Supertech 83.5mm Bore Piston Rings - 1x3.10 / 1.2x3.5 / 2.8x3.10mm High Performance Gas Nitrided

Supertech is known for making well-built engine components, and these high-performance piston rings are no exception. Designed for an 83.5mm bore, these rings feature a gas nitrided finish, which is a surface hardening process that helps them stand up to the rigors of combustion. The specific ring groove dimensions are 1x3.10mm for the top ring, 1.2x3.5mm for the second ring, and 2.8x3.10mm for the oil ring, ensuring a precise fit in compatible pistons.

The nitriding process on these rings makes them more resistant to wear and scuffing compared to standard rings. This improved durability is crucial for maintaining a good seal between the piston and cylinder wall, which directly impacts engine performance and longevity. They are a solid option when rebuilding or refreshing an engine where a reliable seal is paramount.
