Description
The Bosch CP4.2 is known for failing without warning, and a failure can send metal through the injectors, rails and lines. The S&S Diesel Motorsport kit replaces the CP4 with a proven Bosch-based CP3 ahead of any failure.
S&S builds its conversion kits around a brand-new CP3 instead of a core-exchange pump, so there is no core charge and nothing to return.
Why we like it
- Failure-prone Bosch CP4.2 high-pressure pump replaced by a CP3
- Pump starts from a brand-new Bosch CP3, not a core-exchange reman
- Brackets, lines and hardware for a one-job swap are included
- Needs custom tuning to control the pump (competition version)
- Emissions: not CARB exempt. Limited to off-road or competition use on pollution-controlled vehicles
- Built for the 6.7L Cummins
What's in the box
S&S CP3 high-pressure pump with the conversion hardware, brackets and lines S&S packages for this platform. The S&S install guide has the full parts list. Quote part RAM-CP3-10HS if you call about this one.
Fitment
2019–2020 Ram 2500/3500 6.7L Cummins. S&S Diesel Motorsport part number RAM-CP3-10HS.
Install notes
Budget a full shop day. The fuel system gets opened and must be properly primed and bled afterward. Plan on custom tuning. Professional installation is the way to go. Check every fitting and line on the 6.7L Cummins before the first start.
California and CARB states: without a CARB exemption number, this part is for off-road or competition use only on pollution-controlled vehicles in those states. It does not ship to California.
