That's there not in case the pillowball gets stiff, but because a coil spring rotates as it compressses, it should have been fitted to the spring seat with some anti sieze to allow slight movement to keep everything quiet. There's no reason it shouldn't be plastic, metal ones can actually be worse, the spring diveders on the buggy are plastic and i've never managed to chew one up even covered in shit. It shouldn't happen unless the springs are loose on full droop.
