra charge. And then there's Tyler ( Steves son) who did all the mechanical work. This young man stayed late Monday to make sure I didn't have any more down time to get the job done. This is a great family owned business, and they know their stuff. Highly recommended if you're in the Dayton/Cincinnati Ohio area and need service. And oh....I forgot to mention, they build diesel dragsters too. Google 3000hp Climate Change. P.S. don't be startled by the big pitbull in the office. Blues a big baby.

Purchased an 05 chevy duramax dually from Steve Royalty. Three weeks later the transfer case went out in it. On the way to purchasing a refurb transfer case I stopped at Warren CO Diesel to see if Steve wanted to look at it as he had sold me the truck. He said he would and took the transfer case. Called me two weeks later and told me it would be $527 in parts and labor and that nothing was wrong with the transfer case. Immediately took the transfer case (after paying $450 to get it back) up to an expert in Jamestown (Nate Johnson) and had him actually take it apart. In taking it apart we had found that: The seals in fact had no been replaced. Most of the parts inside had not been touched or hacked together. This transfer case was opened then immediately shut. Steve will take you out of your money and have a smile on his face while he does it. Do not go here. Do not waste money.
