Mahle Rings Plasma Moly Steel Top Comp Ring 4.5675 x .0625in .190in RW Ring Set (48 Qty Bulk Pack)

Mahle is a well-known name in engine components, often supplying parts directly to vehicle manufacturers. This bulk pack of 48 top compression rings is designed for serious engine rebuilding projects where precision and durability are key. These rings are crafted from plasma moly steel, a material chosen for its strength and wear resistance, especially under high operating temperatures.

Each ring measures 4.5675 inches in diameter with a thickness of 0.0625 inches and a profile of 0.190 inches. The plasma moly coating is a notable feature, helping to reduce friction and improve sealing between the piston and cylinder wall. This advanced surface treatment is crucial for maintaining compression and preventing blow-by, especially in performance or heavy-duty applications. This bulk pack is ideal for shops or builders working on multiple engines or larger fleet projects, ensuring you have a consistent supply of high-performance rings on hand.

When rebuilding an engine, the piston rings are critical for sealing the combustion chamber, controlling oil consumption, and transferring heat. Using well-built rings like these from Mahle OE helps ensure the longevity and performance of your rebuilt engine. Please note that these rings are not CARB approved and cannot be shipped to California.
