Professional and knowledgeable shop. Cohl and his team fixed my truck and did great work. My truck is back on the road and runs better than ever thanks to Allegiant Diesel. I would send anyone I know to this shop.

Couldn t ask for better service, dropped my truck off on a Saturday night with a crank no start it was diagnosed and fixed within a week. I was kept up to date every other day unlike other shops where you have to call and ask what s going on. I highly recommend Allegiant diesel to anyone who is looking for fast and great work. Will definitely be recommending this to all my diesel friends

Colton and his crew installed my new S&S DCR fuel pump and made a few other minor repairs I requested. The work was completed on time and at the price quoted. I will definitely use Allegiant Diesel again as they treated me great and were very easy to work with.

Seems like it s becoming a challenge to find shops that still believe in quality work and service, thankfully we found cohl. Told him we had a truck we wanted to make reliable and be able to tow efficiently. He went over the whole thing gave us the run down and kept us up to date on his progress and then explained and showed us everything that was done when we picked it up. We really appreciate it and will definitely be back!

I ve never owned a diesel before until recently and I reached out to the shop in hopes they could look at the truck and tell me anything that would need fixed or replaced. In a very timely manner, the owner replied to me and did a full inspection of my truck and gave a very detailed report. I highly recommend taking your vehicles to them. They are respectful and hard working and will make sure they get you what you need.

Cohl and his team are incredibly professional and they do fantastic work. I brought my truck in for a new transmission and they had it done in under 2 weeks. Less than half the time I was quoted from another shop. I highly recommend Allegiant!!

They got me in when I was in a pinch. Very knowledgeable and I was impressed with the short amount of time it took to diagnose the problem. Super nice guys, treated my wife with respect when she picked up the truck. I will definitely go here again.

Brought my truck in, in a hurry and these guys did their best with getting me in even being a difficult long job and gave me a product quickly that im extremely happy with. I would recommend this group of guys to anyone!

Would give zero stars if I could, the mechanic is very skilled, and has plenty of knowledge when it comes to Diesel s. The owner on the other hand is a young disrespectful kid, he will laugh in your face when you ask if your vehicles is done and does not care if your vehicle is still showing the same codes you took it in for. All in all I would try to find a different shop to work on your trucks, the owner is a joke to deal with.
