Engineered specifically for 2004.5 through 2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L 24-valve common-rail Cummins turbo diesel engine, the BD Diesel Stage 2 Performance Fuel System Package (1051506) pairs a high-output 12mm stroker CP3 injection pump with a balanced set of flow-matched Stage 2 performance common-rail fuel injectors. Designed for owners seeking significant horsepower gains without external modifications, this package drops right into factory locations and retains a completely stock appearance under the hood.

The centerpiece of the kit is BD Diesel’s modified 12mm stroke CP3 injection pump, engineered with upgraded plungers that deliver up to 5.25 liters per minute (LPM) compared to the stock pump's 3.05 LPM output. The pump features an advanced heat-treated camshaft shaft material yielding 9x greater fracture toughness than factory designs to ensure long-term reliability under heavy load. Paired with a set of six precision extrude-honed common-rail injectors, this package ensures consistent high-pressure fuel atomization, improved in-cylinder combustion efficiency, crisp throttle response, and lower exhaust gas temperatures (EGTs) across the entire RPM range.

Key Features & Benefits

• Complete Matched Fueling Solution: Eliminates the guesswork of balancing injection pump displacement with injector nozzle size by pairing a 12mm stroker pump with calibrated injectors.
• High-Flow 12mm Stroker CP3: Delivers 5.25 LPM of fuel flow (over a 70% increase compared to factory 3.05 LPM) to hold commanded rail pressure under full load.
• 9x Fracture Toughness Shaft: Upgraded shaft alloy and proprietary heat-treating process yield 9x greater fracture resistance against torsional fatigue.
• Extrude-Honed Stage 2 Injectors: Genuine OE nozzles are precision extrude-honed to optimize fuel spray atomization, lower smoke, and manage EGTs.
• Factory "Sleeper" Appearance: Both the injection pump and injectors install in factory mounting locations, maintaining a clean OEM engine bay look.
• Tested & Calibrated: Built to OE clean-room assembly standards and flow-balanced on computer-controlled test benches to ensure equal cylinder-to-cylinder fueling.

Vehicle Fitment & Technical Installation Notes

• 2004.5–2007 Dodge Ram 2500 – 5.9L Cummins 24V Common-Rail Diesel
• 2004.5–2007 Dodge Ram 3500 – 5.9L Cummins 24V Common-Rail Diesel
• Fits Model Years: 2004.5, 2005, 2006, 2007
• Fitment Notice: Engineered specifically for 2004.5–2007 "Late" 5.9L Cummins engines with the factory 325 HP / 600–610 lb-ft rating and matching injector spray angles. Does not fit earlier 2003–2004 "Early" 5.9L engines due to piston bowl and spray angle differences.
• Fuel Supply Requirement: An aftermarket lift pump system rated at 150 to 165 GPH or higher (such as FASS or AirDog) is mandatory to provide adequate low-pressure supply volume and prevent pump cavitation.
• Tuning Requirement: Custom ECM calibration is required to properly scale fuel delivery tables and maximize horsepower output while controlling EGTs.
