The ring package combines a grey iron top ring, grey iron second ring, and a steel rail\/stainless expander oil ring arrangement to support cylinder sealing and oil control. With phosphate-treated compression rings and a chrome-treated oil ring rail, this piston ring set is suited to rebuild work where consistent ring seating and wear resistance matter. It is listed for a wide range of Ford Mustang, Ford Falcon, and Mercury Comet applications, along with other classic Ford and Mercury models from the 1950s and 1960s.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestoring compression in worn cylinders\u003c\/li\u003e\n\u003cli\u003eReducing oil consumption from ring wear\u003c\/li\u003e\n\u003cli\u003eAddressing blow-by caused by poor ring sealing\u003c\/li\u003e\n\u003cli\u003eSupporting engine rebuilds on classic Ford and Mercury V8 platforms\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify bore size, groove dimensions, and ring end gap before installation.
