Mahle Rings 3.8090in X 1.5MM Edge Width Moly Ductile Top Ring Moly Ring Set

This Mahle OE Piston Ring Set features a 1.5mm edge width on the top ring, which is constructed from moly ductile iron. This specific design choice is important for how the ring seals against the cylinder wall, helping to maintain proper compression and oil control within the engine. Mahle is a well-known name in engine components, and this set is built to meet the demands of engine rebuilding.

The moly coating on the top ring is a practical detail that helps reduce friction and wear, especially during the critical break-in period after an engine rebuild. This can lead to a longer lifespan for both the rings and the cylinder walls. When you're putting an engine back together, getting the piston rings right is crucial for performance and reliability, and this set from Mahle OE is a solid option for that job.
