Duramax 12mm Stroker CP3 - New LBZ based - (46% over stock displacement) CP3-DMX-12

Duramax CP3 pumps are built from brand new Bosch LBZ-based pumps, and then modified to suit various fueling requirements from 500 to 1,400 horsepower in a single pump configuration. Every S&S CP3 pump will have a data sheet in the box that is crucial for proper calibration.

S&S CP3 pumps are internally modified, besides just increasing displacement, to efficiently deliver fuel well beyond the peak RPM of most diesel engines. Why? Some competition engines need high-rpm fueling, so S&S makes it a standard. The competition CP3 pumps might not be for everyone, but they're a wise choice for those who want the best... and the data above backs it up.
