What I can tell you is that in addition to Shrockworks, PUREJEEP and ARB, I've installed and tested LoD rocker guards and thought they held up well. In fact, I ran them for a long time on two of my JK's before installing EVO. You should be able to see them in action on some of our older videos. That being said, you need to remember that unlike the TJ before which essentially had hockey pucks for body mounts, the JK has true body mounts as in, they're isolators and allow for a LOT more movement. They are in part what makes the JK ride nicer and with less road noise but the problem with this is that ANY frame mounted rocker guard can potentially make contact with the rocker panels as the tub physically moves up and down with big hits. The LoD does sit close enough to the panel that a really hard hit can cause it to make contact but not enough to do anything more than put small dent in it. Or, at least, that's what I had found but then, you'd have to judge for yourself just how hard I play. That's about as honestly as I can put it and with that said, I personally would still recommend the LoD sliders given what you're wanting.
