Supertech 88.5mm Bore Piston Rings - 1x3.30 / 1.2x3.60 / 2.8x3.30mm High Performance Gas Nitrided

This set includes Supertech high performance gas nitrided piston rings, specifically sized for an 88.5mm bore. The ring set features a 1x3.30mm top ring, a 1.2x3.60mm second ring, and a 2.8x3.30mm oil ring. These rings are gas nitrided, a surface hardening process that improves wear resistance and durability, making them a solid choice for high-performance gas engines.

The nitriding process creates a tough outer layer on the rings, which helps them withstand the rigors of combustion and friction within the cylinder. This updated design aims to maintain a good seal between the piston and cylinder wall, which is crucial for efficient engine operation, power output, and oil control. Proper sealing helps prevent combustion gases from escaping into the crankcase and oil from entering the combustion chamber.
