Mahle Rings 4.3800in X .017in Plasma-Moly Dykes Ductile Top Compression Ring Moly Ring Set

Mahle is known for making reliable engine parts that meet original equipment standards. This set of top compression rings is designed to fit your engine precisely, helping to restore proper cylinder sealing. They feature a plasma-moly Dykes design for the top ring, which is a common and effective way to ensure a good seal against the cylinder wall.

These rings are made from ductile iron, a strong material that can handle the pressures inside the combustion chamber. The .017 inch thickness is a standard size for many applications, and the moly coating on the top ring helps with break-in and reduces friction. Proper ring seal is crucial for engine performance, oil control, and fuel efficiency, so replacing worn rings with a well-made set like these can make a noticeable difference.
