Mahle Rings Performance Gas Nitride Steel 4.145 x .043 .157 RW Plain Ring Set

These Mahle piston rings are made from nitride steel, a material chosen for its ability to withstand the heat and stress inside an engine cylinder. The nitride treatment hardens the surface, which helps them resist wear and maintain a good seal against the cylinder wall over time. They're designed for a 4.145-inch bore, and the ring set features a .043 inch thickness for the top and second rings, with a .157 inch oil ring width.

This set is intended for performance gas applications where a solid seal is crucial for efficient combustion and power. The plain ring design is a straightforward approach that focuses on reliable sealing. When you're rebuilding an engine, getting the piston rings right is key to ensuring the engine runs smoothly and lasts. These Mahle rings are a well-built option for that critical job.
