I've been running the Yukon eliminator kit for about 5-6 years now, and have never had a problem. Granted, I don't try to break my junk, and if it looks like it may damage something, I'll back out and take a different line. I'm running 35's and ARB's F/R. I've seen people break stock, marfield and longs, but it's usually because of how they're driving. I have no experience with "dirty30's", so can't comment.
