Long and short eyelet same overall shock length. Short eyelet lowers the spring vs long.

I don't think it makes much difference in the end.
EDIT: Confirmed. All the eyelets do is move the relative position of the spring and shock collar on the shock body to maintain same ride height. The short eyelet allows more compression at the extreme. The only difference I can see.
