Product Details

This Mahle OE piston ring set includes everything you need to outfit a set of pistons for a 4.030-inch bore. You get the top compression rings, second compression rings, and oil control rings, all designed to work together for a solid seal. The top rings are plasma moly coated, which is a well-known material for its durability and ability to reduce friction against the cylinder wall. The second rings are made from ductile iron, offering good strength and resistance to blow-by.

This set is built with standard tension for reduced radial tension, which helps minimize drag on the piston and can contribute to improved fuel economy. The oil control rings are also designed to manage oil effectively, preventing excess oil from entering the combustion chamber. Mahle has been a trusted name in engine components for a long time, and these rings are a well-built option for rebuilding or refreshing your engine.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for installation procedures and recommended clearances.
