How much clearance do you have before hitting the bump stops on your lower arms?

As a small note, I ran across some aftermarket bump stops that are meant to assist the factory springs. They are tall multi-donut looking things. I recall generic, not specific to any Mopar models. I don't know if they are intended to touch in normal driving, or just when you hit a bigger bump. I would be worried about them squeaking if they always touch. I was looking for front shocks w/ helper springs for my C-body since new torsion bars are ~$400 for it.
