On Highway


For decades, Western Branch Diesel has supported on-highway customers with the highest level of service, most advanced diagnostic equipment, best quality products and expertly trained technicians. You can operate in confidence thanks to our commitment to the life of your engine. It is our number one priority to lower your operating costs and reduce downtime by being there when you need us through our 24 / 7 road-side service fleet and at our eight full-service locations serving Maryland, Virginia, Kentucky, Ohio & West Virginia.

In addition to one of the diesel world’s largest parts inventories, we additionally support our on-highway customers through a full range of preventative maintenance programs, and a variety of training courses for Detroit Diesel & MBE engines, and Allison transmissions. Our mobile classroom allows us to offer you the convenience of training at our many branch locations, as well as onsite at your company.

Our on-highway customers have come to expect more from us than just the best service, and that’s why we’ve equally invested in ensuring our sales team for diesel engines and components is the most knowledgeable to be found in our industry. As a long-standing distributor for Detroit Diesel, MBE and Allison transmissions to name a few, we can supply and support almost any new or refurbished equipment need from an aftertreatment system to the most advanced and durable diesel.
