Detailed Description

This Sealed Power piston ring set is built around the specifications needed for select Ford gasoline engines using a 102.00 mm bore and standard ring sizing. The steel top ring with moly face helps maintain cylinder sealing under load, while the ductile iron second ring with phosphate coating supports stable ring operation and consistent oil scraping. The 1.50 mm top and second ring widths, along with the 2.50 mm oil ring width, match the listed groove dimensions for the application. This part number E-1004K also cross-references 2M4520 and AU7Z6148G for the same application.
