BD Diesel USA is a performance-oriented company specializing in high-quality diesel and heavy-duty truck components and upgrades. Their products are engineered to handle high pressure, high temperature, high load, and extended operation, not just occasional use. With years in the field (including intensive hours of idling, towing, and heavy usage), the BD Diesel's engineering and R&D is informed by real use cases.
The BD RoadMaster E4OD Tranmission is built for reliability and peace of mind. Designed for stock or mildly modified Ford Super Duty Trucks, the RoadMaster increases durability with a modified valve body. These modifications increase the clutch packs' torque capacity and converter charge pressure.
The Tranmission also receives a BD Diesel Deep aluminum pan, for an additional 6 quarts of fluid, helping to keep Tranmission temperatures cool while towing. Every RoadMaster E4OD Tranmission package includes a billet ProForce Torque Converter and is dyno tested before shipping.
