Diamond Truck Service Inc. 458 West Dimond Boulevard, Anchorage, AK 99515

"I had some work done to my 1996 power stroke. I have never had bad service and will not go to another shop. Keep up the great service and they stand behind there work. Thank you Sean Foley."

"DTS is one of only a couple specialists in the area, they had a full shop and plenty of work, and they still went above and beyond to help me out of a jam with my 6.4 Powerstroke extremely quickly. The crew was very helpful and willing to go out of the way to take care of me through the whole process. The owner is very knowledgeable, open, and honest with advice even when it doesn't benefit the business directly. He and some of his crew were working late on a Friday to get people taken care of, and it still came in under the original estimate. He didn't try to upsell anything, went out of his way to accommodate my oversized vehicle, and gave sound advice on work I should get done in the future, even though I do not live in the area and wouldn't be getting it done with him. I would absolutely recommend this shop, especially if you have one of the famously picky newer Powerstrokes."

"If you’re looking for a shop that will unhurriedly throw parts at a problem with no attempt at diagnostics, this is the place for you! 2007 Duramax with intermittent Service Brake System warning message and lit ABS and Brake dash lights. Said they couldn’t read a code (it was in the historical record when I got home to my reader) and replaced a wheel speed sensor. Second time in, the next week, they said they couldn’t reproduce the problem even after I told them exactly how to do it (change the fan speed setting.) One of the owners scolded me for being there 15 minutes past closing when I arrived 45 minutes before the closing time shown on their website. Third time in, a couple weeks later when I could spare the truck, I took the dash apart myself, found a smoked pin on the connector to the fan speed selector, left everything open and dropped it off with a specific request to not just replace parts, because they are all expensive and I could do that; I am looking for diagnostic help, not just parts swaps. I purposefully waited to drop it off until they had time to attend to it immediately. They proceeded to keep it for four days and, after telling me there was no way to diagnose independent parts of the system, replaced three fan system parts, billed 2.5 hrs labor and charged me $1,100. The problem recurred before I had 50 miles on the truck. But hey, at least I got a mismatched dash component for only $513! I’d like to like this business but they’re just not leaving me much to work with here. I’m giving them the second star because at least I was able to get my truck back before weekends and the alignment they did after installing tie rod ends is almost straight."

"Made appointment to get some Banks upgrades on Cummins, overall experience 5/5 - Alex kept me informed of progress, the work is awesome, highly recommend. Foley runs a great shop, will be back."

"Honest, Experienced, Professional! Sean Foley and his team are some of the BEST DIESEL specialists I've ever encountered! I had been traveling across the country from Houston, TX in my truck camper and had many dealings with auto repair shops along the way who all claimed to be able to work on diesel trucks. Sadly, not all "diesel mechanics" actually know anything about diesel trucks and I could no longer afford to bleed money for inaccurate and subpar auto repairs! These guys have the knowledge and experience to custom build a whole diesel truck from bumper to bumper, if you needed. It wasn't until I met Sean, that I finally received the honest truth that the cost to fix the truck would be more than it was worth. In fact, I probably wouldn't have made it very far on my journey home and would have probably been stuck in the Yukon somewhere looking for a new engine. Sean saw that I was in a bind and actually took the time out of his extremely busy schedule to assist me in finding a replacement so that I could get back home. Thankfully, he was able to get me an UNBELIEVABLE DEAL for one of his trucks, in order to get me back on the road. He went ABOVE and BEYOND to make sure that I was taken care of and was completely thorough and professional through the whole process. I ended up leaving with a 2006 F250 that the shop outfitted to be able to mount my camper on, along with the confidence that I will be able to continue my road trip back to the lower 48 SAFELY. It has truly been a blessing to have stumbled upon Sean Foley and he has definitely paid it forward with his efforts! Eternally Grateful!"
