Supertech 84mm 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 84mm bore and feature a high-performance gas nitrided finish. Nitriding is a surface hardening process that improves wear resistance and durability, which is crucial for keeping your engine running smoothly under stress.

The ring set includes three distinct ring sizes: a 1x3.10mm top ring, a 1.2x3.5mm second ring, and a 2.8x3.10mm oil ring. This specific sizing is important for proper sealing within the cylinder bore, helping to maintain compression and control oil consumption. They are a solid option if you're rebuilding or modifying an engine and need reliable piston rings that can handle increased performance demands.
