Supertech 85mm Bore Piston Rings - 1x3.10 / 1.2x3.5 / 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 an 85mm bore, ensuring a tight fit against the cylinder wall.

The gas nitriding process hardens the surface of these rings, making them more resistant to wear and heat. This is important for engines that see hard use, as it helps maintain a good seal between the piston and cylinder wall, which is key for both power and longevity. The ring set includes the specific dimensions you need for a standard 85mm piston: a 1mm top ring, a 1.2mm second ring, and a 2.8mm oil ring.

Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's service manual for proper installation procedures and specifications.
