Mahle Rings Perf Gas Nitride Steel 4.050 x .043 .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

These Mahle OE performance gas piston rings are made from nitride steel, a material chosen for its ability to withstand the heat and stress of combustion. The rings measure 4.050 inches in bore size with a 0.043-inch thickness, designed to create a solid seal between the piston and cylinder wall. This specific set comes in a bulk pack of 48, making it a practical choice for shops or builders working on multiple engines or a large project.

The nitride treatment on these steel rings is a key feature. It hardens the surface, which helps them resist wear and maintain their sealing properties over time, even under demanding conditions. This attention to material and surface treatment means you can expect a well-built component that contributes to efficient engine operation and longevity. They are designed to fit right and perform reliably in gas engines.
