Supertech 79mm Bore Piston Rings - 1x2.9 / 1.2x3.40 / 2.8x3.10mm High Performance Gas Nitrided

If you're rebuilding the engine in your performance vehicle, getting the right piston rings is crucial for proper sealing and compression. These high-performance gas nitrided rings from Supertech are designed for a 79mm bore, ensuring a tight fit against the cylinder wall. The nitriding process hardens the surface of the rings, making them more resistant to wear and heat, which is important for engines that see a lot of use or are tuned for more power.

This set features specific dimensions: the top ring is 1x2.9mm, the second ring is 1.2x3.40mm, and the oil ring is 2.8x3.10mm. These precise measurements help achieve optimal sealing between the piston and cylinder wall, which is key for maintaining compression and preventing blow-by. The gas nitriding treatment is a notable feature that adds durability, helping these rings stand up to the demands of a performance gas engine.
