Testimonials

On 9/3/2026 Ryan Gunning had this to say:
Highly recommend Supreme Diesel Performance in Jacksonville. I was having an injector issue with my 6.7 Power Stroke and they were able to get me in the very next day. They properly diagnosed the issue, ohm tested the injector, confirmed it was the problem, and got it replaced quickly. I normally do my own engine work, but I’m traveling right now and don’t have access to all of my tools. Because of that, I’m pretty particular about who I let work on my truck. The owner was extremely friendly and informative, took the time to talk shop with me, and explained what they were seeing. I never felt like they were trying to upsell me or throw unnecessary parts at the truck. They also have parts in stock. Really impressed with the honesty, knowledge, and quick turnaround. It’s hard to find a diesel shop you feel comfortable trusting, and these guys earned my business. I’ll definitely use them again whenever I’m in the Jacksonville area.

On 9/2/2026 Johnny had this to say:
After dealing with Dealerships I decided to give a try to SDP, I needed to check my diesel fuel tank for rust contamination, Dealership show me rust in my filter, and I wanted to replace my CP4 with a DCR pump. This guys did an excellent job and got it ready on time like they promised. Also they show me some pictures of the fuel tank where you do not see any rust. I will have to say that was honesty. I believe that when I decide to install a 56 gallon fuel tank they will get that job. I am please with the job done on my 2014 F 250 SD.

Chevy 2500, 2020. I was at the dealership 3 times and kept getting dismissed with subpar results and codes that kept coming back. With 50 miles to go before power restriction i made the call to Nick. He said "I got you, bring it in." He said give me 3 days and ill have you going. I thought that was optimistic but i told him to do what it takes and he did not disappoint. It was ready before his goal and i couldn't be more satisfied. Great guy and great team. I'll never go anywhere else. If you have truck problems this is where the locals go! Thank you for your help!

On 8/3/2026 Earl Semadeni had this to say:
Absolutely blown away! Drove in to town (from about 9 hours away) to buy a used excursion - Called these guys to see if they could look at it for me, same day/no notice. Victor was absolutely outstanding, made it happen, the inspection was beyond thorough and they obviously know what they're talking about. Was also able to meet the owner (Nick) - same read: extremely knowledgeable, kind, and very customer focused. He's obviously build a great team and top-notch business! Quick turn around, excellent customer service, and obviously extremely good at what they do. Wish I lived closer so I could bring all my trucks to them!

On 7/24/2026 Aaron S. had this to say:
I had a great experience with Supreme Diesel Performance. I brought my 2011 Dodge Ram 2500 to them with a mechanical issue and only 48 hours before I had to leave on a cross-country trip. They quickly diagnosed the problem, worked with my tight timeline, and went above and beyond to get the repair completed before I left. The price was fair, the work was excellent, and the customer service was outstanding. They really understood my situation and made it happen when I needed it most. I'll definitely be bringing my truck back for future maintenance and repairs. Highly recommend!
