Supertech 80mm Bore Piston Rings - 1x3.10 / 1.2x3.40 / 2.8x3.10mm High Performance Gas Nitrided

These Supertech piston rings feature a gas nitrided finish, a process that hardens the surface to resist wear and improve durability. The ring set is designed for an 80mm bore and includes three distinct ring sizes: 1x3.10mm for the top ring, 1.2x3.40mm for the second ring, and 2.8x3.10mm for the oil ring. This specific sizing is crucial for achieving a proper seal within the cylinder bore, which directly impacts engine performance and efficiency.

The high-performance gas nitriding treatment is a notable detail, as it creates a very hard, wear-resistant surface. This helps the rings maintain their sealing ability over time, even under demanding operating conditions. Proper ring seal is essential for preventing combustion gases from escaping the cylinder and for controlling oil consumption, both of which are critical for engine health and power output.

When rebuilding an engine, selecting the correct piston ring set is vital. These Supertech rings are a solid option for builds where a reliable seal and long-term durability are priorities. Please note that these rings are not CARB approved and cannot be shipped to California.
