What is the advantage of a nitride finish on piston rings?

A nitride finish is a surface treatment that hardens the ring. This makes it more resistant to wear and can improve its longevity, especially under demanding engine conditions.

Why are these rings sold in a bulk pack of 48?

This bulk pack is intended for professional engine builders or shops that frequently work on multiple engines. It ensures you have enough rings on hand for several builds without needing to order smaller quantities repeatedly.

Are these piston rings suitable for all engine types?

These rings are specifically designed for gasoline engines. They are not suitable for diesel engines or other specialized applications. Always confirm your engine's requirements before purchasing.

Product Details

If you're rebuilding an engine and need a bulk supply of high-performance piston rings, this Mahle OE set is a solid choice. These rings are built for gasoline engines and feature a nitride finish, which is known for its hardness and wear resistance. The 4.110-inch bore size is specific, so make sure it matches your pistons. This particular set comes in a bulk pack of 48, making it ideal for shops that handle multiple engine builds or for larger projects.

Mahle has a long history in engine components, and these rings reflect that experience. The steel construction offers good durability, and the nitride treatment helps them hold up under the stresses of combustion. The ring dimensions are a standard .043 inch for the top ring, .157 inch for the second ring, and the oil ring is also specified for a good seal. Having a large quantity like this means you won't be caught short during a complex rebuild. It’s important to note that these rings are not CARB approved and cannot be shipped to California.
