Diesel Kings,

21724 Cypress Rose Hill Road, Tomball, TX 77377

"The owner is a good man who’s very knowledgeable on diesel trucks. Quality work at fair prices done in a timely manner. These guys have my business from now on. Don’t waste your time going somewhere else. They’ve done great work on my 01 7.3, 04 6.0, 06 6.0, 12/24 valve and my buddy’s 97 7.3."

"JOSE AND LAZARO DO NOT STAND BEHIND THEIR WORK. I first took our 2006 Ford F250 Super Duty in because there was coolant leaking into the exhaust system. They fixed the problem, but the check engine light was still on. Jose and Lazaro said I needed to delete the EGR and replace the factory chip with a "Tune" chip, and this would allow them to turn off the engine warning. I approved this work, which created a new problem, the exhaust was now filling the cab! They said it was because the Turbo was now leaking, and had me replace it with a used Turbo from a wreck they had on site, which would fix it. However, the truck has no power, now, the turbo boost is less than 5 PSI, and the engine warning light is still on! I have been paying my bills along the way, and have now paid them several thousand dollars. They claim that they guarantee their work, but this is simply not true. I have brought the truck back in but was told to contact the owners, and so I called Jose and Lazaro several times leaving messages and texting them, but they do not return my message."

"This place goes above and beyond to help you out. They specialize in diesel but the work they do with mufflers and modifications for high performance there are no words to describe it. Good prices and fast services Jose and Lachy knows a lot about this business. Will recommend to anyone in a blink of an eye."

"I own a 1997 Ford F-350 7.3L, and I can honestly say that after I purchased this vehicle, these gentlemen/professionals have basically rebuilt the engine, corrected the mistakes of others, and have guaranteed their work for years to come. I will only use them in the future and suggest that you bring your diesel to them as well. You will not find a better mechanic team, nor will you find more honest mechanics. They are an awesome team of brothers and do fast, reliable and efficient work. Very knowledgeable and better priced for the work, than nearby competition. They are always my go to guys."

"Had my 2006 F250 towed in to there shop , would not start. They started to check it out right away. The owner was keeping updated of the progress via , text, phone, and pictures. They were quick on the repairs and more than fair with the price! I have use other shops before , but Diesel Kings I would rate them a 12 out of 10 . I will be having more work done there. a VERY Happy Customer !!!!!"
