JE Pistons Individual Ring Top Ring - Steel Nitrided Top Ring

JE Pistons is well-known for making strong internal engine components. This is their steel nitrided top ring, designed for a 1.2mm groove size. It’s a solid choice if you’re rebuilding an engine and need a reliable top ring to seal combustion gases.

This ring is made from steel and has a nitride coating. Nitriding is a heat-treating process that hardens the surface, which helps it resist wear and maintain a good seal against the cylinder wall. This is important for keeping combustion pressure where it belongs and preventing blow-by, which can hurt performance and efficiency. It fits a 1.2mm ring groove, a common size for many performance and stock applications.
