Supertech 86mm Bore Piston Rings - 1x3.10 / 1.2x3.5 / 2.8x3.10mm High Performance Gas Nitrided

These Supertech piston rings feature a gas nitrided surface treatment, a process that hardens the ring's outer layer to resist wear and improve durability. The set includes rings with specific dimensions: the top ring is 1x3.10mm, the second ring is 1.2x3.5mm, and the oil ring is 2.8x3.10mm, designed to fit an 86mm bore engine.

Gas nitriding is a heat-treating process that introduces nitrogen into the surface of the metal, creating a tough, wear-resistant layer without significantly changing the ring's overall dimensions. This makes them a solid option for high-performance gas applications where consistent sealing and longevity are important. Proper installation is key to ensuring these rings perform as intended and seal effectively against the cylinder wall.
