Product Description
S&S Diesel CP3-RR-10-HS is a reverse-rotation, high-speed 10mm CP3 built on a brand-new Bosch CP3NH base and optimized for mechanical/belt-drive and dual-CP3 race applications. Displacement: 1,325 mm³/rev (10mm). Engineered by S&S Diesel Motorsport for reliable high-RPM fueling in competition builds where the pump must spin opposite standard rotation and maintain rail pressure under sustained load.
Fitment
- Universal reverse-rotation applications (belt-drive/external drive, mechanical dual-CP3 brackets, competition diesel builds).
- Commonly used as the front, externally driven pump in dual-CP3 race setups for Cummins/Duramax platforms.
- Not a direct bolt-in for stock serpentine CP3 locations (reverse rotation & external drive required).
What’s Included
- 1 × S&S Diesel Motorsport CP3-RR-10-HS Reverse Rotation 10mm High-Speed CP3 (new unit).
- Bench test/data sheet from S&S (per S&S CP3 program standards).

- Competition/race use only where applicable. Verify series rules and local regulations before use.
FAQ
What’s the difference between CP3-RR-10 and CP3-RR-10-HS?The HS version uses S&S internal calibration/geometry targeted for high-speed operation, maintaining delivery at elevated RPM. Both are 10mm (1,325 mm³/rev), but HS is optimized for high-rpm fueling in competition use.
Is this pump a direct replacement for my truck’s factory CP3?
No. CP3-RR pumps are reverse-rotation and intended for external/belt-drive (or similar) setups. For OE-location pumps or conversions, see our CP3 categories and S&S conversion kits.
Do I need an additional lift/supply pump?
Many competition builds pair reverse-rotation CP3s with a dedicated mechanical supply pump (e.g., S&S SP3000) or a robust electric lift system. See our Dual CP3 & Components hubs for plumbing and supply options.
Can CPP help me size the pump(s) for my goals?
Yes—contact us with turbo(s), fuel, RPM target, and class rules. We’ll recommend 10mm HS vs 12mm/14mm HS, plus the correct supply, lines, and controllers.
