What is the purpose of the plasma moly coating?

The plasma moly coating on the top ring is designed to improve wear resistance and reduce friction. This helps the rings seat properly and maintain their performance over time, especially in demanding engine conditions.

Are these rings suitable for all engine builds?

These rings are designed for a 4.155-inch bore with standard tension and reduced radial tension. They are a solid option for many engine rebuilds, but it's always best to confirm they match your specific engine's requirements.

Can these rings be shipped to California?

No, these rings are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're rebuilding the engine in your vehicle and need to ensure a solid seal between the piston and cylinder wall, this Mahle piston ring set is a strong option. These rings are designed for a 4.155-inch bore and feature a standard tension setup, which is common for many performance and heavy-duty applications. They are crucial for maintaining compression, controlling oil consumption, and transferring heat from the piston to the cylinder wall.

Mahle has built these rings with a ductile iron base, known for its strength and durability. The plasma moly coating on the top ring is a notable feature, offering improved wear resistance and reduced friction. This coating helps the rings seat properly and maintain their performance over time, especially under demanding conditions. The reduced radial tension design helps to minimize cylinder wall wear while still providing an effective seal.

This set is intended for standard engine builds where reliable performance and longevity are key. Remember that these rings are not CARB approved and cannot be shipped to California.
