If the weather clears up tonight and I get home before dark I will post before and after pictures of my truck sitting on level ground to show how much it changed.
I actually installed my 4.5 inch Superlift to replace the 3.5 inch Pro Comp springs (rear blocks) that were on the truck when I purchased it. I don't like blocks, it seems like the cheap way out and it has a negative effect on axle wrap; however, now that I have quality rear springs installed and need a tiny bit more lift, I don't feel to bad about 1 inch blocks. The Alcan springs have the top axle wrap leaf so I am not too concerned about that being a problem.
