Supertech 77.5mm Bore Piston Ring Set - 1x3.1 / 1.2x3.4 / 2.8x3.1mm Gas Nitrided - R77.5-GNH7750
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Engineered for high-performance applications, this Supertech piston ring set is designed for engines with a 77.5mm bore. These rings feature a gas nitrided finish, providing an exceptionally hard, wear-resistant surface that reduces friction and maintains a superior cylinder seal under extreme thermal and mechanical loads.
This specific ring pack is optimized for precise oil control and compression retention in demanding environments, making it an ideal choice for high-RPM or forced induction builds. The gas nitriding process ensures the rings can withstand the rigors of racing while extending the service life of both the rings and the cylinder walls.
- Bore Size: 77.5mm
- Top Ring: 1.0mm x 3.1mm
- Second Ring: 1.2mm x 3.40mm
- Oil Ring: 2.8mm x 3.10mm
- Finish: High Performance Gas Nitrided
- MPN: R77.5-GNH7750
