I've cut out the rockers from my truck and don't need them anymore. I won them a couple years ago here on CK5 from Blazen Offroad. Here is a link to the sliders on their site: https://blazenoffroad.com/displayProductDocument.hg?productId=4&categoryId=5 And here's the writeup I did on the install: http://coloradok5.com/forums/showthread.php?t=165951&highlight=blazen They are .188" thick 2"x3" square tubing. This is the shorter style, check out the thread here on CK5 for pictures of how they look. They're really stout, I have hit them very hard on many occassions and they've never dented. The bad news? They're pretty dirty and have part of my truck still attached to them. The good news? I only want $40 for them since that's what I paid in shipping. The steel alone is worth quite a bit more than that.
