What is the primary benefit of the nitride surface treatment on these rings?

The nitride surface treatment on the top compression rings is applied to increase hardness and wear resistance. This helps the rings withstand higher operating temperatures and pressures found in performance engines, leading to improved durability and a longer service life.

Are these rings compatible with all piston types?

These rings have a .170 inch width, which is a common size for many performance pistons. However, it's crucial to verify that your specific pistons are designed to accept this ring width and groove depth to ensure a proper fit and seal.

What does '48 Qty Bulk Pk' mean for my purchase?

This means the package contains 48 individual piston rings. This quantity is typically intended for engine builders or shops that are working on multiple engine rebuilds simultaneously, offering a cost-effective solution for high-volume needs.

Product Details

This is a bulk pack of Mahle OE Performance Steel Piston Rings, designed for high-performance gasoline engines. Each ring measures 4.565 inches in bore diameter with a .043 inch thickness, featuring a nitride surface treatment for improved durability and reduced friction. This set includes 48 rings, making it ideal for engine builders or shops working on multiple performance builds. The nitride coating on the top compression ring is a key feature for engines that see demanding use, helping to withstand higher temperatures and pressures while maintaining a good seal.

Mahle has a long history in engine components, and these rings are built with their OE (Original Equipment) standards in mind, adapted for performance applications. The steel construction offers strength and resilience, crucial for maintaining compression and preventing blow-by under stress. The .170 inch ring width is standard for many performance applications, ensuring compatibility with a wide range of pistons. When installing, pay close attention to ring gap specifications, as this is critical for performance and engine longevity, especially with performance builds where clearances can be tighter.

This bulk pack is a practical choice for those rebuilding multiple engines or for professional shops that frequently work on performance gasoline applications. While these rings are built for performance, remember they are not CARB approved and cannot be shipped to California. Always refer to your specific engine build's specifications and manufacturer's recommendations for installation and proper ring gap settings to ensure optimal performance and engine health.
