The Mahle OE chrome piston ring set applies OE-derived ring design to reduce friction and limit oil consumption while delivering longer service life in rebuilds. MAHLE focuses on advanced piston ring engineering. This chrome set fits Ford engines in the 359/361/389/391 family for model years 1974–1978, providing a direct-fit replacement where that engine grouping is maintained.
