Mahle Rings Perf Gas Nitride Steel 4.075 x .043 .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

This bulk pack includes 48 sets of Mahle OE Performance Gas Nitride Steel Piston Rings. These rings are designed for a 4.075 inch bore with a .043 inch top ring, .157 inch oil ring, and feature a standard tension ring gap configuration. The nitride steel construction offers improved durability for performance gas engine applications.

Mahle's nitride treatment on these steel rings helps to increase surface hardness, which can lead to better wear resistance and a longer service life, especially in engines that see higher operating temperatures or increased stress. This particular set is intended for use in a 4.075 inch bore, making it suitable for a range of performance engine builds where precise piston ring sealing is critical for optimal power and efficiency. The .043 inch top ring and .157 inch oil ring dimensions are common specifications for many performance gas engines.

Because this is a bulk pack of 48 sets, it's an economical choice for engine builders or shops that frequently work on performance gas engines requiring this specific ring size and type. Please note that these rings are not CARB approved and cannot be shipped to California.
