Diesel Truck Mechanic, Charlotte, NC

Great work done and they finished ahead of schedule to fit into our time frame. Thanks.

Professional, Knowledgeable, and Friendly!!! They get the job done right the first time and at a reasonable price. Thanks Guys!!

Had a great experience and highly recommend their services. Great customer service as well.

Very knowledgeable on trucks. Even though they normally work on diesel trucks. They worked on my Nissan Titan for some fab work on the mounting bracket for lower control arm. Looks like it never happened. They were able to keep their time line of 2-3 weeks for completion.

great place, good prices and easy to work with

We take our trucks there because we trust their work and they always communicate with us if they run in to an issue or if anything else needs to be done . Definitely recommend

After another shop worked on my 2024 Ford F-350 Super Duty, I ended up having to redo almost everything. Thankfully I found Stateline Diesel, and the difference was night and day. These guys actually know what they’re doing. They went through the truck correctly, fixed the issues the previous shop created, and made sure everything was done right the first time. Communication was great, turnaround time was solid, and the quality of work gave me confidence in my truck again. It’s hard finding a shop you can truly trust, especially with newer diesel trucks, but Stateline Diesel earned my business going forward. Highly recommend them to anyone needing honest, knowledgeable diesel work done right.

Jake and his team at Stateline Diesel Performance are First Class. They are very knowledgeable, detailed and transparent on everything.

I highly recommend this shop. Allow me to “highlight” Jake! He’s professional, knowledgeable, and attended to all my questions and concerns. Ultimately he delivered excellent customer service! -Russ R

I’m honestly surprised by some of the reviews I’ve seen, because my experience with State Line Diesel, their employees, and especially the owner has been nothing but positive. I’m a woman who drives a big truck, and for most of my life my dream was to own a monster truck! Now, at my age, I’ve toned it down just a bit—but not too much. I lifted my truck 8 inches, changed the tires to 37s, added rock lights, cab lights, grill lights, and new wheels. From start to finish, everyone at Stateline Diesel was incredibly kind, welcoming, and made me feel right at home. At the end of the day, this is an automotive shop. They’re not trying to win a Mr. Congeniality award—and frankly, I don’t expect them to. I don’t get offended by directness. What matters to me is being respectful, being professional, and doing quality work. Stateline Diesel is here to do great work on trucks, and that’s exactly what they did. If some people are upset about the owner’s personality, maybe that’s something they need to reflect on themselves. I’m far more concerned with skill, integrity, and results—and this shop delivers on all three. State Line takes real pride in their work, and if something isn’t to your liking, they make it right. I truly appreciate their honesty, transparency in pricing, and straightforward feedback. At the end of the day, this is a business—they can’t give things away for free. Quality work costs money, they need to pay their technicians, and truck upgrades don’t come cheap. But when you’re investing this kind of money, you want to take your truck somewhere that genuinely cares. State Line Diesel does exactly that, and I wouldn’t hesitate to recommend them!
