About Red's Diesel & Auto Repair in North Little Rock, AR

Red's Diesel & Auto Repair is a diesel repair and performance shop serving North Little Rock and Central Arkansas. Founded by a technician with over 20 years of hands-on diesel experience, we specialize in American-brand trucks, performance modifications, and commercial fleet service. Every repair and upgrade we perform draws on decades of working with engines, drivetrains, turbo systems, and aftermarket components.



We recognize that your truck serves multiple roles—it's your work tool, your business asset, and often a source of personal pride. That's why we take a consultative approach to every job. You'll receive clear explanations of what needs attention, realistic timelines for completion, and honest recommendations before we start any work. We don't push unnecessary services, and we don't surprise you with hidden fees.

Our focus is on long-term reliability rather than quick fixes. Whether you need routine maintenance, a complex engine swap, or a custom turbo installation, we perform every job with meticulous care. All our work is backed by a 12-month / 12,000-mile warranty, and we honor manufacturer warranties on all installed parts. When you leave our shop, you can trust that your truck is running better than when it arrived.

Complete Diesel Services From Maintenance to Custom Performance Builds

We handle the full spectrum of diesel and auto repair services at our North Little Rock facility. Our capabilities include oil changes and routine maintenance, engine repairs and complete engine swaps, turbo and twin-turbo installations, custom exhaust and piping fabrication, lift kits and suspension upgrades, drivetrain modifications, ECM programming, DEF system diagnostics and repairs, and paint and body work. Each service category requires different technical knowledge and specialized equipment—we've invested in both to ensure proper execution across all these areas.

We work extensively with commercial and fleet vehicles, supporting businesses in HVAC, plumbing, electrical, roofing, and service industries throughout Central Arkansas. Fleet managers face constant pressure to minimize downtime and control costs. We understand these realities and structure our service delivery accordingly—efficient diagnostics, realistic scheduling, and repairs performed right the first time. Whether you operate a single work truck or manage a fleet of commercial vehicles, you'll receive the same level of technical expertise and attention to detail.

Our shop is a trusted installer for high-performance aftermarket parts from Swap Shop, ARP Racing Products, S&B, AirDog, Wehrli Custom Fabrication, Fast Fuel Systems, S&S Diesel, Fleece Performance, and Yukon Gears. We don't just bolt on components—every installation follows manufacturer specifications and factory-level standards to ensure optimal performance, safety, and longevity. Performance modifications require precise calibration and integration with existing systems, and our two decades of experience mean we know how these parts interact and what adjustments are necessary for reliable operation.

Precision Work Backed by Transparent Communication and Warranty Protection

When you work with Red's Diesel & Auto Repair, you'll notice the difference in how we communicate throughout the service process. We walk you through what we've found during diagnostics, explain which repairs address immediate concerns versus preventive maintenance, and provide written estimates before beginning any work. You make the final decisions about your truck's service—we provide the information and expertise to make those decisions confidently.
