Screamin Diesel Performance

This kit allows you to switch from the CP4 injection pump that come from the factory on the 2011-2016 LML Duramax trucks, to an earlier model higher volume CP3 injection pump. Failure of the CP4 pump almost always results in damaged injectors and a very costly repair bill. Converting to a CP3 injection pump will not only add to your reliability, but you will also have more flow potential. EFI Live tuning is recommended with the CP3 conversion. Add an Exergy injection pump of your choice to make the kit complete!

This is an upgrade to the factory upper coolant hose going to the radiator. We make ours out of 304 Stainless Steel so you can be worry free of rust and deforming as you would get from either steel or aluminum. We can add 1/8"NPT bungs as necessary so that you can monitor temp or pressure with an auxiliary gauge.

This kit features a new drivers side IC pipe with billet dual seal clamp kit, 4" intake, high flow pedestal, 3" downpipe and more. It does not include a Y-bridge or coolant tank as some pictures show, these can be added for an extra cost.
