This is another great American business with the proprietor at your service. I was welcomed warmly and treated fairly with every aspect of the repair to my vehicle. I have F450 Turbo diesel with a 7.3 International engine. I couldn’t be happier with my experience I would recommend them to anyone. Chad Hurley.

If you’re looking for a diesel shop that will get your rig running for a fair price - this is the place. No constant upselling or 379-point inspection to find more repairs to perform. I’ve been here 2x and am happy with my service both times.

Deranged Diesel Repair, the shop that took care of our battery issue, was awesome! We were extremely pleased Steve took care of our needs immediately and professionally. We were in and out in an hour! When we were traveling finding this shop was a blessing!

I decided to use these guys to rebuild my 6.0 Powerstroke. It was a big job and an expensive one. I had a huge list of things to do with a full engine rebuild. They were fair on the price, but when it came down to some options, Steve recommended a couple and steered me away from a couple that were not necessary. He did not act like a typical mechanic and up sell just to make more money. Ben did the work very well, I checked up on him a couple times. It was done on time and ran great. A few months later I used them again to replace my cat converter. They did an awesome job on that too. Now I’m not the type of person to leave a review but about 8 months after the motor rebuild I lost all of my transmission fluid while driving about 50mph. I looked and saw it was coming from my transmission cooler area and figured I blew it. I took it back to them to put a new trans cooler in. Knowing Deranged doesn’t really inspect or rebuild transmissions I told Kimberly I was going to have it towed to my transmission shop after they did the work so I could have my transmission inspected to rule out any damage. She said okay and wrote up the work order. Steve called me later that day and told me he could see where a clamp was not installed properly by them and he would cover any damage caused as well as whatever my transmission shop charges me for the inspection and refilling it. This blew me away! I was so impressed by his honesty and willingness to make it right. Steve even had Ben power wash the entire undercarriage with a hotsie after I got it back from the transmission shop. These guys are GREAT! I would fully recommend using them.

Steve is 100% honest. I thought I needed a King Pin replacement on my Intl LT 625. I ordered the parts Steve asked me to get. We had a previous diagnosis so we thought we knew what we needed. First, he scheduled us in for the repair immediately. Upon the start of the job he called me immediately to say the following - "I cannot ethically change the king pins there is nothing wrong with the current setup." He then stated the only things it could be and we decided to make the change to the shocks. Not only was that job done quickly and fairly, he also repaired several air leaks. Steve is an outstanding human being ethical and honest. You'll want to hug him - BUT he is not a huge fan of hugs from strangers. Thanks Steve

Had an unexpected issue with my semi and called around the valley looking for a shop to get it fixed immediately. Of course every shop I called was out at least 2 to 3 days. I found Deranged Diesel online and gave them a call. They were able to get on my truck right away and get the parts ordered and installed in just a few days. They did a great job and were reasonably priced. They are very thorough and would recommend them to anyone. No issues with the repairs and truck is operating perfectly.

The mechanic shop we were going to changed directions and we were directed to Deranged Diesel Repair. We called, got an appointment fast, easy to find, and most importantly our previous shop trusted them. Arrived at the shop for service and were greeted by Molly, can’t say enough about her, very professional, easy to talk with, customer service and then some! The owner Steve answered our questions and didn’t make you feel like you were wasting his time. Work was completed and then the mechanic listed items that needed to be addressed and talked me through them. No pressure. Thank you Kasey! If you are looking for a shop that is trust worthy and can do complete service on your diesel then this is the place. At least that is the experience we received! Thank you again Molly and Steve for your service to our Country!
