What is the nitride finish on these piston rings?

The nitride finish is a surface treatment applied to the steel rings. It creates a hard, wear-resistant layer that helps the rings stand up better to friction and heat inside the cylinder, promoting longer life and consistent sealing.

What does 'bulk pack' mean for this product?

This product is a bulk pack containing 48 individual piston ring sets. It's intended for engine builders or shops that require a large quantity of rings for multiple engine builds or projects.

Are these rings suitable for all engine types?

These rings are specifically designed for performance gasoline engine applications and are made from steel with a nitride finish. It's important to verify that the 4.060 inch bore size and other dimensions match your specific engine's requirements.

Product Details

If you're rebuilding the engine in a performance gasoline application, getting the piston rings right is crucial for sealing and power. This bulk pack of Mahle OE piston rings is designed for those situations where you need multiple sets for a project or for a shop that does a lot of engine work. Each ring is made from steel with a nitride finish, which helps with durability and wear resistance in demanding conditions.

These rings are built to a 4.060 inch bore size with a 0.043 inch ring thickness and a 0.157 inch oil ring width. The nitride treatment on the steel surface provides a hard, wear-resistant layer that holds up well against friction and heat, helping to maintain a good seal between the piston and cylinder wall over time. This is important for both power output and oil control. Because this is a bulk pack containing 48 sets, it's a practical choice for engine builders who need a consistent supply of reliable components for multiple builds.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Ensure you check your specific engine build requirements to confirm these dimensions are correct for your application.
