Supertech 82mm Bore Piston Rings - 1x3.10 / 1.2x3.40 / 2.8x3.10mm High Performance Gas Nitrided

These Supertech piston rings feature a gas nitrided surface treatment, a process that hardens the ring's face to resist wear and improve durability. This set is designed for an 82mm bore and includes three distinct ring sizes: 1x3.10mm for the top ring, 1.2x3.40mm for the second ring, and 2.8x3.10mm for the oil control ring. This specific sizing is common in many high-performance gas engine applications.

The nitriding process creates a tough outer layer on the rings, which helps them withstand the high temperatures and pressures found in performance engines. This improved wear resistance means the rings can maintain a good seal against the cylinder wall for longer, contributing to consistent compression and efficient combustion. They are a well-built component for engine rebuilds where reliability and performance are key.
