If you own an F250 or another model, why would you use blocks (2", 4") instead of adding springs to the rear of your truck for the extra payload? i know price cant be a major issue, just seems that a spring would be more usefull. thinking about adding a spring instead of the 4" F350 block.
ps. what are good Add-a-Leafs? Super Lift, Rancho, etc?
