Mahle Rings Performance Plasma Moly Steel Top Compression Ring 4.610 x 1.0MM .143 RW Moly Ring Set

This is a Mahle OE Performance Plasma Moly Steel Top Compression Ring Set, part number 3011024. These rings are designed for engines where improved sealing and durability are key. The plasma moly coating on the top compression ring is a tough, wear-resistant surface that helps reduce friction and extend ring and cylinder wall life. This is important for maintaining good compression and oil control over time.

The rings are made from steel, which offers good strength and resilience. The specific dimensions, 4.610 inches in bore size with a 1.0mm thickness and a .143 inch ring width, indicate they are intended for a specific engine build where precise fitment is crucial for optimal performance. Mahle is a well-known name in engine components, and this set reflects their focus on providing durable parts for engine rebuilding.

Please note that this ring set is not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual for proper installation procedures and specifications.
