Mahle Rings 4.1650 Bore Dia 1/16in Edge Width Grey Iron THG Second Ring Plain Ring Set

When you're rebuilding the top end of your engine, getting the right piston rings is crucial for proper sealing and compression. These Mahle OE piston rings are designed for a 4.1650 inch bore, ensuring a precise fit in your cylinders. They are made from grey iron, a material known for its good wear resistance and ability to handle the heat and pressure inside an engine.

The THG second ring is a plain design, which helps to scrape excess oil from the cylinder wall as the piston moves. This helps prevent oil from getting into the combustion chamber, which can cause smoking and poor performance. Mahle is a well-known name in engine components, and these rings are built to meet original equipment specifications, meaning they'll perform as expected in your application.
