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 S&S Diesel Motorsport 14mm High-Pressure Stroker CP3 Injection Pump (CP3-CU-14) provides extreme fuel volume for maximum-effort street, sled pull, and competition drag racing builds. When pushing heavy fuel duration with large performance injectors and high-boost compound or large single turbochargers, factory and mild-upgrade injection pumps experience severe rail pressure drain past 3,000 RPM.

Built 100% brand-new from genuine Bosch 6.7L Cummins CP3 architecture—never a stressed remanufactured core—the CP3-CU-14 features an oversized 14mm stroke design that flows a monstrous 1,850 mm³/rev of displacement. This represents more than double the fueling volume of a stock CP3. Internally modified to maintain sustained, high-volume flow past 4,500 RPM without cavitation, this single pump effortlessly satisfies the fueling demands of competition trucks making up to 1,200+ rear-wheel horsepower, eliminating the added complexity, bracketry, and extra belts of dual-CP3 setups.

Key Features & Benefits

• Extreme 14mm Stroker Displacement: Delivers an immense 1,850 mm³/rev, supplying maximum fuel mass per pump revolution to sustain commanded rail pressure.
• Supports Up to 1,200+ Horsepower: Provides single-pump fueling capabilities capable of supporting aggressive competition tunes, massive injector nozzles, and high-boost air packages.
• Extended High-RPM Delivery: Eliminates the classic OEM 3,000 RPM flow tapering, maintaining solid fuel output up to 4,500 RPM.
• 100% Brand-New Genuine Bosch Platform: Built starting from brand-new OEM Bosch 6.7L CP3 castings and components; requires zero core charge or core return handling.
• Simplifies Fuel Systems: Achieves four-digit horsepower fueling from the factory gear-driven pump location without needing secondary belt-driven CP3 brackets.

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 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 Requirements: Built from the updated 6.7L Bosch CP3 casting, which places the low-pressure supply port on the side of the flange instead of the top. Installing on a 2003–2007 5.9L truck requires adapting the factory supply lines with high-pressure hose fittings or standard 6.7L-style fuel line adapters.
• Low-Pressure Lift Pump Requirement: To avoid pump cavitation and premature wear, an aftermarket low-pressure lift pump system rated at 200 GPH or higher (such as FASS or AirDog) with a minimum 1/2" supply line and draw straw/sump is mandatory.
• Tuning Requirement: Professional custom engine calibration (tuning) is required to properly scale the Fuel Control Actuator (FCA/MPROP) and rail pressure delivery maps.
