Mahle Rings Perf Napier Steel 2nd Ring 4.085in x 1.0MM .136in RW Plain Ring Set (48 Qty Bulk Pack)

Mahle OE is a well-known name in the engine parts world, often supplying parts straight from the factory. This bulk pack of 48 performance Napier steel 2nd rings is designed for a 4.085-inch bore. The 1.0mm thickness and .136-inch width are specific dimensions for certain engine builds where precise ring sealing is critical.

These rings feature a Napier hook design on the second ring, which helps improve oil control and prevent blow-by by creating a more effective seal against the cylinder wall. The steel construction offers good durability and performance under demanding conditions. This set is intended for engine builders or shops that need a quantity of these specific rings for multiple projects or a large rebuild.
