Supertech 94mm Bore Piston Rings - 1x3.5 / 1.2x3.90 / 2.8x3.10mm High Performance Gas Nitrided

The gas nitrided surface treatment on these Supertech piston rings is a key detail for high-performance gas engines. This process hardens the ring surface, making it more resistant to wear and reducing friction against the cylinder wall. This means they can handle the increased heat and stress found in performance applications, helping to maintain a good seal under demanding conditions.

Designed for a 94mm bore, these rings feature a specific three-piece set: a 1x3.5mm top ring, a 1.2x3.90mm second ring, and a 2.8x3.10mm oil ring. This precise sizing and configuration is crucial for proper sealing, oil control, and efficient combustion. The nitriding process ensures these rings will hold up over time, even when pushed harder than stock components.
