My 2019 Roush Raptor was build by Roush same with 2017 Supercharged ... when you buy truck ready thats build by them or if Roush installs the parts themselves it comes automatically with warranty depending how much factory warranty you have. If lets say dealer installs the Roush Supercharger you have option to purchase 3/36,000 mile warranty of course if your truck still has factory warranty or you dont have to but it doesnt come included only 1 year on parts is included if you dont get warranty. I am not sure how it goes with PowerPack on Raptor when you purchase it from them I would suggest calling Roush. I always bought new Roush trucks with their packages already installed so it was always with warranty included.
