Technical Details and Material Specifications

The E-468K piston ring set is manufactured to precise standards, featuring a top ring with a keystone face design that helps reduce ring sticking and improve sealing under combustion pressure. The top ring is made from steel with a molybdenum coating, which enhances wear resistance and durability. The second ring uses grey iron material with a reverse torsional face design to provide effective scraping of excess oil and maintain compression. The oil ring is a 3-piece flex vent type, 4.00 mm wide, designed to optimize oil control and reduce oil consumption. This set is intended for engines with a bore diameter of 101 mm (3.9764 inches) and is not a file fit, meaning it is ready for installation without additional fitting.
