The Roush kit comes with a Supplemental Power Train warranty included for the 525fwhp
and then you need to buy the second warranty for the stage2 kit.
Both of these warranties are back up by Roush themselves. Not Ford!!!!!!
These are Supplemental Power Train Warranties!!! Since Ford's Power Train will be voided.
The Whipple Supplemental Power Train warranty comes from Cornerstone Warranties.
And does not come included you need to buy that at the time of install.
Again, this is a Supplemental Power Train Warranty!!! Since Ford's Power Train will be voided
If you have your SC installed by an authorized installer (either one)
then your whole Factory Warranty is not automatically voided, except the Power Train.
Again, Ford Motor Company Does Not warranty the power train on a Raptor with a Supercharger.
Nor does Ford back up any (and I mean any) of these Supplemental Power Train Warranties.
Everything else is cover by Ford.
It's up to the dealer to work with these supplemental warranties, if their even willing to do that.
This is the way it's been since day one and nothing has changed.
