Starting in 2019, the latest Cummins 6.7 platform switched over from the trusted and true CP3 pump that had since been ran on the Common Rails since 2003 to change over to the infamous Bosch CP4.2 pump. If you have any friends with a newer Duramax or Powerstroke, you will know the piss poor performance and reliability these CP4.2 style pumps are known for. When the CP4.2 fails, it allows very fine metal debris to be sent all throughout the fuel system contaminating the injectors, rails, lines, and all supply/return lines in the system to include the fuel tank. As a result, many of these precision components will require replacement that can be very costly. We have heard quite a few stories from companies not covering this under the factory warranty, thus passing along the cost to you! Making the switch from the CP4.2 for a CP3 is one of the best preventive maintenance items you can do for a 2019+ Cummins! Available in a multitude of performance flow options, this is your solution to taking care of that CP4 and upgrading to the ultimate CP3 reliability.

High Speed Pump? What is with that?
One of the improvements of this new generation of 6.7 is a front cover that over-drives the pump at a 1.5 to 1 ratio. To take advantage of this feature, S&S is offering kits with a high-speed optimized competition pumps. As a result, max RPM becomes an important consideration when choosing a pump for your truck.
