Mahle Rings Perf Napier Steel 2nd Ring 4.155in x 1.0MM .136in RW Plain Ring Set (48 Qty Bulk Pack)

When you're rebuilding an engine, especially for performance applications, the piston rings are critical for sealing the combustion chamber and managing oil. This set from Mahle OE features their Napier-style second rings, known for their ability to reduce blow-by and improve oil control. The Napier design has a unique tapered face that helps it 'dig in' to the cylinder wall, creating a better seal under pressure.

This is a bulk pack containing 48 rings, making it a solid option for shops or builders working on multiple engines or those who need spares. The rings are made from steel and measure 4.155 inches in diameter with a 1.0mm thickness and a 0.136-inch groove width. Mahle OE is a well-known name in engine components, and these rings are built to perform in demanding conditions, helping to ensure your engine runs efficiently and powerfully.
