Mahle Rings 4.135in Bore 1/16in 3.00MM Plasma Moly Ductile Std Tension Engine Set Moly Ring Set

In this Mahle OE engine set, you get a complete set of piston rings designed for a 4.135-inch bore. These rings feature a plasma moly coating on the top ring for improved durability and reduced friction, paired with ductile iron for the other rings. They are set to standard tension, which is crucial for proper sealing against the cylinder wall.

This set is built with a focus on reliable engine operation. The plasma moly coating on the top compression ring is a notable detail; it's known for its ability to withstand heat and wear, helping to maintain a good seal over time. Ductile iron is used for its strength and resistance to breakage, making these rings a solid option for engine rebuilds where durability is key. They are designed to fit right and perform as expected in standard tension applications.

Please note that this ring set is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for detailed installation procedures and specifications.
