Supertech High Performance Gas Nitrided Piston Rings

Optimize your engine's efficiency and power output with these Supertech piston rings, precision-engineered for an 84.5mm bore. These high-performance rings are gas nitrided, a surface hardening process that significantly enhances their resistance to wear, friction, and heat. This advanced treatment ensures a superior seal between the piston and cylinder wall, minimizing blow-by, reducing oil consumption, and maximizing compression for peak performance.

Key Features:

  • Bore Size: 84.5mm
  • Ring Set Configuration: 1x3.10mm (Top Ring), 1.2x3.5mm (Second Ring), 2.8x3.10mm (Oil Ring)
  • Material & Treatment: Premium steel construction with gas nitriding for exceptional hardness and longevity.
  • Performance Benefits: Delivers enhanced power, improved fuel economy, better oil control, and extended engine life under demanding conditions.
  • Application: Essential for performance engine builds, racing applications, and any vehicle requiring robust internal engine components.

Manufactured with Supertech's commitment to quality, these 84.5mm piston rings are built to withstand the rigors of high-performance driving. The gas nitrided surface provides a tough, durable finish that maintains its integrity under extreme temperatures and pressures. Upgrade your engine's internals with reliable components from GGCRACING.
