S&S CP3 Injection Pump for Cummins trucks.


High speed pumps have increased output at high RPMs. These are ideal for competition trucks which spin higher RPMs, or for all 2019+ Cummins trucks. All 2019+ 6.7 Cummins have the injection pump overdriven at a 1.5:1 ratio. Because of this, it is not recommended to run a non-high speed pump on 2019+ trucks.



Stock / Supersport - 600HP (Supersport has increased fueling beyond 3500rpm vs stock)

10mm Stroker - 800HP

12mm Stroker - 1000HP

14mm Stroker - 1200HP


High Speed Pump RPM Limits for 2019+ Trucks:

10mm High Speed – 8,000 pump RPM (this is 5,333 engine RPM for 2019+)
12mm High Speed – 7,000 pump RPM (this is 4,667 engine RPM for 2019+)
14mm High Speed – 6,000 pump RPM (this is 4,000 engine RPM for 2019+)



**On 5.9 trucks, these will require modification to the feed lines, unless you are running a lift pump with a new feed line to the CP3

**Only fits 2019-2020 Cummins 6.7 which have been converted to a CP3 or the factory CP-ISB injection pump. Direct fit for 2007.5-2018 and 2021-2022 6.7s.
