what is this hub kit

[styler]

I recently purchased a Bravo 1 fs and the kit on the right came with it.
The kit on the left is what I have been using with my Tempest +
Either kit works with the Bravo on my engine. Ive never seen that kind on the right . what is it? Im thinking I should be using the one on the left correct?

I think the one on the right is the new SSR hub kit. Should shift and idle smoother without any prop rattle, and is Merc's most recent hub. Can be difficult to remove.
