I think those are called "load levelers". Usually used to help older leaf springs. You may find that the car squats too much without them. There are also helper springs that fit the same way with top and bottom clamps.

Y's guys rule!

Our 56 Ranch Wagon rear shocks have a coil over ("helper")  spring set-up (in addition to the leaf springs). All the aftermarket rear shocks I've seen are just the mono-tube design without the spring. I don't think these are OEM rear shocks, but I'm not sure. The bottom of the spring sits on a flange that appears to be part of the shock. Are there other aftermarket shocks available with the studs on both ends that include these springs or should I just replace them with a set of Gabriel's and be done with it?
Thanks,
