Engineered specifically for 2003 through 2018 Dodge Ram 2500, 3500, 4500, and 5500 trucks powered by the 5.9L and 6.7L Cummins 24-valve common-rail turbo diesel engine, the S&S Diesel Motorsport SuperSport CP3 Injection Pump (CP3-CU-SS) is the benchmark OEM-plus upgrade. Factory Bosch CP3 pumps suffer from internal flow bottlenecks that cause delivery volume to taper off sharply above 3,000 RPM. When paired with street performance tunes, heavy towing files, or stock-to-mild injector setups, this restriction leads to rail pressure drop, extended injection duration, and higher exhaust gas temperatures (EGTs) near the top of the gear.

Built 100% brand-new from genuine Bosch CP3 architecture—not a worn remanufactured core—the SuperSport pump features internal modifications specifically tailored to sustain higher output above 3,500 RPM. This sustained delivery ensures stable commanded common-rail pressure right through the shift points, comfortably supporting builds in the 500 to 550 rear-wheel horsepower range. Because it is assembled from brand-new factory components, there is no core fee, no core return shipping, and no risk of cracked casting fatigue.

Key Features & Benefits

• High-RPM Output Optimization: Delivers increased high-pressure fuel delivery above 3,500 RPM where factory CP3 pumps choke off past 3,000 RPM.
• Supports 500–550 Horsepower: Perfectly matched for stock trucks, street performance calibrations, and tow rigs seeking stable rail pressure without stepping up to a harsh-idling race stroker pump.
• 100% Brand-New Genuine Bosch Platform: Assembled entirely from brand-new OE components; requires zero core charge and eliminates core return downtime.
• Cleaner Combustion & Lower EGTs: Maintaining target rail pressure at peak engine speeds ensures fine fuel atomization, minimizing smoke output and controlling exhaust temperatures.
• Bench-Tested & Calibrated: Assembled and tested to strict S&S Diesel Motorsport tolerances, shipping complete with individual test validation.

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 Supply Line Adaptation)
• 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: Because the SuperSport is built on the robust 6.7L CP3 casting, the low-pressure fuel supply port is located on the side of the mounting flange instead of the top. When installing on a 2003–2007 5.9L engine, the low-pressure supply routing must be adapted using flexible fuel line or 6.7L-style fuel fittings.
• Lift Pump Recommendation: To maintain positive inlet pressure and prevent internal plunger cavitation under sustained high-RPM operation, pairing with an electric fuel lift pump rated at 100 to 150 GPH (such as FASS or AirDog) is recommended.
• Tuning Requirement: Custom ECM calibration is required to scale the fuel delivery maps and take advantage of the extended top-end fueling capability.
