We offer heavy duty truck repair and fleet services designed for efficiency and durability. From routine maintenance to complex diagnostics and repairs, our certified technicians ensure your trucks, whether light, medium, or heavy duty, receive the highest standard of care right here in Maryland.

Our heavy duty truck repair services are designed for the largest and most robust vehicles on the road, including Class 7, Class 8, and Class 9 trucks. This typically includes tractor-trailers, dump trucks, refuse trucks, and other large commercial trucks. Common heavy duty vehicles we service are commercial trucks, semi trucks, 18-wheelers, refuse trucks, and dump trucks.
Medium duty trucks (Class 4, Class 5, and Class 6) bridge the gap between light and heavy duty vehicles. This category often includes box trucks, delivery trucks, larger pickup trucks, and other mid-sized commercial trucks.


While Eyre Heavy Duty specializes in larger vehicles, we also offer essential repair and maintenance for light duty trucks (Class 1, Class 2, and Class 3). This includes commercial pickup trucks, vans, and SUVs.
Common light duty vehicles we service include: full-size pickup trucks (e.g., Ford F-150, Chevrolet Silverado 1500, Ram 1500), cargo vans (e.g., Ford Transit Connect, Mercedes-Benz Sprinter), and smaller commercial vans.
