plannin on runnin 44's??

body lift doesn't affect column, well  you need to sometimes remove the keeper pin for the shaft to extend out but that's about it. Shifters are another story personally I wouldn't go above a 2" lift. I have a 2", 4" springs and shackles and easily ran 38's with tons o travel.

you'll have to modify drivelines for the lift and for the dual case fo sure. Why skyjacker springs?
