Supertech 89.20mm Bore 1.0x3.30 / 1.2x3.70 / 2.8x3.30mm High Performance Gas Nitrided Piston Rings

Supertech is known for making well-built engine components, and these high-performance piston rings are no exception. These rings are designed for an 89.20mm bore and feature a gas nitrided finish for improved durability. The specific ring dimensions are 1.0x3.30mm for the top ring, 1.2x3.70mm for the second ring, and 2.8x3.30mm for the oil ring.

The gas nitriding process hardens the surface of the rings, making them more resistant to wear and heat. This is important for maintaining a good seal between the piston and cylinder wall, which is crucial for engine performance and longevity. These rings are a solid option if you're rebuilding an engine and need reliable components.
