Supertech 84.5mm Bore Piston Rings - 1x3.10 / 1.2x3.5 / 2.8x3.10mm High Performance Gas Nitrided

Supertech is known for making well-built engine components for performance applications. These piston rings are designed for an 84.5mm bore and feature a high-performance gas nitrided finish. The specific ring sizes are 1x3.10mm for the top ring, 1.2x3.5mm for the second ring, and 2.8x3.10mm for the oil ring.

The gas nitriding process hardens the surface of the rings, which helps them resist wear and maintain a good seal against the cylinder wall. This is important for keeping combustion pressure contained and preventing oil from entering the combustion chamber. These rings are a solid option when you're rebuilding an engine and need reliable components for a proper seal.
