they are actually JCR sliders. i was going around a rock and the slider went to the under side of the rock instead of the side or top. so as it was under the rock the jeep tilted the other way and there went the slider. stripped like 6 of the self tappers out. the others just pulled the unibody out so its not flat anymore. and the pinch seam is torn where the bolts pulled out. no error in installation. i have had them for years and beat them good. so i think ill be doing a 2x6 box rocker replacement and sell these off when i get around to it
and i only weigh 165 BTW
