What is the purpose of the chrome plating on the oil ring?

The chrome plating on the oil ring is a wear-resistant surface. It helps the ring seat properly against the cylinder wall and extends the life of both the ring and the cylinder.

What does 'standard tension' mean for these piston rings?

Standard tension rings are designed to provide a good balance between sealing the combustion chamber and minimizing friction. They are a common choice for many engine rebuilds where extreme performance isn't the primary goal.

Are these piston rings CARB approved?

No, these piston rings are not CARB approved and cannot be shipped to California.

Product Details

Starting with a 4.0800-inch bore diameter and a 3/16-inch edge width, this Mahle OE piston ring set is built for standard tension applications. The CP20 oil ring features a chrome surface, which is a solid choice for wear resistance and helps maintain a good seal against the cylinder wall over time. These rings are designed to work with your engine's pistons to create a tight seal, preventing combustion gases from escaping into the crankcase and oil from entering the combustion chamber. This is crucial for maintaining proper compression and keeping your engine running smoothly.

Mahle is a well-known name in engine components, and this set reflects their focus on reliable parts. The standard tension design is common for many engine rebuilds, offering a good balance of sealing performance and reduced drag. The chrome plating on the oil ring is a practical detail that helps the ring bed in properly and resist wear, especially in engines that see regular use. When you're rebuilding an engine, getting the piston rings right is key to its longevity and performance.
