2007.5-2010 LMM Duramax Exergy 12mm Stroker CP3 Pump (LBZ Based)

Looking for a single CP3 pump that will support up 1000+HP and drive like stock? Do you want the capability of more power without the worry of a pump controller failing, a custom belt breaking, mount cracking, or even a second pump to worry about? Keep your engine bay looking clean with a single stroker pump. Our 12mm Stroker CP3 pumps are the best option to take your build past the 1000HP mark.

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 12mm 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!
