Rely on our experienced diesel truck mechanics to get you back on the road again in no time.

When your diesel truck starts making strange noises or a new warning light pops up on the dashboard, you’ll want to rely on an experienced and trustworthy diesel truck mechanic to get to the root cause of the issue. If you’re not sure where to turn to in the Charlotte, North Carolina region, we’d like to encourage you to visit our shop here at State Line Diesel Performance LLC. Our locally owned and operated business specializes in diesel truck repairs, maintenance, and customizations, and we’d be delighted to provide the comprehensive solutions you need to get back on the road again in no time.

If you decide to visit our local diesel shop, you’ll be greeted by one of our friendly and knowledgeable employees who will ask you what issues you’ve been noticing with your truck. Once we’ve collected some key information from you, a diesel truck mechanic will conduct a full diagnostic inspection of your vehicle. Rather than simply providing a temporary solution based on our initial assumptions, we take the time to ensure that we fully understand the problem so that we can permanently resolve it. This means a safer ride for you, fewer repairs for your truck, and greater peace of mind while you’re on the road.

Once our diesel truck mechanic has figured out the source of your vehicle issues, they will develop a tailored repair solution for you to review. Their estimate will include an approximate timeline, an upfront quote, and the pricing details for labor, parts, and other critical components. We’ll be happy to answer any questions you may have, and if you approve of the estimate, our diesel truck mechanic will start working on your vehicle right away.

Todd Hull

Jake’s team is awesome. Very knowledgeable and comfortable working on modded rigs. Would absolutely recommend them for anyone needing a good shop.

Jeff Schott

I was pulling my 5th wheel to Florida when I started getting engine light and trouble codes on my F350 dually as I was going through Charlotte around noon. I called State Line (15 minutes away and on my route) and Jake said stop in, we will look at it right away. There was plenty of room to back up my 5th wheel and unhook. Jake offered that we could stay there overnight if needed, he even offered to let us plug in for electric. They immediately diagnosed my issues. Jake communicated with me for approval and said they could get me back on the road before 5pm. We hung out in our camper and around 4pm Jake backed the truck up to our RV and said you're ready to get back on the road. I can't thank you enough for the immediate attention and getting us on our way. Overall wonderful experience with Jake and the team at State Line Diesel! We ended up making it to Fort Myers on schedule.

Donna Schott

Christopher Dix

I have a Cummins... they've helped me out a lot, they're good people and know what they're doing.

Elevate Media

I drive here all the way from Charleston because I know they'll take good care of my truck. It's more than just a truck and they understand it, any issue I've had with my truck they knew exactly what it was to fix it. So now they do all my diesel work, it's worth the trip for me.

Costan Bacogeorge

I do not usually leave reviews but I have been searching for a good diesel shop for years often leaving me to do the work myself.
Thankfully someone recommended me to Jake at Stateline.
They took my truck in, communicated through the whole process, and got my truck running better than it ever has.
I highly recommend Stateline diesel performance and will be returning in the near future.

Todd Gleason

Jake was fantastic to deal with, my daughter had an issue with her Ram Eco Diesel which was tuned already, being from
Canada and a long way from home I wanted someone I could trust to help her out and understood tuned trucks. He did what he said he would do, and did it well, no bullshit, highly recommend this shop for diesel or anything truck. If I lived anywhere near them I would be a regular.
