You'll probably have issues with your CV joints. You'd be better off doing a combination suspension lift, plus a 'body lift' to the front and rear drivetrain assemblies. As I understand it, they sit on their own subframe which can be lifted like you would a body lift. Not sure if you could use standard body lift type pucks or if you would have to fabricate something special for the gen III IFS subframe setup.
