Drove down from Ray, a three hour one way drive. They did the job, faster than anyone up north, way better quality, and cheaper rates. I'll always make the drive down there to save time and money for now on.

Had fuel issues on my 2001 Newmar Mountain Aire. I had the filters. Pulled into DAK. They checked the computer codes. We agreed to change both fuel filters. 1 hour later we were on the road again. Excellent service. Thank you.

If there was a way to give CJ at Dak Diesel 10 stars we would. Blew the head gasket in our motorhome in Bismarck ND no other shop was able to get to us for weeks. CJ squeezed us in right away and did a fantastic job for a fair price.

We have had many vehicles worked on throughout the years. I would not trust anyone else with our expensive pickups! Dak Diesel has proven to be the best in the business. Their countless years of knowledge and experience sets them apart. I trust sending my family down the road in anything from Dak Diesel.

We live in Stanley, ND and take all of our semi-trucks, pick up trucks and even our tow truck to CJ at Dak anytime we need engine work. We have done 3 in-frames on Semi-trucks and other major engine work there. Price is fair, invoices are clear, work is professional. If only he could clone himself to get more work done faster. DAK diesel is worth the drive, we refer all of our trucker friends. The icing on the cake is supporting a small business where the owner is a genuinely nice and honest guy. No wonder they are busy.

I called CJ about my 2012 Dodge Cummins. I told him I was not interested in all the fancy upgrades all I really was concerned with was fuel mileage and more power. He didn't try to sell me anything I didn't need he looked at exactly what my needs and wants were and gave me a very good package for a reasonable price.  He did the upgrade on my pick up in a matter of just hours. Upon receiving it back I had so much power I had to learn to redrive my pick up because it would break traction on dry asphalt. In addition to this I increased 6 miles per gallon on interstate driving. When I am on the interstate in a three-quarter ton diesel pick up doing 20 to 21 miles per gallon I am very happy , also in start and stop situations running back-and-forth to a small town I am averaging over 16 with that as well. I am very happy with the treatment I have received from DAK diesel I highly recommend doing business with them to anyone else

I had injector work last year. 2 injectors replaced. CJ did a great job for me, so when I needed motor work done last month, I called for an appointment.

No more motor issues shooting codes to the ECM. Running and breathing better now. I Do need to set another appointment to have the rack run (almost 150,000 miles) so it's time for it now. Shouldn't have any other issues after that.

I strongly recommend DAK Diesel for taking care of your diesel.

Thank you CJ



*****Update on recent visit!!! *****

What a change in the past few years! Congratulations on being so busy. I had a recent issue come up, needing some attention. CJ and his guys come thru for me again. These guys could have really raked me over the coals and charged me tons, but they don't. They don't up sell anything really. They suggest but thats it. I am really thankful I have these guys as service techs. Great integrity, awesome work (and fast, most of the time) and worth the cost.
