Alright so i have a 1999 expedition Eddie Bauer With an air ride suspension. Can you help me find the cheapest way to lift this, mainly for an everyday driver, not for much off road use. Just need to know what I have to do and what to buy. I was looking at the 3" body lift 2" torsion key 2" spacers or 3" torsion 3" spacers. What would I have to do to apply this with an air ride suspension? How do I convert from air ride? Thanks!
