Mahle Rings Performance Plasma Steel Top Ring 3.556in x 1.0MM .143in RW HVOF Moly Ring Set

Mahle OE is a well-known name for dependable engine parts, and this piston ring set continues that tradition. If you're rebuilding an engine, getting the right piston rings is crucial for proper sealing and performance. These top rings are made from plasma-treated steel, which offers improved wear resistance compared to standard cast iron rings. The HVOF Moly coating further enhances their durability and helps them seat properly against the cylinder wall.

This set is designed for a 3.556-inch bore diameter and features a 1.0mm top ring thickness with a 0.143-inch wire gap. The plasma treatment and Moly coating work together to create a strong seal, helping to maintain compression and prevent oil from entering the combustion chamber. Proper ring function is key to an engine's overall health and efficiency.
