Supertech 87mm Bore Piston Rings - 1x3.30 / 1.2x3.60 / 2.8x3.30mm High Performance Gas Nitrided

These Supertech piston rings feature a gas nitrided finish, a hardening process that makes the surface exceptionally durable and wear-resistant. This treatment is crucial for high-performance gas engines, as it helps the rings maintain a tight seal against the cylinder wall under demanding conditions. The specific ring sizes are 1x3.30mm for the top ring, 1.2x3.60mm for the second ring, and 2.8x3.30mm for the oil control ring, all designed to fit an 87mm bore.

The nitriding process creates a tough outer layer that can withstand higher temperatures and pressures, which is important for engines that see a lot of action. This well-built set is designed to help your engine run efficiently by minimizing blow-by and ensuring proper oil control, contributing to consistent power output and longevity. They are a solid option when you're rebuilding or refreshing an engine that requires precise ring sealing.
