You would not be able to use the struts off a Raptor with this lift. From my understanding, you can either use the factory Raptor struts as part of a complete Raptor swap with Raptor UCAs, LCAs, CVs, and tie rods or use them as a standalone for a 4" lift kit. They're not tall enough for a 6" lift on their own, and they're too tall to be used in conjunction with McGaughy's strut spacers.
