Eric had us in and out in less than 5 minutes when the “big” shop told us they might be able to hook it up to the computer before the end of the day. Thank you so much Eric! You saved our Yellowstone vacation.

Just plain awesome service! Could not be happier.

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.

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.

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.

Amazing service there fast and precise and low prices

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.

They are very good, honest and professional guys!! Thank you for all hard work! I appreciate it!

Honest, friendly diagnosed properly and priced reasonably

They are very knowledgeable and professional.

I've been doing business with Twin Peaks on and off for 10 years. They've done motor swaps, in frames (rebuild entire motor leaving block in frame) AC repairs, steering gears, motor mounts, etc. on semis, never had to take anything back other than general maintenance issues. Competitive rates. I've referred several folks to them over the years, all positive feed back. Never had any light truck work done by them, but know people who have and positive as well. They've recently moved location, couple miles from the previous locale. Check'em out, you'll be glad you did.

I was having a problem with a used Powerstroke that I had recently purchased. Had it to a Ford dealer with the problem of loosing power but they could not find the problem, talked to a different Ford dealer and described my problem and the also had no idea what the problem could be. Getting frustrated with the Ford people that are suppose to know their vehicles, I took my truck to Twin Peaks Diesel and the problem was diagnosed within a day and back on the road within three days. Thank you Twin Peaks for such great service.

I had Twin Peaks Diesel do injectors on my Duramax and they layed out all the options, what they recommended and WHY, and prices for each option. Never pushed additional work and their prices were fair. Not cheap, not expensive, but very reasonable. Took their advice on upgrading injectors and fuel filter system (which they installed for free because he said " we already have that part off, it doesn't matter what we put back on" and after researching it was a necessary upgrade) and the additional power is obvious. Truck runs smoother and better than new. Very happy with the work, timeline, and the customer service.

I am happy with the service and results!

Having a fleet of trucks its hard to find someone I can trust that is looking out for me and not trying to nickle and dime me on every little thing. When I drop a truck off at Twin peaks Diesel I know they will do whats needed not what would make them the most money or try and up sell me on something that is not needed.

Very fast quality service could not ask for more

After being told by another shop that our 2009 F350 needed a new turbo, we brought our truck here (highly recommended by several friends) for a second opinion. Our truck did NOT need a new turbo, just a really thorough cleaning of the turbo and our truck was running fantastically! They finished the work when the said it would be completed! Overall a very pleasant experience. We will never take our diesel anywhere else!

Good local trustworthy shop

Just got my truck injectors done and TP took care of me once again.

TP has been my diesel shop for years and what I appreciate most is their care in diagnosing issues. They do not do repairs you do not need and double check you even when you are sure you know what the problem is. Sometimes they know better and it has saved me a lot of money over the years.

I took my recent purchase of a 2010 F250 to the Ford Dealer across the Highway (Interstate Ford) to have fuel filters replaced and asked that they check the Engine Block heater at the same time. When I picked it up I was informed my truck didn't have a block heater. I took it to Twin Peaks diesel to have an engine block heater installed, I was quoted a fair price. When I picked up my truck I was informed that they didn't need to install a heater, there was one already on the truck, they installed a new plug only. They could have charged me the price for a heater and installation knowing that Ford had already told me I didn't have a heater. Ethics and Honesty are a rare treasure. Thanks Guys! I will be having them do work on my F150 because I am impressed with the follow up, reasonable pricing and honesty. Teri

As ever Eric and team are friendly and do good work. Price was very reasonable. They even took my camper off the truck for an unplanned job. Work took a day longer than planned which is the only reason I didn't give 5 stars!
