Mahle Rings 4.125in Bore .043in1/16in 3.00MM Plasma Moly Ductile Std Tension Reduced Moly Ring Set

This is a Mahle OE piston ring set designed for engines with a 4.125 inch bore. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. This set features plasma moly ductile iron top rings, which are known for their durability and wear resistance, especially in demanding applications. The standard tension design ensures a good seal against the cylinder wall.

The top rings measure .043 inches, and the second and oil rings are 1/16 inch and 3.00MM respectively. This specific sizing is important for proper fitment and function within the piston groove. The plasma moly coating on the top rings helps reduce friction and improve longevity, making them a solid choice for engine rebuilds where reliability is key. These rings are designed to fit right and perform as expected.

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