Only MAHLE Original can claim to be the largest manufacturer of piston rings in the world today.
This stability results in a tremendous research and development foundation, 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.
At the forefront of light vehicle piston ring technology, MAHLE Original rings benefit from extensive OE connections that provide a technological edge.
Innovations such as 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 originated from the OE.
The MAHLE Original performance line consistently proves to 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 engine builders prefer steel over iron.
Steel compression ring technology has been utilized in heavy-duty applications for over 30 years.
That expertise has become essential to the design and engineering of today's automotive engines.
