10/10 recommend this shop to any one needing diesel service or parts! Every time i have dealt with this business i have genuinely been impressed by their professionalism and their knowledge. These are my go-to guys for anything diesel!!

Do not do business with these people. I sent my friend with 3 Perkins injectors, that list for $47.00 with trade in. Diamond diesel did not quote job when asked and charged $500.00 when finished. He has since disputed the charge and is making arrangements to return them. When they heard of the dispute, they still wanted more than double the price for a reduced amount. Never again. Thank you for the reply. Please check out the rest of the internet

Dan is a good guy and great neighbor, I would trust them with our Mercedes sprinter for sure.

It was horrible service I took my turbo to my 2005 lly duramax there to be rebuilt I provided them the kit to rebuild it they did also I ended needing a vgt sensor and then they said after it was all rebuilt and I gave them 1000$ to do it they said they can’t warnty it they could have told me that first so I could have gotten there rebuild kit then the turbo blew up after 12 miles and I took it back and they said my motor is junk and the turbo sucked a piece of metal from it but I bought a used lly turbo runs awesome I’ve put 7000 miles on the truck since then so motor is not junk they just do bad work and don’t stand behind it I’d suggest having someone else rebuild your turbo wast of time and 1000$ that lasted 15 min

Amazing

Great
