Cylinder Liners

Cylinder Liners, found within the Engine Parts > Crankcase section, are critical components responsible for forming the inner surface of each cylinder in an internal combustion engine of passenger cars and commercial vehicles. These precision-engineered sleeves provide a durable and replaceable wear surface for the piston rings, maintaining compression and ensuring efficient engine operation. Cylinder liners are typically constructed from cast iron or specialized alloys for high wear resistance and thermal conductivity. Replacing worn cylinder liners restores engine power and reduces oil consumption. Examples in our catalog include MAHLE liners like MPN 037AY00106090 and 2096290, as well as options from MAN such as MPN 51.01201-0417.
