They’re just ridiculously elastic - so much so that the smaller end that fits on the CV shaft will open up enough to allow these things to slide completely over the hub (when you use the kit’s yellow mounting cone and lubricant) – then they instantly snap back to their original shape… ‘POP!’ - it’s on there.

You’ve just got to see it to believe it!
