An amazing shop was able to help me with my needs and gave me all the quotes I asked for right away! I have a LMM duramax they were able to help me with my burnt ground and new alternator. Also when I got my truck back and had another wire issue they got me in and out same day. They are very communicative with any questions I had and very understand with my issues I had with my truck. Will recommend them to anyone that has a diesel or any vehicle they need work on! Also there waiting room is very clean and has displays of upgrades you can do to your truck or other vehicles.

These guys are smart kind and go that extra mile to make sure that you have a great experience.
I’ve Been in trucking for years and these guys are amazing with both small and big trucks. I had to have a belt put on and the Canadian guy was very eager to help. He knocked it out super fast!!!!

ED and his team are great and know there stuff hands down. They worked with me when had issues with the a warranty company and decided to pay for it out of pocket. Highly recommended for all services.

Great customer service!! They took the time to answer all our questions. We were shown custom projects and personal vehicles that had services that we were interested in having done. Work was completed in a timely manner and we couldn't be happier. Big Thanks to the crew of Superior Diesel.

These guys are solid!! My Duramax lost a high pressure line 30 miles north of Vegas on my way to CO. After calling countless shops and roadside repair mechanics, I finally called Superior. Ed got me in on a Friday (same day) after I spent the night in my driver seat at a truck stop. They found the line that I needed and had me back on the road that evening. I can't thank them enough. It wasn't the hardest job, but the fact that they understood my situation I got my back on the road was awesome. Great dudes!
Thank you guys! The photo is from the following day on top of Vail pass elevation 10,666 ft.
