Because then I could hit a switch and it will lift 4" automatically. You can still have all the handling of having a stock height VX but when you go offroad, 4 more inches instantly. It will actually be able to jump too, so I'm told. So if somethings too big to drive over I can just hop it I was planning on lifting it before I even owned it, and this seems to be the ideal way of doing it without loosing handling on the road.
