Mahle Rings Performance Plasma Steel Top Ring 4.085in x 1.0MM .143in RW HVOF Moly Ring Set

Mahle OE is a well-known name for dependable engine parts, and these performance plasma steel top rings carry that reputation forward. Designed for demanding applications, these rings are built to handle the heat and pressure found in high-performance engines. The plasma-sprayed steel construction offers improved durability over standard cast iron rings, while the 1.0MM thickness is a common spec for many performance builds. The 4.085-inch bore size ensures a precise fit for the intended application.

These rings feature an HVOF (High-Velocity Oxygen Fuel) moly coating, which is a tough, wear-resistant surface treatment. This coating helps reduce friction and wear on both the ring and the cylinder wall, contributing to a longer engine life and consistent sealing. When rebuilding or upgrading your engine, choosing well-built components like these Mahle rings is key to achieving reliable performance and longevity.
