    Seal the combustion chamber and keep oil consumption in check on your next rebuild with the MAHLE Engine Piston Ring Set 40564CP030. Piston rings ride in the piston grooves to seal combustion pressure against the cylinder wall, control the oil film, and transfer heat from the piston into the bore — so a fresh set is a core part of any rering or overhaul. It is a direct-fit replacement for many vehicles, including the 1975-1986 Ford F-150 [V8-5.0L] and the 1964-1968 Ford Mustang [V8-4.7L]. See the "Vehicles it fits" section for the full list.

    • Bore fitment: sized for a 4.030 in bore.
    • Plasma-Moly face coating: applied to the ring faces.
    • Stainless steel oil ring assembly: handles oil control at the lower groove.
    • Premium grade, made in the United States: MAHLE rings are engineered to OE requirements to reduce friction and ring mass, help minimize oil consumption, and support longer service life.
