The S&S Injection Pump (12mm Stroker Pump) is a high-performance fuel pump engineered for 2001-2015 GM Duramax engines. Built from brand-new Bosch LBZ-based pumps, these units are modified to meet the diverse fueling needs of engines producing between 500 and 1,400 horsepower in a single pump configuration.
S&S CP3 pumps go beyond simply increasing displacement. These pumps are internally modified to efficiently deliver fuel well beyond the peak RPM of most diesel engines, making them ideal for competition engines that require high-RPM fueling. While not necessary for all applications, these competition-grade pumps provide unmatched performance for those who demand the best.
Included with every S&S CP3 pump is a crucial data sheet that provides detailed information for proper calibration. For models from 2001 to 2005 (LB7 and LLY), custom tuning is required to ensure optimal performance.
