Only MAHLE Original can claim to be the largest manufacturer of piston rings in the world today.
This stability leads to a tremendous foundation for research and development, which guarantees that MAHLE Original is the highest performing ring in both performance and light vehicle applications.
MAHLE Original piston rings lead the way in innovation and ring technology for the Aftermarket - after all, MAHLE is the largest manufacturer of piston rings in the world.
MAHLE Original rings are at the forefront of piston ring technology for light vehicles.
Extensive OE connections mean that MAHLE Original rings have the technological edge.
Things like the CP-20 oil ring, narrow compression rings, steel compression rings for gasoline engines, low-tension oil rings, and coated compression rings for diesels all came from the OE.
The MAHLE Original performance line proves time and again that it should be the ring of choice under every hood - regardless of the application.
Traditionally, grey cast iron or ductile iron was the material of choice for automotive applications - today, more and more engine builders prefer steel over iron.
Steel compression ring technology has been used in heavy-duty applications for over 30 years.
That know-how has become essential to the design and engineering of today's automotive engines.
Steel piston rings offer higher tensile strength, higher yield strength, greater fatigue life, and greater hardness while still offering a lower ring mass.
These factors lead to better stress resistance, reduced groove pound-out, longer service life, better conformability, superior oil economy, and improved blow-by control while still lowering friction.
