I have no idea how much the back is lifted, i'd say 5 or 6", the front is 4.5 or 5". I'm not sure.
I did have to cut back the fender 3" or 4", that wasn't the hard part. I had to hammber back the piece of metal inside the fender and cut a lot of the plastic inner fenderwell.
I still rub if my front tire stuffs in the front, but that's only on the inner plastic fenderwell(I think).
After I get a new front driveshaft(my old one is broken), i'm probably going to regear, the 5.0L helps push it along but it's not enough, plus the lack of 4low is bad enough.
My only complaint is that these tires were a pain to get balanced. 4wheelparts sent them to me balanced and I put them on, from 35-60mph the steering wheel would shake. There were a lot of weights on 2 of the tires, probably over 10 so I put the ones with the least amount of weights in the front. I went to a local tire place here to get them rebalanced and they dynamically balanced the front ones to get rid of the shimmy. It took a lot of weights, imagine that first picture with three LONG weights on the outside of the front wheels, that's how it looks now.
I do like these tires though, after getting them balanced, they ride well, aren't loud(can't hear them over the lack of mufflers... which also need to be put back on). Once I get a front driveshaft back in, i'll put the tires to the test.
