Difference in suspensions?

[Seth_5.7]

Probably a dumb question but is there a difference between the rear suspension of a 2wd and a 4wd? Because I'm looking at getting some rear lowering coils and they say that they are for a 2wd and wont fit a 4wd of the same year model.
These are the springs I'm looking at: https://www.americantrucks.com/max-trac-3-rear-lowering-springs-0918-2wd-ram-1500-w-o-air-ride.html

They're the same rear suspension's ,if it fits a 2wd it fits a 4X4.
