Mahle Rings 3.7560in X 5/64in Edge Width Grey Iron RBT Std Gap Second Ring Plain Ring Set

These Mahle OE piston rings are made from grey iron, a material known for its good wear resistance and ability to handle heat. The 3.7560-inch bore size and 5/64-inch edge width are specific dimensions critical for proper sealing within the cylinder. They come with a standard gap, which is the most common setting for general engine rebuilding and ensures they can expand properly with heat without binding.

As a second ring in a piston ring set, this plain ring plays a key role in controlling oil consumption and maintaining compression. Its design focuses on providing a solid seal against the cylinder wall while working in conjunction with the compression ring above it and the oil control ring below. Mahle OE parts are built to meet the original equipment specifications, meaning they are designed to fit and function just like the parts that came with your vehicle from the factory.
