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 Heavy Hauler 6.7 Cummins Long Block is a fully assembled, high-performance engine solution designed for heavy-duty towing and work applications. Rated for up to 700 HP, this long block includes a DandJ Stage 1 High-Performance Cylinder Head, a street/towing camshaft for lower EGTs and improved fuel economy, and custom ARP 9/16 Inch head studs for superior sealing strength.
To enhance durability and reliability, this build incorporates 2018 and older components, replacing the less reliable hydraulic roller lifter setup with solid flat tappets and adjustable rockers. Each engine is CNC-machined, fully blueprinted, and assembled with premium components, ensuring maximum strength and longevity.
Manufactured by DandJ Precision Machine, this engine is built to outperform and outlast stock configurations in the toughest applications.
