What's the price differences between add a leaf, mini spring Pack & X Codes? 2nd question I'd have are spring rates on the mini spring pack and Add a Leafs.
Personally, I'm going for quality of ride & towability. Ride height is last on my list of importance, but obviously they all go hand in hand.
A buddy of mine added a leaf on his F350 to raise the front an inch & it increased stiffness more than I'd like. These new trucks can haul great loads without riding like lumberwagons IMO.
MotionMan did the mini spring pack on his X. I should hook up with him while I'm in Mich to test the difference in ride & height.
