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. 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 requires modifications to the intercoolers pipes and you cannot run the airbox. Not practical for a DIYer but a shop can manage to make this 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

Full vband downpipe with heat wrap

Y bridge with cold side intercooler piping

All boots and clamps needed

Oil feed and return oil 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.
