Product Description
The BD DIESEL 1050651 R900 12mm Stroker CP3 Injection Pump is a high-flow performance CP3 pump engineered for 2001–2010 Chevy/GMC 6.6L Duramax diesel engines. Featuring a modified 12mm stroke camshaft and enhanced plunger design, this upgraded CP3 pump produces significantly more fuel flow—up to approximately 5.25 LPM compared to the stock ~3.05 LPM—making it capable of supporting increased power levels while maintaining proper rail pressure for efficient atomization and combustion.
Designed as a drop-in replacement for the stock CP3 injection pump, this R900 unit delivers consistent high-pressure fuel supply on demand without the need for additional pulleys, belts, or secondary pumps. Its upgraded shaft material and heat-treated components enhance durability, allowing for reliable performance under heavy load and high-power applications.
