Jeff P.

Jake and the crew are awesome to work with. They can handle anything from routine maintenance or mid to wild one-off builds. The team did a fantastic job customizing my truck. The truck gets compliments everywhere I go and performs equally well. Glad to finally have talent in Rock Hill that can support the truck enthusiast crowd.

I had my Rough Country leveling kit put on my 2016 4Runner by the team at State Line Diesel Performance LLC, and the guys did a phenomenal job. Jake & Dawson answered all my questions and took care of my car just a few hours after I dropped it off. I can’t say enough about their professionalism & their knowledge of the business. I couldn’t be happier with the end result, and I plan on using these guys for all my cars’ needs. Top-notch service!

I was having a fueling issue on my truck, and the guys over here at State Line Diesel Performance LLC did diagnostics and found I had an injector going bad. Their communication was great throughout the whole process. They are very professional and completed the work in a timely manner. Truck runs like a top again. Highly recommend this shop!
