My main dilemma is to get the +2 or the +3 deavers. I m running the eibach springs in the front and truck sits just a slight "bulldog" Are the +3 springs stiffer to make up the added 1" or is there just more leafs in the pack to make that up. I don't want a stiff spring. But a do often tow sxs. And I already have the SVC bumps stops.
