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 2003-2007 5.9 Stage 1 Cummins Performance Cylinder Head is designed to deliver increased airflow and durability without the added cost and complexity of an aftermarket intake.
Featuring 105-pound valve springs and a 5-axis CNC port job, this head significantly boosts intake flow from 155 CFM to 220 CFM, improving low-end performance, reducing boost pressure, and lowering EGTs.
Built on the foundation of the HP Reman Head, it includes new bronze guides, oversized hardened seats, and a high-performance CNC valve job for enhanced longevity and efficiency. Manufactured by DandJ Precision Machine, this cylinder head is a proven upgrade for both stock and performance-driven Cummins builds.
