After getting screwed over by someone that was supposed to fix my truck, they got my truck in and done in 2 days after sitting at another shop for a month.. great fast work!! Highly recommend

Was easy to order, part came a few days later and works good, highly recommend this company and will be ordering injectors soon.

I always had my cummins serviced at Duernberger Diesel Service. Never once was I disappointed in the service provided, communication was always top notch, and the work performed was top notch. Highly recommend them for all your diesel needs!

Great service, product as described. Fast shipping! Wonderful after sale service, would purchase from again

This company is beyond amazing, they put me on their schedule 📅 so quickly. I had my only business vehicle, a 2006 2500 Dodge Ram 5.9 diesel truck, towed in by AAA at the same time freaking out about how I'm going to run my business without a working truck. 🤯 KD Customs looked at my truck in their shop in Iron Ridge and within a couple of days gave me a very reasonable price! 🤯 In that same week, they replaced my injectors and other parts needed to make my truck run like new. My truck runs like it's brand new! Thank you so much 😁 Joey from Contractors Unlimited LLC

Great company with awesome customer service, parts, and overall experience. KD customs built me a P7100 injection pump and 5X.022 injectors which were very affordable and completed in a reasonably timely manner. Highly recommend KD for any diesel needs.

Only shop that had the part I needed..Spoke with Eric, super friendly and knowledgeable.. Fast, free shipping..Will definitely do more business here, in the future. Highly recommended

Super good guys, very knowledgeable! They take the time and do stuff right. Also super fast on getting parts in with a competitive price. Can't go wrong!

This company was fast and easy to deal with. We ordered parts for our business truck and couldn’t be happier with the service and shipping time.

Eric, Kyle and the crew at Duernburger Diesel / KD Customs are true professionals. I have had my Duramax worked on for both service & repairs as well as significant upgrades including injection pump replacement. They are upfront with pricing and provide a detailed quote, and they complete the work on time and above expectations. I wouldn't trust my truck to anyone else. I cannot recommend Duernberger Diesel enough.
