Product Details
This product is a set of Mahle GNS Severe Duty Top Piston Rings. You get the top rings, designed for 8-cylinder engines, with a 1.5mm thickness and a gas nitrided steel construction. These rings are built for demanding conditions.
The gas nitriding process hardens the steel surface, making these rings more resistant to wear and heat, which is crucial for engines that see heavy use or operate under high stress. The 1.5mm thickness is a common specification for performance or heavy-duty applications, offering a good balance of sealing and durability.
Please note that this ring set is not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for installation procedures and recommended ring gap settings.
