Mahle Rings Performance Napier Steel 2nd Ring 4.100in x 1.0MM .136in RW Plain Ring Set

Mahle OE Piston Rings are a solid option for rebuilding your engine. This set features a Napier-style second ring, which is designed to help scrape oil from the cylinder wall more effectively than a standard ring. The steel construction means these rings are built to last through many heat cycles and miles.

The 4.100 inch bore size is common for many V8 engines, and the 1.0mm top ring groove and .136 inch second ring groove are standard dimensions for many performance applications. Using a Napier hook on the second ring helps break up the oil film on the cylinder wall, improving oil control and reducing blow-by. This can lead to a more efficient burn and better overall engine performance.

When you're rebuilding an engine, getting the piston ring details right is crucial for sealing and oil control. This Mahle set is a well-built choice for many engine builds.
