2004.5-2005 LLY Duramax Exergy 10mm Stroker CP3 Pump (LBZ Based)

Has your factory pump hit its limit, and you still need more pump capacity? Do you want the capability of more power without the worry of a multi-pump controller failing, a custom length belt breaking or a second pump to worry about? For applications up to 800+HP our 10mm Stroker CP3 pumps are the best option to take your build to the next level while incorporating all the increased reliability features of our Sportsman pump.

Pioneering a reliable modified CP3 pump did not come easy. Thousands of hours of research and development have gone into making our pumps what they are today. We found the limits on a durability test bench, not on customers vehicles. After the initial R&D was complete, each series of pump was subject to one final test in which we ran the pump at 4500 rpms and a pressure that far exceeded what the pumps will see in the field for 40 hours. A final inspection was done after this test to ensure no parts had significant wear. In production, each and every pump is tested throughout the entire operating range of the pump up to 4500 rpm and 29,000 psi to ensure 100% proper function before being installed into a vehicle.

Our 10mm Stroker pumps have been verified by third party testing to have a "Reasonable Bases" of being compliant with Federal Emission requirements.

Let Exergy give you peace of mind with your fuel system purchase!

Note: The Sportsman CP3 pumps intended for LLY engines are an LBZ based pump with an LLY fuel pressure regulator for ease of tuning. Please note, these should only be used on LLY applications.
