They say they stop the tire from coming up in your floor on a head on. I still have mine on the floor in the garage, but I have RS Sliders which will stop the tire movement back. Those frame horns are welded to the frame on a 2008 up.
The sliders are attached to the body, not the frame. I doubt they would serve the same function as the frame horn.
These type of modifications make me really nervous. Kinda like when I see hilift jacks on front bumpers or above the hood on a front bull bar. It's just a missile waiting to launch through the front windshield.
