Mahle Rings Plasma Moly Steel Top Compression Ring 4.250in x .0625in .190in RW Moly Ring Set

This set includes Mahle OE Plasma Moly Steel Top Compression Rings designed for 4.250 inch bores. Each ring measures .0625 inches wide and features a .190 inch ring depth, with a RW Moly finish for improved durability and performance. These rings are a key component for rebuilding or refreshing your engine's top end, ensuring a proper seal between the piston and cylinder wall.

The plasma moly coating on these steel rings is known for its wear resistance, helping to extend the life of both the rings and the cylinder walls. This well-built construction is crucial for maintaining compression and preventing oil from entering the combustion chamber, which directly impacts engine efficiency and power output. Proper ring seal is essential for smooth engine operation and preventing blow-by.
