Mahle MS 4.125in 3.0MM Oil Ring Rails

These Mahle oil ring rails are built to a 3.0mm width and a 4.125-inch diameter, making them a precise fit for many engine rebuilds. They work with the oil control ring to manage how much oil stays on the cylinder walls, which is crucial for proper lubrication and preventing excess oil from getting into the combustion chamber.

Mahle is a well-known name in engine components, and these rails are made to meet the demands of keeping your engine running smoothly. They are designed to work as part of a complete ring set, ensuring consistent tension and sealing against the cylinder wall. Proper oil control is key to engine longevity and performance, and these rails play an important role in that system.
