Product Description
Hit and hold rail pressure on tuned LBZ/LMM builds. The INDUSTRIAL INJECTION Double Dragon 120 CP3 (PN 0986437332DD) is a remanufactured, 12mm stroker pump that flows ~120% over stock for the 2006–2007 Duramax LBZ/LMM. Built from an OEM Bosch core and assembled with new Bosch internals and a new Fuel Control Actuator (FCA), this pump is calibrated in-house for smooth idle, reliable pressure, and headroom for larger injectors and higher pulse widths.
- 120% over stock flow with 12mm stroker shaft
- New Bosch FCA and new Bosch-spec internal components
- Calibrated to exceed OEM spec for consistency at high demand
- Ideal with a quality lift pump and clean fuel supply
Fitment
- Chevy/GMC 2500HD/3500HD 6.6L Duramax LBZ (2006–2007)
- Chevy/GMC 2500HD/3500HD 6.6L Duramax LMM (model-year 2007 “Classic” overlap; verify build date)
Note: If your 2007 truck is an LMM (2007.5+), confirm harness/line routing before ordering. For 2007.5–2010 LMM applications, contact us for the correct configuration.

FAQ
Do I need a lift pump with this CP3?
Highly recommended. A quality lift pump helps maintain inlet pressure, reduces aeration/cavitation, improves filter life, and supports rail pressure at higher pulse widths.
Will this support larger injectors and aggressive tuning?
Yes. The Double Dragon 120 flows ~120% over stock and is designed to maintain commanded pressure with larger injectors and high-demand tunes when fuel supply is adequate.
Is calibration performed after assembly?
Yes. Units are calibrated in-house to exceed OEM spec for smooth idle and consistent delivery across the RPM/load range.
What’s the core policy?
A refundable core charge applies at purchase. Return an acceptable core in a timely manner for credit according to CPP’s core return terms.
Is this pump emissions legal for on-road use?
Many performance CP3s are intended for competition/off-road use where required by law. Verify local regulations before purchasing.
