Mahle Rings Performance Plasma Steel Top Ring 3.835in x 1.0MM .143in RW HVOF Moly Ring Set

If you're rebuilding the top end of your engine, getting the right piston rings is crucial for sealing and performance. These Mahle OE rings are built for that job. The top ring is made from plasma-sprayed steel, which is a strong material that holds up well under heat and pressure. This plasma coating helps create a solid seal against the cylinder wall, which is key for keeping combustion pressure where it belongs and preventing oil from getting into the combustion chamber.

The 1.0mm thickness of the top ring and the .143 inch ring groove width are standard dimensions for many performance applications, ensuring a good fit in the piston groove. Mahle is a well-known name in engine components, and these rings are made to meet the demands of an engine rebuild where reliability and proper function are the main goals. They are designed to work with a 3.835 inch bore size, so make sure that matches your engine's specifications.
