I never had any problems running the 7" and 35's on that TJ. The only time I broke anything was trying to pull things that I shouldn't have, and I ended up exploding the spider gears in the front axle (twice). I did some pretty insane wheeling with it, and flexed the hell out of that suspension with no issues. It is all about driving style, taking it easy on the skinny peddle when you need to, and knowing the limits of yourself and your equipment. My next project when I get home will be a mid-90's XJ, which will eventually get an 8" long arm lift and whatever trimming is required to get 35's under it. Eventually, when I can save nough I will swap the real leaf springs for coils, but that is further down the road. I am definitely interested in those MOPAR JK dana 44's that come with the 4.10's and electric locker, but again, that is further down the road.
