I took my 99 F350 in for leaky injector cups. They gave me a start date and a finish date. Even with a fair amount of other problems. They got it done when they said. They went the extra mile of fixing a bad fuel pump to get the injector pressure up to spec. My truck runs nearly like new, even with 400,000 plus miles. Forget the dealer, this is the place!

I have taken my 2004 Superduty to several shops in the valley looking for quality service. Not many diesel shops around in the east valley. Regular shops sometimes cringe when you tell them you drive a diesel!! I have found it with Monster Diesel! Just recently I took my truck in for the 110, 000+ mile service and hard start concern. I was contacted prior to any repairs and so I knew what was going to be done. No surprises. When I went to pick up my truck I was also informed of other potential concerns that I appreciated being informed about. Quality service. Thank you.

I think it is important to share this with other Duramax owners with truck years 2011-2016. You may or may not be aware of an issue with the duramax that a injector pump failure causes a total failure of the truck, and has a repair bill in excess of $13,000. My situation is that my truck is a very important part of my lifestyle, as we fulltime RV, and travel to some remote places. I say all this because Mike was the only tech that even mentioned that the replacement of the injector pump is necessary to ensure reliability. Having known this issue Mike was the only shop owner that I talked to that knew this and recommended this replacement. Thanks Mike for the great job and the sound advice.

I am so happy with the service!

I have a 2000 F250 7.3 pulling a 10K 5th wheel. It was a little weak and I called Mike who made recommendations for an upgrade. I had my own ideas but Mike had done hundreds of these upgrades and showed me my error in thinking. I am so happy with his expertise, his customer relation skills, his technician who did the work. I had the truck chipped, up pipes, turbo, and and oil link all done in one day. Truck performs beyond my expectations. Thanks Mike. - Bryon G. (5 star review on Yelp)

Monster Diesel know what they are doing!

Mike at Monster Diesel was very helpful and did a great job finding the low power issue on my 6.4l Ford, complete vehicle inspection, and oil change. We were on vacation, from out of town, and took a chance by choosing his business, based on previous reviews of other customers. Simply stated, Monster Diesel knows what they are doing and how to treat customers professionally, efficiently, and with honesty. I would recommend you give them an opportunity to earn your business and respect too! Well done, Thanks. - Keith I. (5 star review on Google)
