Description
S&S Diesel Motorsport builds this high-pressure pump for diesel engines making more power than a factory CP3 can feed. It starts as a brand-new Bosch CP3 that S&S modifies and tests in-house, so you get a fresh pump with no core to send back.
Pick this one when you've outgrown a stock or mild stroker pump and need steady rail pressure at high fuel rates. It suits competition trucks, sled pullers and high-horsepower street builds where the supporting mods are already done.
Why we like it
- Brand-new Bosch CP3 base pump, modified by S&S (not a remanufactured core unit)
- SuperSport build for higher output above roughly 3,500 pump RPM
- LBZ/LMM Duramax-based housing
- Emissions: not CARB exempt. For off-road or competition use only on pollution-controlled vehicles
What's in the box
One S&S Diesel Motorsport CP3 high-pressure pump. Fittings, lines and tuning are not included unless your build already has them.
Fitment
2001–2010 Chevy/GMC 2500HD/3500HD 6.6L Duramax LB7/LLY/LBZ/LMM. S&S Diesel Motorsport part number CP3-DMX-SS.
Install notes
Built for competition and high-horsepower builds. Most engines need tuning changes to control rail pressure with a larger pump. Professional installation recommended. LB7 and LLY engines may need different fittings or lines; call us to confirm before ordering.
California and CARB states: this part does not have a CARB exemption number, so it is for off-road or competition use only on pollution-controlled vehicles in those states. We do not ship it to California.
