Sims Diesel Technologies

Been taking care of both of my diesel vehicles for over a year. Love how professional and clean they keep the shop. Not the cheapest but I don't mind paying for experience and good service. Would recommend.

That take excellent care of Sarge. Always satisfied. The owner and everyone there are personable. Thank you Sims.

Cody & Spencer are awesome! I had issues with my DEF/emissions system on my '15 Duramax on my way to Murray, KY from MI. The guys were cool to work with, and extremely helpful. They were able to get my truck tuned & deleted faster than I expected. So very happy with the work they did! Thank you again!

Spencer was recommended to me after a shop here in Louisville failed to find the problem. I basically knew it was a bad injector already. Spencer found the bad injector and now my Duramax LLY runs like it should. Spencer gave me an alternate estimate to also upgrade some of the mods that I already had on the truck. I allowed him to go ahead and do them too. It was worth the drive from Louisville to have Spencer and his guys do the job instead of some shop that could care less about your truck, just to get the money. I have a 2018 Duramax also and hope if anything goes wrong with it under warranty, Spencer could do the work instead of me having to take it to a GM dealer that usually has no idea what they are doing.

The work at this shop was top notch! The work was completed at the price quoted, the performance of the work has exceeded my expectations and most of all, the Customer Service for INCREDIBLE! It was great to work with a company that understands how to treat customers in a way that makes them glad they spent their money there. I will use this company for all my diesel engine work.
