What is the advantage of nitride coating on piston rings?

Nitride coating creates a hard, wear-resistant surface on the piston rings. This helps to reduce friction and wear on both the rings and the cylinder walls, leading to a longer service life for your engine components.

What does 'bulk pack' mean for these piston rings?

A bulk pack means you receive a larger quantity of the product, in this case, 48 individual ring sets. This is often more economical for professional engine builders or those working on multiple engines.

Why are these rings not CARB approved?

Some engine components may not meet specific emissions standards set by regulatory bodies like the California Air Resources Board (CARB). As a result, they cannot be legally sold or shipped to California.

Product Details

Mahle is a well-known name in the automotive industry, particularly for their expertise in engine components. This bulk pack of performance gas piston rings, part number 3011180B, is designed for engine rebuilding projects where precision and durability are key. These rings are made from steel and feature a nitride coating, which helps them resist wear and maintain their sealing properties under demanding conditions.

Each ring in this set has a bore size of 4.095 inches and a thickness of .043 inches, with a .157 inch oil ring width. The nitride surface treatment is a notable feature, as it creates a hard, wear-resistant layer that can extend the life of both the rings and the cylinder walls. This makes them a solid option for performance gas engines where heat and stress are higher than in standard applications. This bulk pack contains 48 individual ring sets, making it suitable for shops or individuals working on multiple engines or a large project.

It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures when rebuilding your engine.
