Please read this full description as it is filled with a ton of information and details! At the bottom you will find commonly asked questions as well.
 
Fits all 2017-2019 Duramax L5P 6.6L Diesel 2500/3500HD Pickup truck!
 
Will we have a kit for the 2020-2023 L5P Pickup trucks? Unfortunately we won't. These 2017-2019 kits can be modified to work on the 2020+ L5P however it does require custom fabrication to the driver side intercooler pipe to clear the ECM. If you do plan to go this route, it's best to buy the matching driver side pipe (if you don't have one already) HERE and use this to connect to the S400 driverside intercooler pipe. You cannot run the airbox provided in this kit as it will not fit and line up with the ram air from the hood scoop. You will also need to repin the provided VGT dummy plug. Not practical for a DIY guy but an install shop can manage to make these changes. We do offer a drop in series S300 kit which works great on the 2020+ trucks too and does not require the modifications to the hot side. John C Garage S300 Kit
 
Here is our suggestion for turbo choices,
S463.5 (AKA S464) (63.5mm/83mm/.90 A/R T4) Stock fuel system 650-700HP
S467 (67.7mm/83mm/.90 A/R T4) Stock fueling or smaller fuel setup 800HP
S472  (72mm/83mm/.90 A/R T4) 50% - 150% Injectors and 10-14mm CP3 850+HP
 
The colors listed are the only options we have available and we do not have the ability to get any other colors. If you want a different color, grab a kit and get it repowder coated. We have done this several times and any powder coat shop can easily do that.
 
There will be no turbo included with the base installation kit (first photo) but can be added in the drop down options!
