Drive Shaft Spacer?

so....i was watching "Trucks" on Spike TV, and they did a 3 1/2" lift on a Chevy Avalanche. Apparently, the truck has IFS like our KJs. They installed much taller springs and shocks up front, AND, they removed both half-shafts and added a spacer at the diff ends which looked exactly like a Spidertrax type wheel spacer. They said it was to prevent the shafts from pulling apart from the added height/length requirement. For all you "driveway engineers" out there, would that sort of a setup help out CV joint angle problem at all? I cant visualize it helping, but im posing the question for general knowledge.

I watched that also(love the older trucks) but that setup just wont work with out kj. The way chevy had the CV's setup was kinda neat. There was a flange coming out of the diff and the cv bolted to that flange where our cv's go into the diff.

Idk why the cv would pull apart with a mild lift like that. They lowered the lower control arm with a cradle drop(just lowered the lower control arm) but left everything else the same. Maybe the cradle drop pushed the bottom of the knuckle out to help with alignment which would over extend the cv?

Either way, thats never been a problem with a 3in(franken lift) lift on the liberty so we dont need it.
