About State Line Diesel Performance LLC, Charlotte, NC

Stateline Diesel, I found them on Google. I contacted them through their website. It took about six weeks for them to get back to me with an email. At first, I was a little nervous about that. But after going to their shop I realize why it took them six weeks to get back to me. They are very busy. Which is a good thing. Because that means a lot of people use them and they do good work. It’s a bad thing because when I drop my truck in the shop. I wanted to get done quick because I was excited to get my truck fixed and back up and running. Jake and I talked about what we needed to do that will make it run better, and more reliable. After talking to him, I realize he really knew the ends of out’s of everything that can cause issues letter down the line. He offered solutions that will help the truck last longer and run better. While I was waiting on my truck to get worked on, I spent a little bit of time just walking around and observing how they operate. I noticed that there’s shop is kept clean even though they were overflowing with trucks lol. And the front lobby was kept clean. Had a nice couch to sit on to relax and a TV that I could watch. I also noticed how the employees communicate to each other. And it seems like everybody was on the same page. Even tho they were running 100 miles per hour. Overall, a great company to get service, repairs, and customization done. That will fix known issues that will make your investment run better, and last longer.

Jake & his team were so helpful with my personal company truck. We’re very informative throughout the process each time we touch base & they reached out. The truck drives as if it’s brand new, so smooth & the steering is much more stable now.

Thanks State Line Diesel Performance!

My truck: 2017 F250 XLT (2wheel drive - gas)

Needed an oil change on my F250. The guys got me taken care of. Good service.

Got 4 new tires and excellent service from here. I highly recommend.

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

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.

Had some issues with the truck while traveling. They got us in, did the repairs and we were back on the road the same day! Thank you!

Service was great, prices were great, and the information provided was even better. Will be returning.

I've wanted to find a reliable diesel repair shop for my 2001 F350 7.3 PS for routine maintenance. While preparing for my annual cross country camping trip my transmission decided to dump some fluid in the driveway. Much better to happen here than in the rockies imo. My search for a local repair shop led me to State Line Diesel in Rockhill, SC despite being a hour away and after meeting Matt and seeing the shop I know I made the right choice. To some, the facility may look in disarray but as an aircraft QC supervisor I found it organized and staffed with experienced techs who actually care about their work and helping others. I would highly recommend anyone needing diesel maintenance to check out State Line Diesel. Their attention to detail and the special projects they build and sponsor convinced me I've made the right choice.

I'll update my post after my truck is completed (diesel truck repairs take time) and I'm back on the road. These guys are definitely worth your time and business.

Honest review. Turbo replacement and new boost tubes added/grid heater delete.

What i liked:
They were able to get me in quick and worked with me on a timeline to get me on a trip. I believe that they know what they are doing and have the experience to handle issues with vehicles. They even put on new parts that had provided within my timeframe which is something that is hard to find. They are straight forward also which I think is a positive.
What I wished were better:
Communication of when things got in since I was on a time crunch and needed to know what I needed to do for my trip. The work performed was not complete once I got the chance to look at things, I found that my grill was not fully in place and none of the screws were tight, they were on but not secured. Once I got into the truck, new codes were introduced after the work was done but original code was gone. Come to find that the MAP sensor was never plugged back in causing them. I check the fitment of the parts, one of the couplers looks like it is out of the clamp allowing an air leak. Looking to the turbo itself, it is a brand new upgrade that comes with the a new actuator with it, now either it got some dirt in the time that I have had it or it is actually the original one that I had an issue with before which prompted me to come here. I cannot confirm that but it is working so I assume it is the new one, considering. These things are fixable but were overlooked, especially with coming out of repairs with new codes I figured there would be more commitment to service. They also kept my old parts that I provided so no core necessary.

Overall understanding all of this, I still would recommend and come back here for my bigger issues. Things happen but they are good at what they do and get you back on the road!
