Engineered specifically for 2003 through 2018 Dodge Ram 2500, 3500, 4500, and 5500 trucks equipped with 5.9L and 6.7L Cummins 24-valve common-rail turbo diesel engines, the BD Diesel R900 12mm Stroker CP3 High-Pressure Injection Pump (1050551) supplies the extreme fuel flow required for high-output street, towing, and competition applications. When pushing past 500–600 horsepower with aggressive race tuning, compound turbochargers, or large injectors, factory injection pumps drain rail pressure at wide-open throttle (WOT).

The BD R900 pump solves high-pressure fueling limits by upgrading to a 12mm stroke camshaft paired with custom modified pumping plungers. This re-engineered stroke increases fuel displacement up to 5.25 liters per minute (LPM) compared to the factory 3.05 LPM output—a massive 72% increase in delivery capacity. Built with an upgraded shaft alloy and a specialized heat-treating process yielding 9x greater fracture toughness than stock, the R900 resists the torsional shock loads that cause shaft shear on standard stroker pumps. It mounts cleanly into the factory gear-driven engine location to retain a clean "sleeper" look while effortlessly sustaining commanded rail pressure for builds producing up to 800 rear-wheel horsepower.

Key Features & Benefits

• High-Flow 12mm Stroker Displacement: Delivers 5.25 LPM of fuel flow (versus 3.05 LPM stock) to prevent common-rail pressure drops under full load.
• 9x Fracture Toughness Shaft: Upgraded shaft alloy and proprietary heat-treating technology provide 9x higher fracture resistance against fatigue and shear failure.
• Supports Up to 800 Wheel Horsepower: Supplies ample high-pressure volume for upgraded common-rail injectors and high-boost air systems.
• Factory "Sleeper" Appearance: Retains OEM exterior dimensions and drop-in mounting, keeping high-performance fueling discreet under the hood.
• Enhanced Fuel Atomization: Sustains full target rail pressure to ensure fine fuel droplet atomization, lower smoke, cleaner combustion, and reduced exhaust gas temperatures (EGTs).
• Precision Bench-Tested: Assembled in clean-room facilities and calibrated on computer-controlled test equipment to ensure balanced output across all pumping chambers.

Vehicle Fitment & Technical Installation Notes

• 2007.5–2018 Dodge Ram 2500 / 3500 / 4500 / 5500 – 6.7L Cummins 24V Common-Rail Diesel (Direct Bolt-On)
• 2003–2007 Dodge Ram 2500 / 3500 – 5.9L Cummins 24V Common-Rail Diesel (Requires Low-Pressure Line Adaptations)
• Fits Model Years: 2003, 2004, 2004.5, 2005, 2006, 2007, 2007.5, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018
• 5.9L Installation Note: The R900 is engineered around the updated 6.7L CP3 pump architecture with the fuel supply port positioned on the side of the flange. When installing on a 2003–2007 5.9L truck, the low-pressure supply routing must be adapted with flexible fuel line or 6.7L-style line fittings.
• Lift Pump Requirement: An aftermarket electric fuel lift pump system delivering a minimum of 150 to 165 GPH (such as FASS Titanium or AirDog II-5G) with 1/2" supply plumbing is required to supply continuous positive head pressure and prevent pump cavitation.
• Tuning Requirement: Custom ECM calibration is required to properly scale the Fuel Control Actuator (FCA) duty cycles and optimize rail pressure ramp rates.
