Mahle Rings Performance Plasma Steel Top Ring 3.825in x 1.0MM .143in RW HVOF Moly Ring Set

Mahle OE offers these performance plasma steel top piston rings, designed for a 3.825-inch bore. These rings feature a 1.0mm face width and a 0.143-inch wire width, utilizing HVOF Moly coating for improved durability and sealing. They are a well-built component for engine rebuilds where enhanced performance and longevity are key.

The plasma-enhanced steel construction provides a strong and wear-resistant surface, crucial for handling the heat and pressure in performance applications. The HVOF (High-Velocity Oxygen Fuel) Moly coating further aids in reducing friction and wear, helping the rings seat properly and maintain a good seal against the cylinder wall. This attention to material and coating helps ensure consistent compression and efficient oil control.

Please note that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for installation procedures and recommended ring gap settings.
