I gained 3" when I went from a 2" spacer to a 6" Pro Comp. Its just a matter of opinion whether you think 3" is "huge" or not. My wife is not that impressed by 3" anymore.

Also, for comparison. I had a 2010 Pro -4X, 34.5" tires, PRG 2" leveling kit first. Then all I changed was the lift, and left everything else the same.

from left to right: 2" leveling kit, 4" performance, and 6" lift to give you an idea.

pay no attention to the model.

From the pics, I think it's a pretty noticeable difference.
