I know that I have been asking a lot of questions about suspension kits but I just want to do it right the first time. I already have a 2.5" Ready Lift Leveling Kit on my truck now. I don't have the rear blocks installed. I am running 35x12.50 on stock 20's. Is it worth the trouble to upgrade to a 4.5" kit or am I waisting my time with trying to find a kit? Do they make a difference? Does one look better than the other? What is your opinion? I am interested to hear.
