Product Details
This is a Mahle GNS Severe Duty Top Ring Set, measuring 4.375 inches with a 1.5mm profile. These rings are designed for engines that face tough operating conditions, often referred to as severe duty. The gas nitriding process hardens the steel surface, making it more resistant to wear and heat, which is crucial for maintaining a good seal between the piston and cylinder wall under stress.
The 1.5mm thickness is a common size for many performance or heavy-duty applications where a strong seal is paramount. Gas nitriding is a surface treatment that introduces nitrogen into the steel, creating a very hard and durable layer. This helps the rings stand up to higher combustion pressures and temperatures, reducing the risk of premature wear or failure. This set is intended for an 8-cylinder engine.
Please note that this part is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
