S&S DIESEL CP3-CU-SS NEW CUMMINS SUPERSPORT CP3 (6.7L-BASED) – 2003–2018 DODGE/RAM 5.9L/6.7L CUMMINS 24V

S&S Diesel CP3-CU-SS SuperSport CP3 is a brand-new, 6.7L-based high-pressure fuel pump engineered for rock-solid reliability and stronger output above 3,500 RPM—ideal for daily drivers, tow rigs, and street builds in the 500–550 HP range that want CP3 stability without the drama of a big race pump. Built from new OE cores and blueprinted to S&S standards, it’s a proven upgrade for 2003–2018 5.9L/6.7L Cummins common-rail trucks.

• New 6.7L-based CP3 architecture for higher output >3,500 RPM
• OE-level quality with S&S Diesel Motorsport calibration and QA
• Excellent drivability—supports tuned or stock injectors
• Direct CP3 replacement for 2003–2018 Ram 5.9L/6.7L Cummins*

Fitment

• 2003–2007 Dodge Ram 2500/3500 5.9L Cummins (common-rail)

FAQ

CP3-CU-SS is brand-new (new 6.7L-based unit), built and validated to S&S Diesel Motorsport specifications.

It’s engineered for strong output above 3,500 RPM and is a great match for ~500–550 HP street/tow builds while maintaining OEM-like manners.

Yes, but since all S&S Dodge/Ram pumps are 6.7L-based, minor fuel line clocking/modification may be needed on 2003–2007 5.9L trucks.

While not strictly required on every setup, a quality lift pump helps maintain consistent inlet pressure, protects the CP3, and improves performance—highly recommended.

Not required for stock trucks, but calibration can maximize rail control and drivability on modified builds.
