That's my sister you pervs are having inappropriate thoughts about.
Pretty certain they are the rock rails. As a Limited it should have body coloured or black (can't remember on mine) plastic trim and it hugs the sill and does not stand out like that. It would also have the moulded front mud flaps normally. These don't fit with the rock rails and the rock rails do stick out like the pic and that is the colour of the rock rails. I put them on my Limited.
I could be wrong though but it will be pretty obvious to Shane if you have a good look underneath or hit them with something or a magnet.
