About Southern Specialized Truck and Trailer

We’re a diesel repair shop built on honest work, experienced technicians, and owners who believe collaboration and clear communication matter just as much as quality repairs.

Southern Specialized

Who We Are

Southern Specialized is a heavy-duty diesel repair shop in Lake City, FL, built on a foundation of quality craftsmanship and a deep commitment to our community. For nearly two decades, we have been the trusted partner for those who cannot afford downtime—including local businesses, emergency responders, and critical government fleets.

We believe in doing things the right way. Our technicians prioritize high-quality repairs and proactive maintenance to ensure every vehicle is ready to perform when it matters most. We view our work as more than just mechanical service; it is a way to support the businesses that build our local economy and the public vehicles that protect our neighbors.

By combining deep industry experience with streamlined, efficient shop operations, we provide a smooth, reliable experience from the moment a vehicle enters our bay until it is back on the road. At Southern Specialized, our pride in our work is matched only by our dedication to the community we serve.

How We Do It Differently

We believe good diesel repair starts with good communication. That means listening first, explaining clearly, and working with you—not talking over you or pushing unnecessary repairs.

Southern Specialized takes an approachable and collaborative approach to every job. You’ll know what we’re fixing, why it matters, and what to expect next. If there’s more than one option, we’ll discuss it openly so you can make the right decision for your truck or fleet.

We also stand behind our work with a 90-day warranty and use parts from trusted suppliers like NAPA, allowing for fast replacement if a component is ever defective. That commitment helps reduce repeat repairs and minimize downtime.

Our team is trusted by first responders, emergency vehicles, fire trucks, forestry equipment, DOT fleets, and government contracts, and we bring that same level of care and accountability to every over-the-road truck we service.

At the end of the day, we’re here to be a shop you can work with, not work around.

Customer Testimonials

Hear from our customers.

Excellent mechanic, reliable and prompt communication, excellent repair job at a reasonable price. Was kept informed during the process of a very involved fuel injector replacement on my F350. They called when they said they would, a rare occurrence in today’s business world. Found my new diesel mechanic!  Highly recommend!

We were having issues with our motorhome.  They allowed us to stay the weekend in their parking lot so that Monday morning they could check out our troubles.  They got us up and going and I would encourage anyone that's in the area, if you need truck or motorhome help, contact them. Thank you thank you thank you for your help.
