Yeah it's not on the window sticker and here is a photo of the shocks. I have a mess of options but that isn't listed. It's just weird that the VIN says it does. These forms have given me lots to consider. I think I will start making some changes in 18k miles when the bumper to bumper runs out. Also found a guy selling the black factory 20s from an f150 with almost new tires. So might go that route also. Thanks everyone.
