The top ring is crafted from carbon steel with a 1.50 mm axial height, providing a strong seal against combustion gases. The second ring, made from cast iron and also 1.50 mm thick, assists in scraping excess oil from the cylinder walls. The oil ring assembly uses stainless steel in a shallow groove design with a 2.80 mm thickness to maintain proper lubrication without excessive oil consumption. The chrome face coating on the piston rings enhances wear resistance and extends service life.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis piston ring set is compatible with a range of Infiniti, Mercury, and Nissan vehicles, including:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInfiniti 200SX, 300ZX, J30, M30, Maxima, Pathfinder, Quest, Villager\u003c\/li\u003e\n\u003cli\u003eMercury models compatible with the specified bore diameter\u003c\/li\u003e\n\u003cli\u003eNissan D21 and other listed models\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIt is designed for use in engine cylinder block components where a bore diameter of 3.425 inches is specified, making it suitable for maintenance or engine rebuilds on these vehicles.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by This Piston Ring Set\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduced compression due to worn or damaged piston rings\u003c\/li\u003e\n\u003cli\u003eExcessive oil consumption caused by ineffective oil ring sealing\u003c\/li\u003e\n\u003cli\u003eIncreased blow-by and engine performance loss\u003c\/li\u003e\n\u003cli\u003eEngine smoke resulting from poor piston ring sealing\u003c\/li\u003e\n\u003cli\u003eWear and tear from standard piston ring materials and coatings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the cylinder bore diameter matches the 3.425-inch specification before installation.
