Mahle Rings Performance Gas Nitride Steel 4.180 x .043 .157 RW Plain Ring Set

This set includes Mahle OE Performance Gas Nitride Steel Piston Rings, designed for a 4.180 bore with .043 top ring, .157 oil ring, and RW (Race/Performance) configuration. These rings are built for demanding engine applications where improved sealing and durability are key.

The nitride steel construction offers solid wear resistance, especially important for performance builds where cylinder pressures and temperatures can be higher. The .043 top ring is a common size for performance applications, allowing for good sealing and heat transfer. The RW configuration indicates these are intended for engines that see more aggressive use, aiming for better compression and oil control under stress.

When rebuilding or modifying an engine, ensuring proper ring seal is crucial for performance and longevity. These Mahle rings are a well-built option for those looking to get the most out of their engine build.
