Supertech 93.00mm Bore Piston Rings - 1x3.50 / 1.2x3.90 / 2.8x3.10mm 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. Designed for a 93.00mm bore, they feature a specific ring groove sizing: 1x3.50mm for the top ring, 1.2x3.90mm for the second ring, and 2.8x3.10mm for the oil ring. This precise sizing is crucial for proper sealing and oil control within the cylinder.

The gas nitriding process hardens the surface of the rings, making them more resistant to wear and heat. This is important for engines that see frequent use or higher operating temperatures. These rings are intended for gas applications where reliable sealing and durability are key. Please note that these rings are not CARB approved and cannot be shipped to California.
