In my humble opinion since I have actually rockcrawled on a "professional" level, I have ripped the factory crossmember off of the frame and snapped off the cast in mounting bosses on the bottom of the low range unit of a transfer case. I personally feel that a thick ass piece of plate steel is better than leaving your cast aluminum transfer case with it's ass hanging out in the breeze. I like the way the FROR bracket bolts to the output shaft housing, it looks strong as hell! I just didn't like the look of the skid plate part of it as it appeared to look no different than the factory toyota type.
