I have all the factory skids & also the belly plate from 4x. So far they work great & no issues. I do plan on replacing the muffler with a flowmaster & that will take care of that area because of how thick they are. I do agree with what Stroker said, they are there to protect if needed but don't rely on them and do the crazy stuff like (Stab & steer type of wheeling) you will break everything like that, so I enjoy myself on the trails but also try to watch my lines the best I can.
