I think you will need frame spacers. This will solve the torsion bar issue but cause another one with the steering links. Frame spacers will also keep the drive shafts in their correct geometry as well. Guys get crazy lift on some of the 4x4's so it can be done (although not always in the ideal way). I'm not savvy with 4x4 lift but spacers seem the most logical way unless you are planning on doing some big rock climbing (then we need PICS or else!)
