Mahle Rings Performance 4.085in x 1/16in .190inRW D-Wall Plasma Moly Steel UCR Chrome Ring Set

Mahle OE is a well-known name for dependable engine parts, and these performance piston rings carry that reputation forward. Designed for a 4.085-inch bore, they feature a specific ring land depth and width, with a D-wall construction for improved sealing. The top ring is chrome-plated for durability, while the second ring has a plasma moly face, a tough coating that helps reduce friction and wear. This combination is built to handle the demands of performance applications, ensuring a solid seal between the piston and cylinder wall.

The materials and design here focus on creating a strong seal and lasting performance. The steel construction offers good resilience, and the plasma moly on the second ring is a popular choice for its wear resistance. This set is intended to work within the piston's ring groove, helping to manage combustion pressure and oil control effectively. If you're rebuilding an engine where performance and durability are key, these rings are a solid option.
