Tim at this shop helped us when we were in a huge bind. We broke down halfway home to Florida and they were able to get us in and help right away, which was not expected at all. They were very reasonable and super friendly. I am thoroughly impressed and would recommend this shop to anyone!

Took my truck in for repairs and Tim and the guys did an awesome and prices were very reasonable. Tim is very knowledgeable and got the issue figured out quick and had me back on the road in no time!!

Tim did a great job, we had some time constraints and necessities that he was able to fit into his schedule! It really helps when your from out of town and can get great service just like the locals! Thank you for your great service!

Tim and the gang at Knucklehead are awesome. They are knowledgeable and fairly priced. Tim has always gotten me taken care of with all of the repairs and upgrades Ive needed to have done in a timely manner. Thanks Knucklehead!

Brian was so friendly on the phone and helped us out in a pinch. He got us in and fixed quickly as promised. Stand up shop!

Traveling home to Texas from New Hampshire. Developed a fuel leak . He was able to repair and get us back on the road within an hour. VERY responsible rates. Five stars arent enough!!!

NO real knowledge or skill. Just best guesses and throwing parts at a problem.

I had many problems with my 02 Duramax that many other mechanics misdiagnosed that cost me thousands of dollars. I took it to KnuckleHead Diesel Performance and they were able to fix it in a timely and cost-effective manor. They were very friendly and polite in letting me know everything done to my vehicle. The work was terrific and the experience was very pleasant. I would recommend them to anyone else looking for a great service or performance shop

The mechanics at this shop are nothing but truck enthusiast fresh out of high school kids trying to learn the trade. Dont take in big jobs if you dont understand the work and skill level they require. Had I known this ahead of time I wouldnt have let my wife drop my truck off and would have saved me over 4 thousand dollars. Three weeks of being out of my truck, calling daily for a status update meanwhile driving by after hours and seeing my truck in the exact same spot for 11 days and never touched. It was supposedly repaired, yet the issues at pickup were still there and I was told that they couldnt duplicate the problem. So you just swapped out a ton of parts in hopes to clear the issue, meanwhile all they did was clear some codes and swap some parts without actual diagnostics performed. Ive since had to go to the dealership and have been told someone tampered with my ecm. All to find out now I have to go through this whole process to get the correct reflash and hope my ecm is salvageable.

I was deployed and my wife and mother in law were left in charge of my truck. I was badly in need of what new injectors, or at least that is what I thought. Knucklehead gladly helped out and was flexible with my situation. They found that not only were my injectors bad, but that my CP3 was bad. Now my truck runs like a dream. Will always run to them first when I need help with my truck. 5 stars every day of the week!

We took our truck for the same problem twice and they charge us almost $1,500.00 and the problem was never fixed. they are very dishonest and RUDE! especially Nathan.

Extremely Knowledgeable. Very nice guys. They really know what there talking about.

Best in the business, They repaired my truck quick and right best prices honest people will be back!!

Cost me over 2k in repairs to supposedly fix a fuel issue. all for it to fail again within a few miles and have to be towed to another shop. Biggest waste of money, They dont diagnose anything but instead just throw parts at your vehicle and hope it fixes the problem.

Tim is a stand up guy got my duramax right in a good time he wont kill you on labor just a real good guy! Will do all my Business with mister tate and send friends his way thank you Knucklehead diesel performance!

Great service, great value and knowledgeable employees!

Great group of guys and great work done.

Professional Trusted service.

No one ever answers the phone.
