In my case, they don't properly center the filament spool, nor do they prevent the spool from rubbing against the left or right side of the AMS housing. Unfortunately, the guidance aids from the original Hydra system are no longer available on the Hydra Pro.With my slightly modified version, the spools run in the center and can no longer rub against the sides of the AMS. Now, there is always a 2mm distance on the left side, allowing the use of spools up to a width of 75mm. Many common 800g-1kg filament spools, such as Prusament, eSUN, Bambu, M4P, Extrudr, should fit.
