2011 Ram 2500 suspension question

I had on 01 2500 ram it had a rather tall block under the rear springs came stock like that. On my 17 3500 it has 3 or perhaps 4 of those plates. Those plates are in place of the old block. They are short enough at least on mine and are no longer than the blocks that was under my 01 they should not be keeping the springs from flexing. I doubt someone changed out the block for the plates. I know my 17 3500 does not squat near as much as my 01 2500 and actually had to raise my trailer a couple inches just to get the bed rail clearance required. On my 17 those plates are about 1/2 to 3/4 inch thick iirc and you may be able to take some out but I would not take them all out as they support the spring pack on the top of the axle. I know my 17 is not an 11 so it may be different.
