Supertech 80.5mm Bore Piston Rings - 1x3.10 / 1.2x3.40 / 2.8x3.10mm High Performance Gas Nitrided

These Supertech piston rings feature a gas nitrided surface treatment, a process that hardens the ring face to resist wear and improve durability. The specific ring sizes are 1x3.10mm for the top ring, 1.2x3.40mm for the second ring, and 2.8x3.10mm for the oil control ring, designed to fit an 80.5mm bore engine. This set is intended for high-performance gasoline applications where reliable sealing and consistent compression are critical.

The nitriding process creates a tough, wear-resistant layer on the ring surface, which helps maintain a good seal against the cylinder wall over time, even under demanding conditions. This is important for keeping combustion pressure contained and preventing blow-by, which can rob an engine of power and efficiency. The precise dimensions ensure they seat correctly within the piston grooves and cylinder bore for optimal performance.

When rebuilding an engine, choosing the right piston rings is crucial for the longevity and performance of the entire assembly. This set from Supertech is a solid option for builds focused on gasoline performance where a durable and well-sealed combustion chamber is the goal.
