Unlock The True Fuel Potential Of Your LML Build

If you are pushing your 2011-2016 Silverado or Sierra 2500HD or 3500HD beyond stock power levels, the factory fuel system can quickly become the limiting factor. The Exergy E04-10506 10MM Stroker CP4 Pump is built for owners who want more fuel delivery without cutting corners on quality. This upgraded pump increases output over the stock unit, giving your LML Duramax the volume it needs to support higher horsepower tuning. Whether you are towing heavy with added power or building a street and strip truck, consistent fuel supply is critical to keeping performance smooth and reliable. Additionally, Exergy brings true OE level engineering into the high performance world, so you are not just getting more fuel, you are getting controlled and verified performance. That peace of mind matters when you have invested in injectors, tuning, and supporting mods. When you are ready to take your LML to the next level, this 10mm stroker pump is a serious step forward.

OE Level Testing And Validation For High Performance Common Rail Systems

Exergy approaches performance fuel system components with the same mindset used in original equipment development. Each 10mm stroker CP4 pump is tested from idle to full power using factory calibration points, along with additional points tailored for high performance applications. Furthermore, Exergy utilizes Bosch developed equipment designed specifically for common rail system development, allowing detailed analysis beyond basic fuel output. This advanced testing measures injection quantity, shot to shot consistency, and injection timing to ensure proper function across the operating range. That level of verification is not typical of standard diesel repair shops and provides added confidence in demanding builds. The pump is also well suited for trucks running custom tuning through EFI Live or stand alone ECU setups, where accurate fuel control is essential. When installed on a properly prepared 2011-2016 LML Duramax, this pump supports stronger fuel delivery while maintaining the precision modern common rail systems require.
