a lot of people have been talking about the 6" skyjacker leaf springs. I have a superlift and I was thinking about getting the lift springs so I would be able to get rid of the lift blocks. I went out and measured the blocks and they are about 5 3/4" tall total (stock block & superlift block). so by going with the new spring it will be about a 1/4" higher. I was told that I would have to crank my tbars to get it to sit like it does now is that true? they are not cranked right now. also my leafs look really flat. I have never really paid much attention to them what do you guys think? if they are bad how much "lift " do you think I my have lost?
