I followed PhoRunners videos on doing cheap bumpstops, and it works perfect. My rubbing in the front has pretty much disappeared, since it only rubbed bad while simultaneously turning and dropping off a ledge. The comments he makes about having the correct bolt is very important, as ACE and Wilco that carry the large bolt sets do not have the right socket head cap bolt to secure these. I ended up grinding down a hex bolt of the right thread pitch to fit a 12mm, which I was able to fit inside the front bumpstop. Normally the correct thread pitch is matched with a 14mm bolt, and the 14mm socket is too wide for the bumpstop. I got two sets of chevy bumpstops from the GMC model he lists in the video, and everything in the rear bolts up perfect. I haven't flexed out in the rear yet, but the size is really comparable to durobumps on paper, and I was having a lot of rubbing issues in the rear when fully flexed.
