Duramax 14mm CP3 High Speed (1 850 mm3 /rev displacement) New LBZ-based

The S&S Diesel 14mm High Speed Stroker CP3 Pump is a brand new LBZ-based pump engineered for high-performance Duramax applications. This pump is optimized for efficient fuel delivery beyond 4,000 RPMs, eliminating fuel flow restrictions found in stock CP3s at 3,000 RPM. It features an increased displacement of 1,850 mm³/rev and a peak output of approximately 450+ L/Hr at 5,000 RPM. Designed to support fueling requirements from 500 to 1,400 horsepower in a single pump configuration, each unit is fully tested and includes a data sheet for proper calibration. This pump is built from the latest generation Bosch CP3NH base. Custom tuning is required for installation on 2001-2005 LB7 and LLY engines, and LB7 installations specifically require modification of the regulator connectors. This pump can also be used in an LML CP3 Conversion (tuning may be required). It's a brand new pump, so no core is needed.
