Telescoping half-shafts? Not on a snap-ring application. I don’t see a problem with this on bolt-in half-shafts (like 1500-2500 GM trucks). At some point the friction of the telescoping splines will overcome the holding power of the snap-ring. This will allow the inner cv to pull out of the housing and...PUKE.

BTW...this can happen with stock H3 shafts.

It's already a thing being done from GM. New Colorado is snap ring style and these are available from GM for snapping style.

They look awful similar. Would need to get ahold of a stock one at least to compare to the H3 arm.
