I don't know what to call them but they are posts that stick out under the fender to slide your sway bar links on when you disconnect. I got an Antirock and dont need them anymore and thought I would pass them on. Free + shipping (if you require it). One of them is a little beat up from trying to get it off but can be sanded smooth again.
I will post a better picture but it is the brown/purple post right above the Spring Tower:
