Supertech 81mm High Performance Gas Nitrided Piston Rings - 1x3.10 / 1.2x3.40 / 2.8x3.10mm (R81-GNH8100)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Engineered for high-stress racing and street applications, these Supertech 81mm High Performance Piston Rings provide the superior sealing and oil control required for forced induction or high-RPM engine builds. The gas nitrided surface treatment significantly increases surface hardness and wear resistance, reducing friction while preventing ring land galling under extreme cylinder pressures.
This ring set is precision-machined to exact tolerances, ensuring consistent radial tension and optimal heat transfer from the piston crown to the cylinder wall. These rings are designed to satisfy the demands of professional engine builders looking for long-term durability and reliable compression under load.
- Bore Diameter: 81mm
- Top Ring: 1.0mm x 3.10mm (Gas Nitrided)
- Second Ring: 1.2mm x 3.40mm
- Oil Ring: 2.8mm x 3.10mm
- Finish: Gas Nitrided for reduced friction and high heat resistance
- Manufacturer Part Number: R81-GNH8100
