I can’t say enough good things about Doug and his team at SW Diesel. The first time I used them it was for the Allison Transmission problem. They Did such a good job I didn’t hesitate to use in the following year when I was back down in St. George this time I had a vibration had a loss of power and they fixed it all. I left St. George went to California to California back up to the mountains of Arizona and it pulled everything beautifully. I highly recommend the team at SW Diesel.

Doug and Darren have been working on our semi trucks for the last 8 years. They have helped us on road side emergencies and with arrangements the get heavy haul towed several times. The nice young lady that answers the phone during business hours is very helpful. If you want a down home diesel shop experience give them a call. I do warn you that their could be a story or tall tale told when doing business with this too mechanics.

What a great group of people! I've been dealing with them for almost 3 years and they are always super friendly and honest in the way they do business. It's hard to find a business that still goes the extra mile and treats their customers with respect and appreciation. Highly recommend!

I had an extremely disappointing experience with Southwest Diesel Service. They charged me a ridiculous $1,100 to repair a mudflap hanger, a job that took no more than an hour to complete. This level of overcharging is completely unacceptable, and it’s clear they prioritize profit over honesty. If you’re looking for a fair and trustworthy repair shop, I strongly recommend going elsewhere. This place is nothing short of shady, and I would never trust them with anything. Complete liars! Avoid at all costs!
