Kyle runs a business that is second to none. Very professional and does exceptional work, not to mention a very clean and organized shop. The work was done as promised and on time. When I arrived to pick up my engine block and heads, they were wrapped and secured to a pallet to ensure safe transport. Well done.

I just ordered from Duernberger for the first time, they had a bracket in stock I've been searching for, the price was more than fair. My parts shipped quickly and arrived exactly as they were advertised. I will be ordering from them in the future.

Brought a Cummins engine block and cylinder head in for machine work, beyond satisfied! I m picky to say the least and everything came back looking great! Machine work was completed on time and is top notch! Also ordered parts for this engine after machine work was completed. 12/10 this is the place to go. Parts arrived on time if not ahead of schedule. Professional and friendly staff, Kyle and Eric are great to work with, I will be continuing to use their machine shop and parts services.Thank you!

There is a good reason these guys have 5 stars and 100 reviews. I have a 2013 ford f350 powerstroke, and I bought online, S&S fuel rails, and immediately after placing order Eric called me and told me they were on back order and that the Motorcraft rails that they have in stock is the same exact thing but for cheaper. I appreciated that so much that I went ahead and ordered the S&S 30% over fuel injectors from Eric as well. The fuel rails shipped the same day. But of course the injectors have to be built. I understand that. But after almost 4 weeks and still havnt got a valid tracking number Eric contacted S&S and figured out that S&S had made a mistake on the order/shipping. So they made a new order number and Eric covered next day air shipping for me. It wasn't KD Customs fault but he went ahead and covered expedited shipping anyways. That was an awesome thing to do since my truck is down right now. I will definitely do business with them again. Thanks again Eric! You rock!

Have always taken my truck here and have never been disappointed with the work. Eric and Kyle always go above and beyond to make sure everything is done properly and timely. Highly recommend KD customs for any work you may need.

On time with any service preformed, no added costs from quote and most importantly they stand behind their work! Great Family ran shop!

Can't say enough good things. I purchased a 2018 Ram 6.7 Cummins and took it to DDS for an overall inspection. Being my first Ram, I wanted to make sure I wasn't missing anything. Kyle was great to work with being very transparent about recommendations and didn't try to oversell anything. We made some upgrades for the grid heater and Banks air intake along with replacing all the filters and fluids along with a few other maintenance items. Truck runs great and I have allot more confidence in it now. I highly recommend DDS and will be going back for future service needs.

Have had service and performance work done by Duernberger Diesel Service through the last several years, and these guys always take great care of our trucks. My father and I have taken our diesel trucks to them and we are never disappointed! From great customer service, to getting quality work done by their professional service techs. I d 100% recommend this family run shop to take care of any of your diesel needs!

I've got an older Dodge with some parts not available anymore. Eric and his guys were able to make custom parts to get my truck back on the road. They were also great at keeping me updated on costs and when my truck would be ready. A good experience and I will definitely use them in the future.

As a fellow mechanic I am very picky who works in my truck. So when a friend of mine referred me to duernberger because they do good work. I can say the work I had them do was done perfect, quick, and they kept me up to date on the progress with my truck. Awesome work guys!

Duernberger Diesel is my go to place for any diesel repairs and service. I've had several repairs done by them all in a very timely manner, with absolutely no corners cut. You can always expect the job to be done right the first time for a reasonable price.

I was looking to get my motor built in my Cummins and after speaking to Kyle I knew off the bat he was the man for the job! I had a rough idea of what I wanted and we worked together to make it happen! He made great recommendations and never steered me wrong! It was a great pleasure to work with these extremely talented and knowledgeable guys! Thanks again

Ordered a cp4 kit and was expecting it to show up in a couple weeks but it was delivered a lot faster than that. Customer service was fantastic. Getting a call to discuss the details of the order was very helpful. Will definitely choose duernberger again for anything diesel.

Always accommodating for the emergency service (I go to them for my field service truck). Sometimes more expensive than the competition, but the work is done right the first time with unbeatable timing! Great shop!

I was looking for a rare part for a fuel system build on my Ford Super duty 6.7L Turbodiesel. It was a hard-to-find aftermarket part to go on the fuel pump. I had ordered it from another vendor, and found out a few days before my build was scheduled at the shop that it would not arrive in time. The other vendor promised a delivery date, and sold me a part they didn't have, and had no idea when it would come back in stock or ship out. I started calling around in a panic, and the great crew at Duernberger Diesel saved the day!!!!! They not only had the part in stock, but overnighted it to me as well so I had it in time for the build. Even though it was like, a $75 part, it would have held up a project costing thousands, and I would have lost even more money having the work truck down and out. Having staff like Duernberger go out of their way to provide excellent customer service is getting more and more rare these days. But, it makes a difference. I'll never do business again with the previous failed vendor, who basically blamed their parts supplier and told me to go pound sand.Thanks again Duernberger, you guys are awesome, and I'll be back!!!

Excellent service!! I order the part I needed from another site and then got a back order notification so I found the part I needed here called to make sure it was available. I can t remember who I talked to but they were very professional and a huge help. I placed the order online with no issues and received it before expected which was a huge plus since I was in a rush for it.

Kd customs has always treated me great! The team members there are more than helpful with anything I ve needed from parts, to service, to a performance engine build for my pickup. I have no problem recommending anyone to them for parts or service!

I had to replace my bearings on my ram and they had the Timken bearings I wanted and needed to replace the old ones. Very helpful and got them out quick. I will definitely look for other things from yall to use on my truck. Thank you.

Kyle and Eric have done an incredible job building the best all around diesel shop in Wisconsin! They have done numerous jobs for me from a simple oil change all the way to building a complete competition sled pulling truck. They are the real deal!!

The first time I met with Kyle after having work done at Huckstorf diesel and I was disgusted with there work. Kyle took a look at my truck and found some issues and made my truck run the best it ever had. Most of the problems were in programming set up. I have used Kyle ever since. I would and have recommended his business to many people sinceThanks Fred

I have been using Duernberger Diesel Service for my last two trucks. They have performed many services from simple maintenance to complex repairs and upgrades on my vehicles. Without a doubt I can say that they are the most knowledgeable and customer oriented shop that I have been to.

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.
