Mahle Rings Perf Gas Nitride Steel 4.145in x .043in .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

In this bulk pack, you get 48 sets of Mahle OE performance gas piston rings. These rings are made from steel and feature a nitride coating for improved durability and performance. Each ring measures 4.145 inches in bore diameter with a 0.043-inch thickness and a 0.157-inch ring groove width. This set is designed for gas engines and is a solid option when you're rebuilding or refreshing an engine where top-notch sealing and wear resistance are critical.

The nitride surface treatment on these rings is a notable feature. It hardens the ring surface, which helps them resist wear and scuffing, especially under the higher temperatures and pressures found in performance gas applications. This improved wear resistance means the rings can maintain a good seal against the cylinder wall for longer, contributing to consistent compression and efficient combustion. The steel construction provides a strong foundation for the nitride coating, ensuring these rings can handle demanding use.

This is a bulk pack containing 48 individual ring sets, making it a practical choice for shops or builders working on multiple engines or a large project. When installing, always ensure the cylinder walls are properly honed and clean, and that the ring gaps are set according to the manufacturer's specifications for the specific engine build. Proper installation is key to realizing the full benefits of these well-made piston rings.
