Casey and his guys always do great work. Never disappoint. Affordable prices as well. I don't take my trucks to anyone else.

Twin peaks has been good to deal with so far. They have worked on a couple vehicles for me and the fixes have lasted and worked. I will continue to use them. They only work on trucks 1/2 ton and above, they do semis as well.

When Ford in Longmont tried to charge me $4000 to fix a death wobble issue on my ford 2015 I went with Casey to get a second opinion as he has helped me before with excellent service. Casey and the team diagnosed the issue and it turns out my drivers tire was very unaligned and just required a alignment and balance. That seems to have fixed the issue and I cannot be more grateful with everyone at Twin Peaks diesel For diagnosing the problem correctly when the professionals at Longmont Ford didn t even catch it and would ve charged me for something totally unrelated. Thank you all so much and appreciate it always

Our truck started smoking about 5 miles from this shop and we just made it there before it seized up. They took a look at it and quickly diagnosed it. They ordered the part and in about an hour and a half we were back in the road! It was amazing! These guys were top notch and really friendly.

I can t say enough good things about this place. Awesome people that are friendly and very very knowledgeable. They have worked on my Chevy Tahoe, ram 3500 Cummins, and my kw w900. They figured out the problems with each of my vehicles quickly and made the repairs in good time. I use my ram and kw for work and every time I have had problems they did everything they could to get me on the road ASAP. I will use them for everything because I know they are a good shop that will be around for a long time.

I would like to say that the owner is not your average mechanic shop owner! He is honest, accommodating, knowledgeable, and extremely fair on pricing. Yesterday I flew in to Denver and took an uber to pick up a bus I had purchased at Ritchie bro s. The original plan was to for me to replace the batteries and then transport the bus to his shop. When arrived with the two batteries to replace the dead ones one of the bolts had broken off and to my horror the posts on the batteries were not compatible with the cables. I decided to go to the local auto parts store to get post adapters but there was no ride-share service in the area. I called Kacey at twin peaks diesel and he didn t just give me advice. He left his home drove by the auto parts store and picked up and dropped off the adapters to me! He then helps me replace the two 127 lbs batteries and remove the broken bolt. It turns out there were also fuses blown on the bus that I didn t have time to deal with and still catch my flight so he arranged to send a technician out in the next two days to get the bus running. After all of that he gives me a ride to the nearest place where I can call an uber to catch and make my flight. Kacey made a stressful day an exciting experience and put my mind at ease. Please give Twin Peaks Diesel your business I promise you won t be disappointed! The definition of above and beyond service!!!Service: General repairs & maintenance

Casey and the team are great. They do amazing work for fair prices without doing a bunch of unnecessary work. All of your factory work can be done by Twin Peaks for far less than what the dealerships charge and you can get in fast.

I broke down on the interstate passing through and had my pickup towed to this shop. The guys were extremely knowledgeable and did everything they could do to help me. I would recommend this shop to anyone. This is by far the best repair shop I've ever been too.

The team at Twin Peaks Diesel is the best. I've brought my 2005 Dodge Ram diesel here for years and they always provide quick and honest service. My truck still runs like it's brand new thanks to the team at Twin Peaks. I highly recommend them and wouldn't take my truck anywhere else for service.

Had taken my truck here due to some strange behavior including what appeared to be Turbo Bark and a popping noise in the exhaust. I brought it in expecting the worst with a blown head gasket. Casey and the crew at Twin Peaks ran test after test and came back to me with their results and walked me through everything. Long story short there was no issue with the truck (and its been running top notch ever since). The guys at Twin Peaks earned a customer for life due to their honesty and how straight forward they were during this time. The price for the diagnostic work was really too fair, they could have charged me a lot more and most places would have. Some other places might have charged me for an unneeded head gasket too. If you want a mechanic you can trust and who makes sure you know what needs to be done I would recommend going here to Twin Peaks.

Took 3 weeks for minor repairs. Very forthcoming with information I already had and have all around poor business practices and ethics. If you have a Hummer don't take it here, and anyone else try calling first and see how rarely they answer.

Twin Peaks Diesel did an injector swap on my 2003 Duramax that I've owned since new. They recommended Dynomite 50hp injectors and a Cat filter swap. Pricing was fair and I was impressed with their knowledge of the truck (it's a ZF6 manual and fairly rare) and didn't push anything, just their personal experience, knowledge, and facts. After extensive research I agreed to the injector upgrade and filter kit (which he installed at no extra charge since he already had it apart) and COULD NOT be happier. He said it would run better than new but honestly it's way smoother than new. The extra 50hp is absolutely noticeable, especially in the 2k-2800 rpm range. Can't verify mileage yet as this truck tows 90% of the time and I havn't towed but maybe a few short trips. I appreciate no BS shops that are fair on pricing, and so far cannot recommend these guys enough.

I brought my truck here to repair my ac system a month ago. Exactly a month ago. I dropped it off. Said take your time. I dont need to drive until Monday. That was on a Friday. They had the truck for nearly 8 hours. Called and said it was repaired. Charged us a bunch of money. Friday this week. My ac system stopped working. It broke agaim because their machanic didnt replace the hose they claimed they replaced. In stead what theu really did was take a smaller tube the size of the flow diameter of the original hose line and jammed it into the old hose line then clamped it down. This decreased the flow diameter of the hose by 80 percent. Every single hose around that hose burst at the same time due excess presure amd because those lines should have been replaced along with the one they lied about repairing. I drive a federally regulated commercial motor vehicle. You have to be fmcsa certfied to work on these trucks. Because we are putting our lives litterally in your hands. What did you decide to do with that trust... You lied and sent me off with a broken hose on my ac system. If its 105 degrees outside its 115 in the truck with no a.c. I could have a heat stroke amd plow this truck through 20 cars on the interstate with an impact force of 4.5 million psi. It will kill everyone involved. All because you lied about fixing a hose. We have to have ac systems fully functioning. It is a Federal regulation. Its to ensure that we as the driver are capable of physically amd mentally handling these trucks. What if your children were in the first car I hit when i blacl oit from a hear stroke, then you find out I had a heat stroke because you faked a repair job on my ac system and lied about it. Your family would be dead because of you. The accompanied image is the repair job you did. That I discovered after the lines around this all burst at the same time. That clear line is NOT THE RIGHT LINE NORE IS IT THE LEGAL WAY TO REPAIR A BROKEN HOSE.
