Supertech 92.5mm Bore Piston Rings - 1x3.5 / 1.2x3.80 / 2.8x3.10mm High Performance Gas Nitrided

These Supertech piston rings feature a gas nitrided finish on the top ring, measuring 1x3.5mm, designed for improved durability and wear resistance in high-performance applications. The second ring is 1.2x3.80mm, and the oil ring is a 2.8x3.10mm set, all precisely sized for a 92.5mm bore. This specific sizing and nitriding process helps ensure a solid seal between the piston and cylinder wall, which is crucial for maintaining compression and controlling oil consumption.

The nitriding process hardens the surface of the top ring, making it more resistant to scuffing and wear, especially under the higher temperatures and pressures found in performance engines. This attention to material treatment and precise dimensions means these rings are well-suited for engine rebuilds where reliability and consistent performance are key. They are designed to fit right into the corresponding piston grooves for a straightforward installation during an engine overhaul.
