What material are these piston rings made from?

The top rings are made from ductile iron with a plasma moly coating. This combination offers good strength and improved wear resistance in the cylinder bore.

Are these rings suitable for all engines?

These rings are specifically designed for engines with a 4.040-inch bore. It's important to verify your engine's bore size before purchasing.

Can these rings be shipped to California?

Product Details

Mahle is known for making solid OE replacement parts, and this ring set is no different. If you're rebuilding an engine and need to replace your piston rings, this set is built to get your engine running right again. These rings are designed for a 4.040-inch bore, which is a common size for many engines. They feature plasma moly ductile iron construction, which is a strong material that helps resist wear in the cylinder bore.

This set uses standard tension rings with a reduced radius, and the plasma moly coating on the top ring helps improve its durability and sealing ability. This means you can expect a good seal between the piston and cylinder wall, which is crucial for proper engine performance and oil control. While these are a standard replacement part, the plasma moly coating is a notable detail that adds to their longevity.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
