Mahle Rings Perf Gas Nitride Steel 4.130in x .043in .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

This is a bulk pack of 48 Mahle OE performance gas piston rings, designed for a 4.130-inch bore. These rings feature a nitride steel construction, measuring 0.043 inches for the top ring and 0.157 inches for the second ring. They are intended for gasoline engines where improved sealing and durability are key.

The nitride treatment on these steel rings helps to increase their hardness and wear resistance, which is crucial for maintaining a good seal between the piston and cylinder wall under high operating temperatures and pressures. This improved sealing directly impacts engine performance by ensuring efficient combustion and reducing oil consumption. The 4.130-inch bore size is common in many performance and heavy-duty V8 applications, making this a solid option for engine rebuilds or performance builds where a large number of cylinders need rings.

This bulk pack is ideal for shops or builders who frequently work on engines requiring this specific ring size and configuration. It ensures you have plenty on hand for multiple projects or for engines with a higher cylinder count. Remember that these rings are not CARB approved and cannot be shipped to California.
