Product Description
Feed big power the right way. The INDUSTRIAL INJECTION 23D402 Dual CP3 Kit adds a second high-pressure CP3 to your 2007.5–2018 6.7L Cummins so rail pressure stays rock-steady under heavy load and high RPM. This version includes a CP3 pump with all the brackets, belt drive, lines, and hardware for a clean, OE-style install.
Fitment
- 2007.5–2012 RAM 2500/3500 6.7L Cummins (6-speed manual, 68RFE, Aisin)
- 2013–2018 RAM 2500/3500 6.7L Cummins (68RFE/Aisin)
What’s Included
- (1) High-pressure CP3 pump (included)
- Upper pump bracket, pulleys, and drive belt
- High-pressure and return lines, fittings, hardware
- Installation components specific to 6.7L Cummins (’07.5–’18)
Why Dual CP3?
- Stable rail pressure under heavy fueling and boost
- Lower EGTs from improved atomization/complete burn
- Headroom for big injectors & turbo(s) without starving the rail
Recommended CPP Parts (Internal Links)
- ARP 247-4202 Head Stud Kit (1998.5–2024 Cummins)

Helpful Notes
- Lift pump recommended. A quality low-pressure supply is critical for CP3 longevity and pressure stability.
- ’13–’18 trucks may require/benefit from a dual-CP3 controller harness depending on ECU strategy and pump combo (see “Dual CP3 Harnesses/Accessories”).
- Professional installation and verification of rail pressure targets is strongly advised for high-power builds.
FAQ
Does this kit include a CP3 pump?Yes—23D402 is the with-pump kit. If you already have a secondary pump, see the no-pump kit (23D401) linked above.
Is tuning required after installing dual CP3s?Most performance builds will require tuning to command proper rail pressure and fueling. Work with a tuner who understands dual-pump strategies on the 6.7L Cummins.
Will this work with stock injectors and turbo?Yes—dual CP3s improve pressure stability even on stock injectors/turbo, and provide headroom for future upgrades.
What other parts should I add?A quality lift pump, ARP head studs, and fresh filtration are common adds. See the Recommended CPP Parts section above.
