See, this 2" lift sounds more like me. The 6", although it looks friggin beast, serves no purpose for my situation I guess. I need my truck to handle snow and small rock, but not crazy boulder crawling business. I'm from northern Colorado and if I can have something that will ride over some small rocks comfortably then I'm good. I'm only on these tight little rocky trails that I use to get to my dispersed camping sites. 2" on 33's will look good too.
You're right that I never thought about flex. My current backspacing is at -22mm and that was chosen because 0 offset would not clear the outer tie rods. It was not chosen based on anything else, but that they fit.
So skyjacker is great for street. What brands would you recommend for my situation? Mountain roads, dirt trails peppered with lots of pointy rock, and snow snow snow. I call the truck Gunther because Gunther is a guy that rams into things for no reason, breaks 3 ribs doing it, and doesn't get to the doctor for about 3 weeks because he's too busy boozin' and neglecting his stepchildren.
As roundhouse said, I've been told a bunch of times that 33's will fit fine, but then the dude at the tire is telling me I may have to shave the fenders a bit. If its that close then maybe its not safe enough. I'm in your guys's hands.
