What is the benefit of a Moly coating on piston rings?

Molybdenum (moly) coatings on piston rings are known for their ability to reduce friction and wear. This is particularly beneficial during the engine break-in period, helping to ensure a good seal and extend the life of the rings and cylinder walls.

What does 'Claimer' mean in the context of these piston rings?

The 'Claimer' designation typically refers to a specific ring design that is optimized for certain performance characteristics. In this case, combined with the moly coating, it suggests a ring built for reliable sealing and durability.

Can these rings be shipped to California?

No, these piston rings are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

These Mahle Moly Claimer top compression rings are built to a 3.7500-inch bore size with a 5/64-inch ring width. Molybdenum (moly) coatings are known for their ability to reduce friction and wear, especially during the critical break-in period, helping to ensure a solid seal and long life for your engine's pistons.

Mahle OE rings are a popular choice for engine rebuilds because they meet the original equipment specifications for fit and function. This means you can expect them to perform reliably and integrate smoothly with your pistons and cylinder walls. The 'Claimer' designation often refers to a ring design optimized for specific performance characteristics, and the moly coating is a key part of that, helping to maintain a good seal under various operating conditions.

When rebuilding an engine, using well-made piston rings like these is crucial for proper cylinder sealing, oil control, and overall engine performance. Ensure you follow the manufacturer's installation instructions carefully for the best results.
