You can't just lift a truck and not pay attention to driveline angles.
They have a preferred max operating angle before the U joints begin to get into improper actions and vibration.
It also aggravates the slip joint movement.
Should the axle housing dip downward under heavey braking, the front slip joint can come out to far.
You most likely need to put wedges under the springs to angle the pinion flange upward.
I'm sure lots of people have lifted and think they have gotten away with it; but it's not correct to do so without rear housing angle corrections.
Go to a shop that does this and get the right info.

that is a good way to do it.... I have shims in mine, but I lowered mine 2"s in the back... also I beleive I've seen a spacer that goes between the drive-shaft and the rear-end to make up for the loss of length.... Check fab tech's website, I think they're the one's that make it.
