Outstanding customer service and workmanship, and the nicest guys in the biz. Very knowledgeable and not at all judgmental of anyone who is new to diesels. Highly recommend them for any work or service needed on your diesel rig. They absolutely wont do unnecessary work or try to talk you into buying parts you dont need. They are straight-shooters and a very honest, reliable and dependable outfit. And no, I have not been compensated in any way to write this, and have no personal connection to DK Diesel other than being a very satisfied customer!

I had my 6L Powerstroke fully updated. I got photo updates of the progress and was pleased with the frequent communication. The work was done right by a very capable crew. I then pulled a 15000 lb trailer 3000 miles without a single problem.

Wonderful customer service, so far the quality of the parts are identical to the BIG NAME AKA the blue guys parts..... THE ONLY thing Ive found disappointing is I bought the head gasket rebuild kit with the studs and coolant filter with TONS of O-rings and other accessories BUT NO INSTRUCTION or parts manuals. Had to call for torque spec for studs WHICH they emailed promptly.

These guys are awesome! I work in the deisel industry so I know how it works. Brian was always excited to put up with me. I had 25 overs put in my lb7 and they have great rates! They installed them and got a bad injector but still turned around and helped get me truck torn apart and put back together for the second time with a tune quickly! Painless experience even with hiccups and good attitudes. See you guys next time I need work done!

Very knowledgeable, excellent prices.Would recommend them to anyone.

Cant say enough about this place and the people that work there. I was hesitant at first because of all of the aftermarket tune ups they do I thought they might try and upsell me on parts but that was not the case. I have an old Ford 7.3 that Im just trying to run as long as I can and have it be reliable. I had another shop in the area tell me I needed all this work done that would have cost me over 2k to do. I took it to DK to get a second opinion. They fixed my truck and had me on my way for around $400.00. Plus it was only around $60ish to change my oil when everywhere else is around $150. Brian is very nice and helpful over the phone and their service has always been timely. Unfortunately work has moved me away from Bellingham and now Im back to trying to avoid having a mechanic bleed me dry. I miss having DK Diesel be my primary Diesel shop.

Very informative and helpful on vehicle needs.

These guys are awsome I needed to rebuild my transmission in my lly duramax and they went above and beyond the call of duty. These guys know there stuff and Ill never take my vehicles to any other shop again Thanks DK Deisle

Fast, they had all the parts in stock. Reasonably priced, work cost much less then estimated. Staff was helpful, and knowledge

These guys are excellent. They went above and beyond each time I needed service. Their pricing was competitive on the small and big stuff. I highly recommend DK to everyone because they impressed me so much with there service. They went above & beyond on multiple occasions for me, were patient, professional and efficient.

Had a fair bit of work done here, fuel system upgrades including injectors/ injector tubes, fass fuel system/sump, harmonic dampener, serpentine belt/fan clutch/water pump. Ran into small issue where Fass stopped working, Brian determined it was just a fuse and popped a new one in free of charge on the spot, no leaks or issues with work done. Very willing to discuss ideas and options with you and reasonable on pricing, would recommend. Cheers

Great service! You will always get the best advice for service for your vehicle or equipment. DJ, Todd, and Brian are the go-to people to ask. I wouldnt trust any other shop to work on my truck. Even when I do repairs, they are outstanding on helping out by giving advice.

When I took my Dodge truck in the first time I got a thorough diagnostic run-down so that I had a list of stuff that could or should be fixed. Some of the stuff was easy to fix, so I did it myself to save money. Other stuff, like fixing the air filter and cleaning my injectors I had them do right away. This allowed me to pick up about 2.5 to 3.0 miles per gallon driving in town. Just recently I had them do some work to the emissions system and exhaust. I picked up another 5 miles per gallon doing this work. I liked their no-pressure approach and focus on customer satisfaction. I would recommend this business as an alternative to taking your truck to the local dealer for service!

These guys have kept my 1999 Dodge ram on the road since I bought it 10 years ago. Due to their diligence on maintenance I have 400k HARD miles on my truck. They have always gone the extra mile to get the work completed on customer induced tight timelines etc. I now live 5 hours from this shop but it is still the only shop I let work on my truck. The fact that I incur extra costs and travel time to get to this shop should illustrate the quality of their work. This review does not constitute one trip, but rather 10 years of service.Just wish the owner would smile more.

These guys have worked on both of my trucks and did an amazing job.. bought many parts from them and if some issues came up theyll take care of you very quick.. also DJ did an efi live Dyno tune on my mega cab and it bumped me some serious power and I can tow without any issues on high egts even on the highest settings..these guys really know what theyre doing.. always recommend them to anyone and always will

Love working with Brian. He is very straight forward with the repairs and quotes.

Todd and Brian are awesome at giving good advice. They defiantly know there stuff. Answered all my questions and recently had it in there shop They do a awesome job. Would highly recommend DK Diesel for all your needs. Exellent work high end parts No junk on your truck! Cant say enough about these guys work!

Dk has been working on my 2005 dodge for the past couple of weeks. They have done diagnostic, suspension and injector upgrade for me. I am very pleased with the service done! Parts where very competitively priced and the injectors were actually much cheaper and higher quality then I could find on the Internet. Staff was experienced and was willing to work with my busy schedule. Will do business again!

Its a really nice shop they did some work on my truck, installed lift kit, those guys are professionals

Brad has been a big help and very knowledgeable. This is my first choice to keep my old truck on the road

These guys are great, really know their diesels! Got me in super quick and even took a CC over the phone so I could pick up my Ram 2500 after hours!! Definitely look them up if you have any diesel problems or are looking for some awesome mods.

I ordered a bunch of parts a few years ago and dealt with Todd. He made sure all my questions were answered and my order was correct.

If you have a sickly Ford 6.0 Liter DK Diesel has the doctors to make it better!These guys tell it straight, no bull and not trying to sell things that arent needed.Very pleased with the service and the speed theyve performed the jobs.From all the crew over here at Fountain Rental Thank you!

Very knowledgeable, professional and friendly. What else could you ask for. Trust them with my toys and they always over exceed my expectations! Thank you

Brian, Brad and the rest of the DK crew have been great to me and my son. Excellent service!

Have tried a couple shops and DK has the best pricing and service.

Purchased from them off their website. Great price with fast processing and shipping. Cant ask for more.

Always my GO TO. AND, always very satisfied with every aspect of the experience.

Great bunch of guys doing excellent work.
