These are in fact the wheels that came on the 2012-2013 JGC Overland Summit, as the part number on Just For Jeeps matches up with the one given on WK2 Jeeps (link below, style 11).
I just purchased a 2017 GC Overland Billet Silver with the tech gray 20" wheels. Those wheels are okay but I really liked the 20" wheels that came with the 2014 GC Limited that I traded in.
I priced out the 2014 wheel at the Jeep dealer and they want $565 per wheel. Now I need to find a place where I can buy those mopar wheels at a lower cost.
Please post a link if anyone knows where I can get them for a lower price.
