Technical Details and Material Specifications

The E-553K piston ring set is crafted to provide effective sealing and oil control in engines such as those found in Chevrolet C1500, C2500, and GMC Savana 3500 models. The top ring uses a steel base with a molybdenum coating, which reduces wear and improves ring life. Its barrel face design helps maintain a consistent seal under varying operating conditions. The second ring is made from grey iron and features a reverse torsional face design to aid in scraping excess oil from the cylinder walls. The oil ring is a 3-piece flex vent type, 3/16 inch wide, designed to optimize oil distribution and prevent oil consumption. The set is manufactured to standard size specifications with a bore diameter of 4.2500 inches and groove widths of 5/64 x 5/64 x 3/16 inches, ensuring compatibility with specified engine blocks.
