The Total Seal ML3690 5 piston ring set features gapless top rings made from ductile moly, offering excellent wear resistance and sealing properties. These low-tension rings are designed for race applications and come in a configuration of 1/16", 1/16", and 3/16" groove dimensions for an 8-cylinder engine. The bore size is 4.000" with an additional .005" for file fitting. Total Seal emphasizes precision, strength, lightness, and innovation in their piston rings, aiming to improve engine efficiency and durability. Some sets may include a dry film cylinder wall lubricant to aid in the critical break-in period, preventing ring-related cylinder wall burnishing and glazing.
