What materials are these piston rings made from?

These Mahle piston rings are constructed from ductile iron. The top ring is further enhanced with a plasma moly face, which is known for its durability and friction-reducing properties.

What is the purpose of the plasma moly coating?

The plasma moly coating on the top ring helps to improve wear resistance and create a better seal against the cylinder wall. This can lead to improved engine performance and a longer lifespan for the rings and cylinder.

Are these rings suitable for all engine builds?

These are high-tension rings designed for specific bore sizes and applications. It's important to verify that the 4.187-inch bore size and the ring dimensions match your engine's specifications. They are not CARB approved and cannot be shipped to California.

Product Details

This Mahle OE ring set includes all the piston rings you need for your engine rebuild. Specifically, you get rings designed for a 4.187-inch bore, featuring a 1/16-inch top ring, a 1/16-inch second ring, and a 3/16-inch oil ring. These are high-tension rings, built with ductile iron and a plasma moly face for added strength and wear resistance.

The plasma moly coating on the top ring is a notable feature, helping to reduce friction and improve sealing against the cylinder wall. This construction aims for better performance and longevity, especially in demanding engine conditions. The ductile iron material provides a solid foundation, balancing strength with the ability to handle the stresses within the cylinder. These are designed as high-tension rings, meaning they exert more pressure against the cylinder wall to ensure a tight seal.

When rebuilding your engine, choosing reliable components like these Mahle piston rings is important for overall engine health. Ensure you consult your vehicle's service manual for proper installation procedures and any specific ring gap recommendations for your application.
