Mahle Rings Plasma Moly Steel Top Comp Ring 4.160in x .0625in .190in RW Ring Set (48 Qty Bulk Pack)

When you're rebuilding a performance engine or working on a high-volume shop project, getting the right piston rings is critical for sealing and power. This bulk pack of 48 top compression rings from Mahle OE is designed for a 4.160-inch bore and features a .0625-inch thickness and .190-inch ring groove depth. These are plasma moly steel rings, a popular choice for their durability and ability to handle the heat and stress of demanding engine builds.

Mahle is a well-known name in engine components, and these rings are built to perform. The plasma moly coating on the top compression ring helps reduce friction and wear, which is essential for maintaining good cylinder sealing and preventing premature wear, especially in engines that see a lot of use or are built for higher performance. This bulk pack is ideal for engine builders or shops that frequently work on engines with this specific bore size, ensuring you have plenty on hand for multiple projects. They are designed to fit standard .190-inch ring grooves.

It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to your specific engine build requirements and manufacturer recommendations to ensure these rings are the correct choice for your application.
