Quite well, actually.
I was able to pivot around rocks with the kickout and drop down to slide over ledges that would have wrecked the body if I didn't have sliders.
At one point I had most of the truck's weight on the back end of the cat protection plate and it didn't bend or move it at all.
And I even remembered to get pictures...

Apparently, XMLs flex pretty good when you push the tire so hard against a rock that it lets all the air out of the bead...lol.
The sliders work nice. If I didn't have them...
