Lowering my dually?
Does anyone know of an easy way to take 2" out of the bed height on my 2006 Ram dually? Would it create a domino effect to other suspension system changes?

It will change your drive line angle. If you are getting considerable squat from your load plus lowering axle height you may find u-joints failing under heavy load or joints binding during spring compression. Lowering the rear too much without adjusting the front may make the truck nose high when loaded - This will affect your steering and lighting.
By your logic, putting weight in the bed will change the driveline angle.
Removing the spring spacers and leaving the bumpstops in the same place does not change the range of the factory suspension. In other words, the "driveline angle" that is created by moving the spacers is the same as putting some weight in the bed and compressing the springs.
The driveline angle necessary to bind the u joints in these trucks is in excess of 30 degrees, perhaps even in excess of 35 degrees. The factory driveline angle is a single digit, probably in the range of 3-5 degrees with the rear suspension completely drooped. Also, moving the rear axle straight up and down by moving those spacers is unlikely to make even a measurable change in the driveline angle at rest.
Don't take my word for it, though. Download an angle finder app on your phone and you can see for yourself.
Where you got the idea that an inch change in ride height was going to cause driveshaft binding is beyond me. Whoever told you that was feeding you nonsense.
The current generations of trucks are way too tall and there are far greater consequences from not lowering them (bedrails getting hit by the trailer, ride height) than from lowering them.
