19HP Platinum Piston Rings

I purchased Stens 500-074/STD piston rings to replace the original B&S rings.  The oil ring setup is different with the Stens rings - the B&S oil ring has a "polygonal expander" installed behind it (see photo).  Do I leave this B&S polygonal expander in or do I take it out when installing the Stens rings?
