These Mahle Original piston ring sets are engineered to be easy to install. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. As temperatures, pressures, and rotational speeds continue to rise, piston rings are subjected to ever increasing loads. Concepts for lower wear and friction, better sealing, and greater break resistance are in demand. MAHLE is therefore continuously developing new coatings and ring design variants and offers the optimal piston ring or piston ring pack for every engine. The broad range of products includes compression rings and oil control rings in various designs, profiles, and technologies.
