Mahle Rings 4.125in Bore .043in 3.00MM Plasma Moly Ductile Low Tension Reduced Rad Moly Ring Set

Mahle is known for making solid engine components, and this ring set is no exception. If you're rebuilding an engine and need to replace your piston rings, this set is built for a 4.125 inch bore. They feature plasma moly ductile iron construction, which is a strong material for this application. These rings are designed for low tension and reduced radial pressure, helping them seal well against the cylinder wall.

The plasma moly coating on these rings helps with durability and reduces friction. This means they can handle the heat and stress inside the combustion chamber while maintaining good sealing performance. They are a reduced radial design, which means they exert less pressure on the cylinder walls, potentially leading to longer engine life and better oil control.
