Bud,
Tell us exactly what you have and you will receive a plethora of answers specific to your rig. General consensus is to get there by degrees installing one upgrade at a time until you reach equilibrium. For AK, (of which there my be 50 domestic units on here that have done the road), you want a little sturdier and stiffer attitude from your suspension and anti-sway upgrades. Personally, I would make airbags the last resort and make mechanical spring upgrades first resort.
Sounds like you want to skip the "suspension adventure" part of preparation and go right to the final working product.
Each brand of truck has a different molecular makup with some susp. upgrades working much better on X truck than they do on Y truck.
I see it my crystal ball: "All will be revealed". Just watch how the died-in-the-wool GM owners start buzzing around your camp. Only listen to them.
regards, as always, jefe
