Is tuning required with this SuperSport CP3 conversion?
The SuperSport CP3 is a high-speed, competition-optimized pump that leverages the 1.5× overdrive on 2019–2020 trucks. While S&S also offers a No-Tune CP3 conversion, the RAM-CP3-SS is intended for competition use; calibrations may be required for your race setup. Consult your builder/tuner for fueling and RPM strategy.
Why convert from the factory CP4.2?
The CP4.2 is known for premature failures that can contaminate the entire high-pressure fuel system with metal debris. The S&S CP3-based conversion is a durability-focused upgrade with proven reliability at high pressure and high RPM in severe conditions.
Will this kit fit Cab & Chassis models?
Primary fitment targets 2019–2020 RAM 2500/3500 pickups. For C&C applications, verify accessory and line routing differences before ordering.
What are the pump RPM considerations?
The 2019+ front cover overdrives the CP3 ~1.5× engine RPM. High-speed pumps have specific RPM limits; select the correct pump for your build and intended RPM ceiling.
Is this product emissions legal?
The RAM-CP3-SS is designated competition use only. If you need a street-legal solution, S&S offers a CARB-compliant No-Tune CP3 Conversion for 2019–2020 RAM (EO D-756-5).
