S&S DIESEL CP3-DMX-10-HS 10MM CP3 HIGH SPEED (NEW) — LBZ-BASED

Built for high RPM efficiency. The S&S Diesel Motorsport CP3-DMX-10-HS is a brand-new, LBZ-based Bosch CP3NH high-pressure pump that’s internally optimized for high-speed output. It delivers 10mm (1,325 mm³/rev) displacement with data-backed performance for 2001–2010 GM Duramax 6.6L LB7/LLY/LBZ applications.

• Brand-new LBZ-based Bosch CP3NH core (no reman components)
• High-speed internal calibration for strong output at elevated RPM
• Each unit is flow-tested and supplied with a data sheet

Fitment

• 2001–2004 GM Duramax 6.6L LB7
• 2004.5–2005 GM Duramax 6.6L LLY
• 2006–2007 GM Duramax 6.6L LBZ
• Also used in dual-CP3 and swap configurations for 2001–2010 platforms where LBZ-based CP3s are specified

Note: Early LB7/LLY trucks may require tuning when moving to certain high-speed CP3 calibrations. Verify your calibration needs before purchase.

FAQ

It’s a brand-new LBZ-based Bosch CP3NH unit that S&S modifies and flow-tests. No reman components.

For best performance and to maintain rail stability at higher RPM, a quality lift pump is strongly recommended. See the AirDog and FASS options linked above.

Many early 2001–2005 LB7/LLY trucks do require tuning to fully integrate a high-speed CP3. Consult your tuner and build goals before installation.

High-speed S&S CP3s are engineered to sustain strong L/h flow at elevated pump speeds—ideal for builds that routinely spin beyond ~4,500 RPM.

Inspect/refresh seals on the primer, ensure clean filtration, and consider upgraded supply plumbing. See our seal kit and filter delete linked above.
