BD Diesel 03-04 Dodge 5.9L Cummins Stage 1 Performance CR Pump & Injectors Package

BD Diesel has been making performance diesel parts for decades, and this Stage 1 Performance CR Pump & Injectors Package for your 2003-2004 Dodge 5.9L Cummins is one of their staples. This setup is designed to give you a significant boost in fuel delivery and atomization without needing to overhaul your entire fuel system or run a dual-pump setup. It's a popular choice for owners looking for more power and better combustion efficiency, all while maintaining a stock appearance under the hood.

At the heart of this package is a modified CP3 injection pump. It features a 12mm stroke camshaft with upgraded plungers, increasing its output from the stock 3.05 liters per minute to a robust 5.25 liters per minute. The camshaft itself is made from a custom alloy steel that's significantly stronger and more durable than standard materials, offering nine times the fracture toughness to handle the increased demands. This means you get a consistent, on-demand supply of high fuel pressure, which leads to more efficient fuel atomization. This improved atomization translates directly into more power, better overall combustion, and lower Exhaust Gas Temperatures (EGTs), making your Cummins run cooler and more efficiently under load.

The included Common Rail (CR) injectors are also a key part of the performance upgrade. They are flow-matched sets that use OE quality nozzles. These nozzles are extrude honed to increase fuel flow and improve atomization, and the injectors are assembled and calibrated using OE procedures to ensure they perform perfectly. This package is capable of supporting up to 800 rear-wheel horsepower, representing a 72% increase in fuel capacity over stock. It's a well-built system designed for long-term durability and noticeable performance gains for your 5.9L Cummins.
