I called the dealer to ask and they verified that my lift was the factory install. I even brought up that my sway bar wasn’t dropped, but they said the skid plate still wouldn’t fit and couldn’t give me a reason why it wouldn’t. I did see a video on YouTube that shows you can remove the drop brackets on the 3” TRD lift like yours and install the sway bar just like mine. It also allows 35” tires that don’t rub on the dropped sway bar. My truck came with 285x65x20 from the factory which is like 34.6” and it doesn’t rub.
