About this part

Product Details

This Mahle OE Piston Ring Set includes the necessary rings for one piston, featuring steel Napier rings designed for improved oil control. The set is sized for a 4.010 inch bore and has a ring thickness of .043 inches, with a specific .135 inch ring width.

These rings are a well-built option for engine rebuilds where reliable performance is key. The Napier hook design on the second ring helps to scrape oil from the cylinder wall, preventing it from entering the combustion chamber and reducing oil consumption. This updated design contributes to better sealing and overall engine health.
