2017-2019 Duramax L5P S400 Single Turbo Installation Kit

2017-2019 Duramax L5P S400 Single Turbo Installation Kit

We have brand new S400 single turbo kits in stock and available for immediate shipment! If this listing is visible, that means kits are still available. 


Please read this full description as it is filled with a ton of information and details!


Fits all 2017-2019 Duramax L5P 6.6L Diesel Pickup! Will we have a kit for the 2020-2023 trucks? Unfortunately we won't. These 17-19 kits can be modified to work on the 2020+ L5P but it does require custom fabrication to the driver intercoolers pipe and you cannot run the airbox. You will also need to repin the VGT dummy plug. Not practical for a DIY guy but a shop can manage to make these changes.


Here is our suggestion for turbo options,


S467 .90   Stock fuel or smaller fuel setup

S472 .90   60% - 100% Injectors and 10-12mm CP3


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 but can be added in the drop down options! 


For the installation kit here's what is included,


S400 5" Intake with dry filter and outerwear cover

T4 twisted pedestal with hardware

vband hot side intercooler pipe

vband downpipe with heat wrap

Y bridge with cold side intercooler piping

All boots and clamps needed

Oil feed and return lines

Any hardware needed to installation


If you do select the optional turbo in this listing, please note the compressor housing will be raw. It is not powder coated. If you wanted to coat the turbo to match the install kit, purchase this S400 turbo option found HERE


If you do not have these items below, we suggest the following to accomodate the install or may be needed to make it a complete kit. Some of these items are asked in the drop down options, but if you want to look at them individually, clicking VIEW HERE will take you to the item by itself on our website.

Something to note, this kit is a total of three very large packages for the installation kit by itself. If adding a turbo or heat blank, could make a total of 5 packages.




Q: Can I order this kit raw? 

A: No, these kits are pre packaged and all boxed up with the powder coated colors selected in the drop down menu. Under no circumstances are we able to ship a raw kit that is not powder coated.


Q: I am looking to piece together an S400 kit and don't need everything you are offering in this listing. Do you sell the individual components?

A: No, we only sell these in a complete kit. No exceptions.


Q: What colors do you currently have in stock?

A: The colors listed in the 'Powder Coat Color' drop down menu is what we physically have on hand, ready to ship. This is always updated and real time inventory with what we currently have. We do not list colors that we do not have readily available.


Q: I often times see listings on the internet that are old and outdated. Do you actually have these kits?

A: Yes, these kits are on hand and ready to ship! Hard to believe, I know. This listing is constantly updated and we do not sell items we do not have in stock unless it is stated clearly in the listing.


Q: How long does shipping take?

A: We ship most orders same business day as we receive them (Monday through Friday). This also depends what time during the day we receive the order. If it does not ship the same day, you will see tracking the following business day. All kits are located here in Pennsylvania so figure 1-3 days for east coast to mid west. 3-5 days for central to west coast. We cannot ship these to California.
