Mahle Rings Plasma Moly Steel Top Comp Ring 4.145in x .0625in .190in RW Ring Set (48 Qty Bulk Pack)

This bulk pack gives you 48 Mahle OE Plasma Moly Steel Top Compression Rings, each measuring 4.145 inches in bore diameter and 0.0625 inches thick. These rings are a critical component for any engine rebuild, especially when you're looking to restore or enhance the performance of your engine's combustion chamber. The top compression ring is the first line of defense against combustion gases escaping past the piston, and its proper function is key to maintaining compression, sealing the cylinder, and controlling oil consumption.

Mahle has built a strong reputation for producing well-made engine components, and these rings are no exception. They are constructed from plasma moly steel, a material chosen for its durability and wear resistance. The plasma moly coating further enhances this by providing a tough, low-friction surface that helps the rings seat properly against the cylinder wall and resist scuffing. This means you can expect improved sealing and longer ring life, even under demanding operating conditions. The 0.190 inch ring height is a specific dimension to match certain piston designs, ensuring a precise fit within the piston groove.

This is a bulk pack designed for shops or builders working on multiple engines or performing extensive rebuilds. It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to your specific engine's service manual for detailed installation procedures and recommended clearances to ensure optimal performance and longevity.
