Just an update, I was able to scrape the skid over a hard high point locally (cement) to determine if any deflection occurred. It contacted at the rear portion under the diff case. No deflection of the skid at all, just a scrape and a little paint removal from the skid. Also, after even closer inspection, I discovered that there are eight total bolts attaching the skid to the case. I previously thought there were only six. There are the four that run up/down through the brackets near the pinion end, and four more along the rear of the diff, running fore/aft through the webbing along the bottom of the case. This is also the area where the entire skid butts against the bottom of the case to create hard mounting in order to not allow the skid to deflect or flex, which prevents it from cracking the flanges/webs on the case. I have been dealing with folks on DT that have been throwing me on the fire, thinking that the only attachment is via the four bolts and brackets near the pinion end, and how cast iron is not as strong as steel (granted). However, because it is hard mounted and butted against the case, the skid can't really move at all during a rock strike. That said, there is a chance that a direct, really hard, drop on the pinion end might cause deflection, but that has to be an extreme case where that part of the skid would be the only thing contacted during such a drop. That's got to be in the .001% chance range. Most all strikes in that area would be glancing blows during forward movement, and a drop will most likely hit the bottom of the skid near the case way before it would subsequently drop onto the pinion area. Even so, the brackets coming off the skid at the pinion area are gusseted, providing additional rigidity to combat any deformation there. Anyway, just wanted to post an update to help assuage any concerns out there. Really not enjoying the DT crowd....several just seem to crap on the idea without offering true suggestions to help. Only one guy went on to explain why he had concerns, and how it might be improved. That's cool, and that kind of constructive criticism is welcome. I tried to explain as best I could why the mounting points and design actually address his concerns and that the design is sound. I guess the photos don't really show everything needed, but the angles and light provided while underneath the truck don't allow much more without seeing with your own eyes. No...it would not survive an IED blast, but I still feel certain it will handle just about anything I'd encounter while wheeling. Then again, I don't jump my truck and I do believe in spotters. OK...rant complete.
