Mahle Rings Performance Napier Steel 2nd Ring 4.270in x 1.0MM .136in RW Plain Ring Set

Mahle is known for making solid engine components, and this Performance Napier Steel 2nd Ring Set is no exception. If you're rebuilding an engine and need reliable piston rings, this set is built to perform. The Napier hook design on the second ring is a key feature, helping to scrape oil off the cylinder walls more effectively than a standard ring. This improved oil control is crucial for preventing oil from getting into the combustion chamber, which can cause blue smoke and reduce engine efficiency.

These rings are made from steel, offering good durability for performance applications. The 4.270-inch bore size and 1.0mm width are standard for many applications, and the .136-inch ring height ensures it fits correctly in the piston groove. When you're putting an engine back together, using well-made components like these Mahle rings helps ensure a strong seal and long life for your rebuild.
