What is the advantage of nitride steel piston rings?

Nitride steel piston rings have a hardened surface due to the nitride treatment. This makes them more resistant to wear and heat, which is beneficial for performance engines and helps ensure a good seal against the cylinder wall.

What does 'bulk pack of 48' mean for my engine build?

This means the set contains 48 individual piston rings. It's intended for builders or shops that work on multiple engines requiring this specific ring size, offering a more economical option than purchasing individual sets.

Are these rings suitable for all types of gasoline engines?

These rings are specifically noted as 'Performance Gas' and feature nitride steel construction, making them well-suited for performance gasoline applications. However, always confirm compatibility with your specific engine's requirements and refer to the service manual for proper installation.

Product Details

This is a bulk pack of 48 Mahle OE Performance Gas Nitride Steel Piston Rings, designed for a 4.105-inch bore. These rings feature a nitride steel construction, known for its durability and resistance to wear, making them a solid choice for engine rebuilds where performance and longevity are key. The specific dimensions, including a 0.043-inch thickness and a 0.157-inch second land width, are crucial for proper sealing and oil control within the cylinder.

Mahle's nitride treatment on these rings raises their surface hardness, which helps them withstand the high temperatures and pressures found in performance gasoline engines. This treatment also improves their compatibility with various cylinder wall finishes and lubricants, contributing to a well-sealed combustion chamber and reduced oil consumption. Because this is a bulk pack of 48 rings, it's ideal for shops or builders who frequently work on engines requiring this specific ring size, offering a cost-effective solution for multiple projects. Ensure you are not shipping to California, as these rings are not CARB approved.

When rebuilding an engine, selecting the correct piston rings is critical for performance, oil control, and engine life. These Mahle rings are well-made and designed to meet the demands of performance applications. Always refer to your specific engine's service manual for proper installation procedures and ring gap specifications to ensure optimal performance and durability.
