Fresno is the engine of California’s Central Valley, and if you run trucks here, you know the pace never slows down. From agriculture and cold storage to logistics and regional freight, every hour counts when a vehicle is down. That’s why Unified Truck Services, Inc. is proud to bring full-service mobile diesel truck repair and fleet services directly to Fresno businesses—so you can stay focused on getting the job done.
We’ve been in this business for over 35 years. We know the urgency. We know the demands. And we know how to keep trucks running strong in the heat, dust, and long miles that define the Central Valley. Whether it’s a single truck acting up or a full fleet that needs consistent attention, we’re here with the tools, knowledge, and mobile capability to make your life easier.
When you call Unified Truck Services, you’re not getting basic roadside help—you’re getting certified technicians who arrive equipped to handle real repairs. We work on-site, whether your truck is parked at your yard, stuck on the side of the road, or waiting to be loaded at a cold storage facility.
From diagnostic scans to hands-on repairs, our mobile truck repair units are ready to handle just about anything:
No-start issues and engine performance problems
Overheating and cooling system failures
Fuel delivery and injector issues
Electrical faults, sensor problems, and warning lights
Brake system repairs, including air brake systems
Battery testing and replacements
Transmission and driveline concerns
We’ve worked on Freightliner, Kenworth, Peterbilt, International, Isuzu, Fuso, and more. Our team knows diesel systems inside and out—and we make sure your repair is done right the first time.
We don’t treat you like a number, and we don’t leave you waiting around. When you call Unified Truck Services, you’re talking to real people who understand the pressure of keeping trucks on the road. We communicate clearly, show up when we say we will, and stay until the job is done.
We also believe in working around you—not the other way around. That’s why all of our services are fully mobile. You don’t have to pull trucks off the job to get them serviced. We come to your location, fully equipped and ready to work. That’s less downtime, fewer scheduling headaches, and more value for your business.
We’re proud of the long-term relationships we’ve built with Fresno businesses—trucking companies, agricultural suppliers, warehouse operators, and local contractors who trust us to keep their fleets moving.
