About this part

Product Details

Mahle OE is known for making reliable engine parts, and these Performance Napier Steel 2nd Rings are no different. If you're rebuilding the top end of your engine, these rings are designed to help seal the combustion chamber effectively. The Napier style on the second ring is a common design that helps prevent blow-by and oil consumption.

These rings are made from steel, which offers good durability for everyday driving. The specific dimensions are 4.070 inches in bore size with a 1.0mm thickness for the second ring and a .136 inch depth. This set is a plain ring, meaning it doesn't have any special coatings or treatments beyond the base material.

It's important to 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.
