About this part

Product Details

This set includes the top piston rings you need for an engine rebuild. Specifically, you get 1.5mm gas nitrided steel (GNS) severe duty top ring sets, designed for an 8-cylinder engine.

These rings are built for tough conditions. The gas nitriding process hardens the surface of the steel, making it more resistant to wear and heat. This is important for engines that see heavy use or operate under demanding circumstances, helping to ensure a solid seal between the piston and cylinder wall for better compression and oil control.

Please note that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual for proper installation procedures and specifications.
