I don't think anyone makes a "true" rock slider for the raptor. What the off-road community typically thinks of a rock slider as being able to carry the weight of the vehicle (or at least half weight) on the slider. And also to be able to use it as a jacking point of needed.
What I was referring to was this extra mounting point would be something to utilize if someone wanted to jack the tuck up with the slider. It spreads the weight out over the points instead of two.
Rockslide Engineering claims to have a true rock slider for the raptor, but I've yet to see photos of it in action other than their photos on the z.
