Mahle Rings Gas Nitride Steel Performance Top Compression Ring 4.255 x .043 .170 RW Plain Ring Set

Mahle OE offers this performance top compression ring set, designed for engines needing a reliable seal. These rings are made from nitride steel, a material chosen for its ability to withstand the heat and pressure found in performance applications. The specific dimensions, 4.255 inches bore size with a .043 inch thickness and .170 inch height, are critical for ensuring a proper fit and seal within the cylinder bore. A good seal is essential for maintaining compression, preventing oil from entering the combustion chamber, and ensuring efficient engine operation.

The nitride treatment on these steel rings adds a layer of hardness and wear resistance. This is important because the top compression ring is subjected to the most extreme conditions in the cylinder. By using well-built components like these, you help ensure your engine runs smoothly and efficiently. This set is intended for specific engine builds where precise ring dimensions and durable materials are a priority.
