S&S Diesel Motorsport SuperSport CP3 Pump – CP3-DMX-SS Fits: 2001–2010 GM 6.6L Duramax (LB7 / LLY / LBZ / LMM)

Upgrade your Duramax with the S&S Diesel Motorsport SuperSport CP3 (part # CP3-DMX-SS). This is a brand-new, LBZ-based Bosch CP3 that S&S modifies for higher sustained fuel output above 3,500 RPM—where stock CP3 pumps typically begin to fall off around 3,000 RPM.

Built from a new OE-style housing (not a reman), the SuperSport is an excellent semi-stock performance upgrade for everyday driving, towing, and moderate power goals. It delivers improved high-RPM fueling and efficiency while maintaining the proven reliability of the CP3 design.

Key Features

• Brand-new LBZ-based Bosch CP3 (no core charge)
• Internally modified for higher output and sustained delivery above 3,500 RPM
• Precision-built to S&S Diesel Motorsport standards
• Includes calibration data sheet for proper ECM setup
• Direct fit for 2001–2010 Silverado/Sierra 2500HD & 3500HD 6.6L Duramax
• 2-year manufacturer warranty

Important Notes

• Custom tuning is required on 2001–2005 LB7 and LLY engines.
• On LB7 applications, the regulator connectors may need minor modification for proper fit.

Ideal for stock-to-mildly modified trucks looking for better fueling stability and power potential without jumping to a full stroker pump. Pair with a quality lift pump (150+ GPH recommended) for best results.
