What is the benefit of the HVOF Moly coating on these rings?

The HVOF (High Velocity Oxygen Fuel) Moly coating creates a very dense and wear-resistant surface on the top ring. This helps the ring seat properly against the cylinder wall, improves sealing, and reduces friction for better performance and longevity.

What does the '48 Qty Bulk Pk' mean?

This is a bulk package containing 48 individual piston rings. This quantity is typically suited for professional engine builders or workshops that handle multiple engine builds or larger projects.

Are these rings suitable for all engine builds?

These are performance-oriented steel top rings with a specific bore size (4.060 inches) and coating. While well-built for demanding applications, always confirm they match your specific engine's requirements and the intended use of your build.

Product Details

When you're rebuilding the top end of your engine, getting the piston rings right is crucial for sealing and performance. These Mahle OE performance plasma steel top rings are built for serious engine work, designed to handle the pressures and heat of a performance application. They feature a 4.060-inch bore size, a 1.0mm top ring width, and a 0.143-inch oil ring width, making them suitable for many performance engine builds.

What sets these rings apart is the HVOF (High Velocity Oxygen Fuel) Moly coating on the top ring. This advanced coating process creates a dense, wear-resistant layer that helps the ring seat properly and reduces friction against the cylinder wall. This means better sealing, improved oil control, and longer ring and cylinder life, especially under demanding conditions. The plasma-moly construction offers a well-built and durable solution for your engine's critical sealing components. This is a bulk pack containing 48 rings, ideal for shops or builders working on multiple engines or larger projects.

It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for installation procedures and recommended clearances to ensure a proper rebuild.
