Supreme Diesel Performance

They all was great to work with.The whole team.Very helpful .I will be happy to be a repeat costumer.Thanks for all the hard work installing my new mower.

To start, I’m not from the area but I have been on the look out for a specialty diesel shop to take care of my truck for the time I would be living here in Jacksonville. I had a couple of concerns about some noises the front end on my truck was making which expedited the process of me finding a good, reputable shop. I decided to give SDP a call and spoke with Vic who was concerned and insisted that I bring my truck in that day. He and Nick were extremely accommodating to my schedule and were able to look at my truck and solve the issue that night, and I left super thankful that they had found

I really hate leaving negative reviews but I believe this is warranted. On 10/4 my partner was in Jacksonville for work and our f350 would not crank. We read reviews and supreme had the best ones so we had the truck towed there. They were super nice and on 10/6 the truck was ready and we were told there was air in the fuel line and they got it out.… Cost was $400 and change and we were out the door. My partner called me one mile into his 179 mile drive home and said that something wasn’t right. The truck was running awful and he wasn’t sure how far he’d make it. He white

Great owners! Awesome shop to get your diesel work done. Wouldn't go anywhere else.

For my wife and I, our truck is another member of our family. You cannot separate us from our 'BigBadWolf' and just like any special member of our family we want nothing but the best for it's care. It is very hard to find a mechanic that we can trust. My wife came across Supreme Diesel Performance and decided to give them a try based on the excellent reviews they have received so far. It took no time to realize that the reviews so far we're on point. We were very impressed by the knowledge that they have in diesel motors and the professionalism and integrity the crew had throughout the process

This is the best family owned diesel shop I have been in. They repaired the DEF system on my 2013 ram 2500. They set a very reasonable price and stuck with it... would not take a penny more even though they did more than anticipated. We were on the road and stranded and treated like best of friends or next door neighbors. Wishing all the best for your business

The crew at Supreme Diesel are top notch. They truly put their customer’s first and do everything they can to make sure you are taken care of. I needed my truck back on the road for a work trip, Nick and his tech (sorry forgot his name) made sure it happened for me. This is the only shop I will take my Duramax to. They are very knowledgeable and straightforward. Thank you Nick, Brandon, and the rest of the Supreme Diesel team! Appreciate all y’all do!

Absolutely best customer service.. Nick is top notch just picked up our dodge Cummins work truck and runs like a dream can't wait to get my personal 2020 into him to do work on. I recommend you give nick a call for all your diesel engine needs best out there by far...

When I took my truck to Supreme Diesel everyone was really busy. Brandon was first person I spoke with. He listened while I explained what my truck was doing and instead of just telling me we need to do this need to do that. He set me up an appointment to get a thorough inspections. I was late for that inspection and he still made time for my truck needs. He walked me thru everything he thought my truck needed. Gave me a few different options with different pricing. Great plan with a fair price. It was the outstanding customer service sold me from the beginning. Thanks Brandon, Nick and your wonderful

Took my truck to Supreme Diesel ! After speaking to Nick on a few different occasions I decided to upgrade my performance! Man I wished I pulled the trigger sooner. Top notch facilities,extremely knowledgeable,no pressure sales.He just tells you what’s best for your truck and was spot on. He even fixed a few things without even charging me a penny more. I wild definitely recommend them to anyone!

Great experience with these guys and I would highly recommend them to anyone with a diesel. These guys are great and really know their stuff. They took the time to explain to me (since I’m not a mechanic by no means) what was recommended and how everything worked. Got the job done in no time at all and even cleaned up the engine bay for me. Five stars all around.

Awesome work done at a great price. Great communication and made suggestions for immediate need and long term repairs for my stock 6.0 Super Duty. They really brought my truck back to life with a turbo rebuild, oil cooler replacement and a custom tune and it runs great! Highly recommended. Thank you!

Best customer service. Brian and the guys are genuinely good people and won’t sell you anything you don’t need. No up sales or trying to take advantage of you. They listen to how you want YOUR truck and do their best to make it reality. They have my business for as long as I’m in Jacksonville.

Nick and Brandon at SDP were great to work with while dealing with my 6.7. Nick walked me through every piece of what needed to be done to the truck and made it run better than it ever has. Thanks for the great work! Only place I’ll recommend in this area for reliable honest work.

Picked up my Duramax a few hours ago and I couldn’t be happier! Brandon, Nick and the girls are all great to deal with. My truck is running and performing great. The guys even took the time to detail the engine bay, it’s never been cleaner. Brandon hand made all new wire loom because the old stuff was wore out and he wanted it to look good. I won’t let anyone else touch my truck!! If you want to get some work done these are the guys!!

I had experienced major issues with the local Dodge dealership and was referred to Supreme Diesel Performance by another shop. My 96 Cummins had over 350,000 miles on it, had a leaking head gasket and valve… covers. In fact someone had over torqued a head gasket bolt and broken it off. They were able to get the bolt out and the work they did was amazing, the engine is sparkling clean, funny to say that about a diesel, and it now runs like a champ. I feel like I have a new motor again. I would recommend them to anyone. Their communication with me during the process was excellent, they called

Doug stewart 1 review just now Words can’t express how pleased I am with everyone at Supreme Diesel Performance. Kristen, Nick & Brandon did an excellent job diagnosing and repairing the issue with my truck. My engine looks and preforms better than the day it came off Ford’s assembly line.
