Mahle Rings Perf Napier Steel 2nd Ring 4.190in x 1.0MM .136in RW Pack Ring Set (48 Qty Bulk Pack)

Starting with a Napier-style second ring design, these Mahle OE piston rings are built for performance applications. The Napier profile helps the ring seal better against the cylinder wall, especially as the piston changes direction, which is crucial for maintaining compression and controlling oil. This bulk pack contains 48 rings, making it a solid option for engine builders working on multiple vehicles or performance builds.

Constructed from durable steel, these rings are designed to withstand the rigors of performance engines. The 4.190-inch bore size and 1.0mm thickness are specific dimensions that ensure a proper fit and seal within the cylinder. The .136-inch ring width is also a key measurement for compatibility with specific piston designs. Mahle OE is a well-known name in engine components, and these rings reflect their commitment to well-built parts for demanding engine work.
