I just discovered that my newly installed lift is not enough to allow much flex with 33x12.5x15 BFG MTs on 15x10 Eagle 589s. I have Tuff-Country's 2" EZ-Ride springs in front and 3" EZ-Ride springs in the rear. (It sits almost level this way - still slightly high in the front). So I am now in the market for a 4" lift. It seems like I could use my 3" rear springs and add 2" blocks or buy 4" springs all around. If I buy 4" springs all around, it seems like it would probably still need blocks in the rear to even it out. What would be the best way to go? Does anyone have any recommendations for spring combinations that would not require blocks to level out the truck?
