Engineered specifically for high-horsepower competition and custom-tuned 2001 through 2010 Chevrolet Silverado and GMC Sierra 2500HD/3500 trucks powered by the 6.6L Duramax V8 turbo diesel engine (LB7, LLY, LBZ, and LMM platforms), the Dynomite Diesel Brand-New 12mm Stroker CP3 Pump (Part # NCP3-33212) provides massive fuel volume to support over 1,000 RWHP with proper supporting engine modifications.

Built entirely from new components without relying on remanufactured cores, this high-performance pump sustains full fuel delivery up to 6,000 RPM. Outfitted with an unmodified original equipment fuel control actuator for superior tuning precision, this outright performance unit requires no core deposit or core return.

Key Features & Benefits

• Supports Over 1,000 RWHP: Engineered with 12mm stroker plungers to deliver extreme fuel volume for high-output competition builds.
• Full Delivery to 6,000 RPM: Eliminates high-RPM fuel drop-off to sustain stable common rail pressure under aggressive racing conditions.
• 100% Brand-New Construction: Manufactured entirely with new parts, eliminating the wear and structural fatigue of rebuilt cores.
• Unmodified OEM FCA: Features an authentic factory fuel control actuator to optimize electronic tunability and idle stability.
• Zero Core Charge: Outright high-performance pump requiring no core deposit or core return shipping.

Vehicle Fitment & Technical Installation Notes

• 2001–2004 GM 2500HD / 3500 Duramax 6.6L (LB7 – requires custom tuning and FPR/FCA table rescaling)
• 2004.5–2005 GM 2500HD / 3500 Duramax 6.6L (LLY – requires custom tuning and FPR/FCA table rescaling)
• 2006–2007 GM 2500HD / 3500 Duramax 6.6L (LBZ Classic)
• 2007.5–2010 GM 2500HD / 3500 Duramax 6.6L (LMM)
• Installation Tip: Due to the extreme volumetric output of the 12mm plungers, DDP recommends pairing this pump with a high-capacity lift pump system (200 GPH or larger) regulated to 8–12 psi. Custom ECM tuning with rescaled LBZ fuel pressure regulator tables is required for 2001–2005 LB7 and LLY applications.
