OK, so something is up. I have a list of parts to potentially upgrade on my SS. Of which, are the OEM FE4 suspension links. In example, the front, lower radius arm, the one you have pictured, for the left on a'17 SS 1LE is service part number 84051641. Take a look at this:

A few pictures look to have the more solid bushing, like the "ZL1 1LE" kit has, but the others have what you posted. Unless, according to the guys comments, the initial pictures are some "standard SS" ones he got a hold of?
