What is the purpose of the HVOF moly coating on these piston rings?

The High Velocity Oxygen Fuel (HVOF) moly coating on the top ring is designed to reduce friction between the ring and the cylinder wall. This helps to minimize wear, improve engine efficiency, and contribute to a longer lifespan for the rings and the engine.

What does 'plasma-sprayed steel' construction mean for these rings?

Plasma-sprayed steel indicates a robust construction method where steel is applied in a plasma state to form a durable layer. This results in a strong, wear-resistant ring that can handle the high temperatures and pressures found in performance engines.

Can these piston rings be shipped to California?

No, this product is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This bulk pack includes 48 Mahle OE performance plasma steel top piston rings. Each ring measures 3.922 inches in bore diameter, with a 1.0mm thickness and a 0.143-inch groove width. These rings are designed for high-performance applications, featuring a plasma-sprayed steel construction for durability and improved sealing. The HVOF (High Velocity Oxygen Fuel) moly coating on the top ring helps reduce friction and wear, contributing to better engine efficiency and longevity.

Mahle is a well-known name in engine components, and this set reflects their commitment to robust construction. The plasma steel top ring is a strong choice for rebuilding or upgrading an engine where reliable sealing and wear resistance are critical. The moly coating is applied using an advanced HVOF process, which creates a dense, well-bonded layer that can withstand the demanding conditions inside an engine cylinder. This ensures that the rings maintain their sealing properties and resist scuffing, even under high operating temperatures and pressures.

This is a bulk package containing 48 rings, making it suitable for shops or builders working on multiple engines or high-volume projects. When installing these rings, ensure you follow the manufacturer's recommended procedures for proper seating and break-in to achieve optimal performance and durability. Remember that this product is not CARB approved and cannot be shipped to California.
