Product Details
This is a Mahle GNS Severe Duty Top Ring Set, measuring 4.440 inches in diameter with a 1.5mm thickness. These rings are made from gas nitrided steel, a tough material chosen for its durability in demanding conditions. They are specifically designed for severe duty applications where engine components face higher stress and heat.
The gas nitriding process hardens the surface of the steel, making these top rings more resistant to wear and scuffing. This improved durability can help maintain a better seal between the piston and cylinder wall, which is crucial for engine performance and longevity, especially in high-stress environments. This set is intended for an 8-cylinder engine application.
