Product Details
This product includes a set of top piston rings, specifically designed for an 8-cylinder engine. These are 1.5mm Gas Nitrided Steel (GNS) Severe Duty rings, meaning they're built to handle tougher operating conditions than standard rings.
The GNS treatment on these steel rings offers improved durability and wear resistance, which is crucial for engines that see heavy use or operate in demanding environments. The 1.5mm thickness is a common size for many performance and heavy-duty applications, providing a solid seal between the piston and cylinder wall to maintain compression and control oil consumption.
Please note that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for proper installation procedures and ring gap specifications.
