Product Details
Mahle's MS 4.040-4.080 oil ring support rail is made from a durable steel material, measuring 2mm thick. This component plays a crucial role in maintaining the integrity of your oil control ring assembly, especially in engines that experience significant thermal expansion or high operating temperatures. By providing a solid foundation, it helps prevent the oil ring from collapsing or deforming under stress, ensuring consistent oil scraping and preventing oil from entering the combustion chamber.
This support rail is designed to fit a range of piston sizes, indicated by the 4.040-4.080 specification, making it a versatile option for engine rebuilds. Its well-built construction aims to restore proper oil control and maintain engine health. While it's a universal part, always confirm compatibility with your specific piston and ring set during your engine build.
