Product Details
This is a Mahle 4.500 inch bore, 1.5mm gas nitrided steel severe duty top ring set. These rings are built to handle demanding conditions, often found in heavy-duty or performance engine builds where extra durability is needed. The gas nitriding process hardens the surface of the steel, making it more resistant to wear and heat.
The 1.5mm thickness is a common size for many performance and heavy-duty applications, offering a good balance of sealing and durability. Mahle is a well-known name in engine components, and these severe duty rings are made to be a strong option when you need your engine to hold up under stress. They are designed to provide a solid seal between the piston and cylinder wall, which is crucial for proper engine performance and longevity.
Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific build requirements and manufacturer recommendations when selecting piston rings.
