Mahle Rings Perf Gas Nitride Steel 4.150in x .043in .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

Mahle is a well-known name in engine components, often supplying parts directly to automakers. This bulk pack of performance gas nitride steel piston rings, part number 3011191B, is designed for engines with a 4.150-inch bore. These rings feature a .043-inch thickness and a .157-inch ring groove width, suitable for many performance gas applications.

The nitride steel construction offers improved durability and wear resistance compared to standard cast iron rings, which is crucial for engines that see higher operating temperatures and pressures. Nitriding is a surface hardening process that creates a tough outer layer, helping the rings maintain their sealing ability and resist scuffing over time. This set comes in a bulk pack containing 48 rings, making it ideal for shops or builders working on multiple engines or high-performance builds where precise ring selection is key.

When rebuilding an engine, selecting the right piston rings is critical for proper cylinder sealing, oil control, and overall engine performance. These Mahle rings are a solid option for those looking for a well-built component for their performance gas engine project. Please note that this part is not CARB approved and cannot be shipped to California.
