Mahle Rings 4.3800in X 5/64in Moly Claimer Top Compression Ring Moly Ring Set

Mahle OE Moly Claimer Top Compression Rings are a solid option when you're rebuilding your engine. These rings are designed to seal combustion gases in the cylinder, which is crucial for getting the power and efficiency your engine was built for. The 'Moly Claimer' designation means they feature a molybdenum coating on the top compression ring, which helps reduce friction and wear, especially during the critical break-in period. This coating is well-known for its ability to handle the heat and stress of combustion.

This set is built to the exact specifications for a 4.3800-inch bore with a 5/64-inch top ring groove. Mahle has been a trusted name in engine components for a long time, and these rings reflect that experience. They are made to fit right and perform reliably, ensuring a good seal between your pistons and cylinder walls. Proper ring seal is key to preventing blow-by and maintaining consistent compression across all cylinders.
