When you load your truck and the weight engages the entire lower spring pack(bottom leaf) and the overload leafs, the spring rate is much greater and there's a lot less side to side body roll.
If you load the truck down then pump the airbags back up to get it back level or close to unloaded height, you're not using all the springs. Air bags will hold the load up but for a high CoG load like a TC, the nature of the air bags is they'll have some flex in them.
If you achieve the same ride height, any weight not being carried by the springs is being carried by the airbags. The airbags likely have a higher spring rate than the overloads, and certainly more progressive. Like many things, the devil is the details. My truck has less body roll with full air suspension than it did on the springs.
But an antiroll bar is really the tool to solve body roll.
OP is not talking about air ride suspension though.
Add on airbags, if not using your overload springs (too much air) are like bouncy balls compared to air ride.
