Supertech 81.5mm Gas Nitrided Piston Rings - 1.0x3.1 / 1.2x3.4 / 2.8x3.1mm - R81.5-GNH8150
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Supertech high-performance piston rings are engineered for demanding engine builds that require superior sealing under extreme cylinder pressures. This ring set features a gas nitrided finish, providing an exceptionally hard surface that reduces friction and increases wear resistance for extended service life in turbocharged, supercharged, or high-compression naturally aspirated applications.
- Bore Diameter: 81.5mm
- Top Ring: 1.0mm x 3.10mm
- Second Ring: 1.2mm x 3.40mm
- Oil Ring: 2.8mm x 3.10mm
- Finish: High-performance gas nitrided coating
- Part Number: R81.5-GNH8150
Designed for precise fitment and optimal oil control, these rings help minimize blow-by and maintain consistent compression. Ensure cylinder walls are honed to the proper finish according to manufacturer specifications to facilitate correct ring seating.
