Description

The Mahle OE 4.030-inch bore plasma moly ductile engine ring set is engineered for high-performance automotive applications. Designed with precision, these rings feature a 1/16-inch (0.0625-inch) width and a 3.00mm moly coating, ensuring durability and efficient sealing under demanding engine conditions.

Constructed from high-quality ductile iron, these rings provide excellent wear resistance and thermal stability, making them suitable for a range of engine rebuilds and repairs.

Each set includes all necessary rings to complete your engine rebuild, ensuring a proper seal and optimal compression. These rings are not CARB-approved but are suitable for applications where compliance is not a primary concern. Easy to install and designed for long-term reliability, the Mahle OE 4.030-inch bore plasma moly ductile engine ring set is an excellent choice for professional mechanics and serious DIY enthusiasts alike.
