Question about keeping the rear end centered

[64stpside]

I have air shocks on my 64. I need them if I need to put a heavy load in the truck as the tires would contact the wheel wells under load.
My understanding is that with a track bar rearend you'll get some left to rt movement that's in relation to the truck height and the up and down movement of the truck while driving. The truck is on stk rear springs, stk suspension.
I see folks putting adjustable track bars on their trucks that are lowered.

Would I benefit from a adjustable track bar if im only raising the rear height when using the air shocks?

What is the range of movement that's acceptable. Right now I have my rear up a little and the passenger rear is sticking out at least an inch further than the drivers side.

If you're using air shocks to get the back up to "unloaded" height when loaded, you really don't need to change anything - it's going to be where it's supposed to be.

Plus, these trucks have been loaded/unloaded just fine for 50 years. It will probably be ok.

Look to add a set of the factory leaf overload springs. I have them on my 65, work like a charm when I really load it up.
