Mahle Rings Performance Plasma Moly Steel HV385 Top Ring 3.356in x 1.0MM .143in RW Moly Ring Set

These top rings are plasma moly steel, a tough material that holds up well to heat and friction. They measure 3.356 inches in bore size with a 1.0mm thickness and a .143 inch ring height, designed for performance applications where durability is key. This set is part of a rebuild kit, meant to ensure a good seal between the piston and cylinder wall for optimal engine function.

Mahle OE is known for making well-built engine components. This ring set is designed to provide a solid seal, helping to prevent blow-by and oil consumption. The plasma moly coating on the top ring adds an extra layer of wear resistance, which is important for engines that see regular use or are built for higher performance.
