Mahle MS Piston Ring 1cyl. 86.60 mm 1.2, 1.2, 2.8mm File-Fit Rings

This set includes one cylinder's worth of Mahle MS piston rings, designed for an 86.60mm bore. You get the top compression ring, second compression ring, and the oil control ring, all ready for file-fitting to your specific piston and cylinder dimensions. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall.

Mahle is a well-known name in engine components, and these rings reflect that reputation. They are made from durable materials designed to withstand the heat and pressure inside an engine cylinder. The file-fit design means you have the flexibility to precisely gap the rings yourself, which is often necessary for performance builds or when working with custom pistons. This ensures a tight seal and optimal performance for your engine rebuild.

When installing these rings, remember that file-fitting is a critical step. Take your time to ensure the correct end gap for your application, as this directly impacts engine performance and longevity. Always refer to your engine's specific service manual for detailed installation procedures and recommended ring gap specifications.
