Supertech 75.5mm Bore Piston Rings - 1x2.70 / 1.2x3.20 / 2.8x2.70mm High Performance Gas Nitrided

Supertech is known for making well-built engine components, and these high-performance gas nitrided piston rings are a solid example. If you're rebuilding an engine with a 75.5mm bore, these rings are designed to help seal your combustion chamber effectively. The gas nitriding process hardens the surface, which can help them hold up better under the heat and pressure of combustion.

This set features a specific ring configuration: the top ring is 1x2.70mm, the second ring is 1.2x3.20mm, and the oil ring is 2.8x2.70mm. This precise sizing is important for proper sealing against the cylinder wall and piston groove, helping to prevent blow-by and oil consumption. Proper ring seal is crucial for maintaining compression and ensuring your engine runs smoothly and efficiently.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for installation procedures and any other required components for your rebuild.
