Mahle Rings Plasma Moly Steel Top Comp Ring 4.150in x .0625in .190in RW Ring Set (48 Qty Bulk Pack)

Mahle is a well-known name in the automotive industry, particularly for their engine components. This specific product is a bulk pack of 48 top compression rings, designed for a 4.150-inch bore with a .0625-inch thickness and a .190-inch ring depth. These are the rings that seal the combustion chamber, playing a critical role in engine performance and efficiency.

These rings feature a plasma moly steel construction, which is a strong and durable material chosen for its ability to withstand the high temperatures and pressures of combustion. The plasma moly coating helps reduce friction between the piston ring and the cylinder wall, which can lead to improved engine life and potentially better oil control. This bulk pack is ideal for engine builders or shops that frequently work on engines requiring this specific ring size, ensuring you have plenty on hand for multiple builds or larger projects. The RW designation indicates a specific ring design, often related to its tension or sealing characteristics.

When rebuilding an engine, selecting the right piston rings is crucial for proper sealing and long-term reliability. These Mahle rings are a solid option for many performance and heavy-duty applications where a 4.150-inch bore is specified. Please note that these rings are not CARB approved and cannot be shipped to California.
