Product Details
Mahle is known for making well-built engine components, and this steel Napier ring set is no exception. If you're rebuilding an engine and need reliable piston rings, this set is designed to help your pistons seal properly in the cylinder bore. The Napier hook design on the second ring helps to scrape oil down the cylinder wall, which can improve oil control and reduce blow-by.
This particular set is for a 4.630 inch bore and features a 1.0mm top ring thickness with a .136 inch ring width. The steel construction offers good durability for many engine applications. It's important to note that these rings are not CARB approved and cannot be shipped to California.
