Engineered specifically for 2003 through 2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L 24-valve common-rail Cummins turbo diesel engine, the Dynomite Diesel Products (DDP) 12mm Stroker CP3 Injection Pump (NCP3-30412) delivers extreme high-pressure fueling for four-digit competition and max-effort street builds. Factory 5.9L CP3 pumps suffer from internal volume limits and flow tapering past 3,000 RPM, causing severe rail pressure drop under wide-open throttle (WOT) when running oversized competition injectors and high-flow turbo configurations.

Built 100% brand-new using the robust 6.7L Cummins Bosch platform—not a worn, remanufactured core—the DDP 12mm stroker supplies consistent, high-volume displacement that maintains commanded fuel pressure all the way to 6,000 RPM. Unlike modified pumps that rely on drilled or aftermarket fuel control actuators that lead to erratic rail pressure and idle surge, DDP retains a brand-new unmodified OEM Bosch FCA (Fuel Control Actuator) for clean idle characteristics and straightforward custom tuning. Capable of supporting over 1,000 rear-wheel horsepower, this pump ships complete with the necessary installation hardware to adapt the 6.7L casting directly into the 5.9L factory engine location with zero core charge.

Key Features & Benefits

• Supports Over 1,000 RWHP: Delivers the high-pressure fuel mass required to maintain target rail pressure on competition drag racing, sled pulling, and extreme street applications.
• Full Fueling to 6,000 RPM: Eliminates factory RPM flow restrictions, providing sustained fuel delivery across elevated operating speeds without cavitation.
• 100% Brand-New Genuine Bosch Casting: Built starting from brand-new OEM components, eliminating core return handling, downtime, and fatigue cracks.
• New Unmodified OEM Bosch FCA: Uses a stock-style metering actuator to prevent erratic idle surge, bucking, and tuning headaches common with drilled actuators.
• Includes 5.9L Adaptation Hardware: Ships with all necessary fittings and conversion components to adapt the 6.7L side-port pump architecture directly to the factory 5.9L location.
• Zero Core Charge: Sold outright as brand-new hardware, requiring no core deposit or return shipping.

Vehicle Fitment & Technical Installation Notes

• 2003–2007 Dodge Ram 2500 – 5.9L Cummins 24V Common-Rail Diesel
• 2003–2007 Dodge Ram 3500 – 5.9L Cummins 24V Common-Rail Diesel
• Fits Model Years: 2003, 2004, 2004.5, 2005, 2006, 2007
• 5.9L Conversion Notes: Because this unit uses the updated 6.7L Cummins CP3 platform for superior internal strength and flow, the fuel inlet is located on the side of the mounting flange rather than the top. All necessary conversion fittings and lines are included in the box to adapt directly into the factory 5.9L mounting position.
• Fuel Supply & Pressure Requirement: For maximum fuel delivery, pair this pump with an aftermarket lift pump system rated at 200 GPH or higher (such as FASS or AirDog) regulated strictly between 10 to 15 PSI. Critical: Supplying excessive inlet pressure to the CP3 can damage internal seals and cause severely degraded idle quality.
• Tuning Requirement: Custom ECM calibration (HP Tuners, EFI Live, or Smarty Touch) is required to properly scale pump displacement delivery tables.
