What is the primary function of these piston rings?

These piston rings are crucial for sealing the combustion chamber to prevent gas leakage, controlling oil consumption by scraping excess oil from the cylinder walls, and helping to transfer heat from the piston to the cylinder wall for cooling.

What does 'ductile plasma moly' construction mean for these rings?

The ductile iron base provides a strong and flexible ring that can conform to the cylinder wall. The plasma moly coating adds a layer of hardness and wear resistance, helping the rings last longer and maintain a good seal under operating stress.

Are these rings suitable for all engine builds?

This set is designed for a 4.045 inch bore and features standard tension. It's important to ensure these specifications match your engine's requirements and the intended build type. They are not CARB approved and cannot be shipped to California.

Product Details

This is a standard tension piston ring set from Mahle OE, designed for a 4.045 inch bore. It features a ductile plasma moly construction, with ring dimensions of 1.5mm for the top and second rings, and 3.0mm for the oil ring. These rings are essential for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall.

The plasma moly coating on these rings is known for its hardness and wear resistance, which helps them hold up well in demanding engine conditions. The ductile iron base provides strength and flexibility, ensuring a good seal against the cylinder wall even as the engine heats and expands. This set is built for standard tension applications, meaning it's designed to provide a balanced seal without excessive drag.

When rebuilding an engine, choosing quality piston rings is critical for performance and longevity. This Mahle OE set offers a well-built option for your engine build, ensuring proper sealing and oil control.
