DNR Customs

DNR customs is second to none. I had Derek put a HD Tow Plus 68rfe transmission, install Hamilton flat tappet conversion, as well as a coolant bypass in my 2020 ram 2500 Cummins. Derek also diagnosed my front end issue, finding bent components, while other shops said my front end was fine. I am beyond impressed with their ability to handle the job, keep me well informed, and get me back on the road in less than a week and a half! My truck runs, sounds, hauls better than it ever has before and I couldn’t be happier hauling my 8,000lb work trailer every day. Derek’s tuning, knowledge of Cummins motors/transmissions, and customer service is the absolute best in the business. I would highly recommend DNR Customs!!

Derek and the guys (and gals) at DNR customs always go above and beyond making sure everything is done right the first time. Fair pricing and top notch workmanship. Attention to detail is outstanding as well. They even went as far as putting my manual adjusted seat back to as close as they could to how I have it. Will definitely be using them for all my trucks needs and wants.

I got my truck done a couple months ago and I wanted to wait to write my review. I got a turbo actuator done on a 2018 Dodge Ram cummins and it’s been running and driving flawless! I’d never take my truck anywhere else, Derek and his guys are awesome and do phenomenal work.

This shop is superior in every way when it comes to skill, knowledge, and integrity. Derek and his team have always got me up and running again with no issues. I put 5k miles on my truck a month at least and DNR is a critical component in my keeping both of my work trucks operating when they fail. Just today which prompted me to do this review. he made a miracle happen IMO. My trucks front drive shaft blew apart. I was able to limp it to his shop. DNR got me going again like I was in a NASCAR race. just pulling into the pits for repair... and within a small amount of time i was back on the road working again today lmao. THANKS AGAIN DNR CUSTOMS!

Thank you to Derek and the guys in the shop. They did an awesome job on my truck. I recommend them to anyone who needs diesel work completed. Great service and great people!
