Mahle Rings Perf Gas Nitride Steel 4.045 x .043 .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

The nitride steel construction on these Mahle piston rings is a key detail for anyone rebuilding a performance gasoline engine. Nitriding is a heat-treating process that hardens the surface of the steel, making it incredibly resistant to wear and scuffing. This is crucial for maintaining a good seal between the piston and cylinder wall, especially under the higher pressures and temperatures found in performance applications. The rings themselves measure 4.045 inches in bore size, with a top ring thickness of .043 inches and a second ring thickness of .157 inches, designed for optimal sealing and oil control.

This bulk pack contains 48 sets of rings, making it a practical choice for shops that frequently work on performance engines or for engine builders who need a reliable supply of high-performance components. Mahle is a well-known name in engine building, and these rings are built to handle the demands of performance gasoline engines. The precise dimensions and durable nitride finish contribute to improved compression, better oil control, and overall engine efficiency. Proper installation is key to realizing the full benefits of these rings, ensuring a tight seal and long service life.

When rebuilding your engine, choosing the right piston rings is fundamental to its performance and longevity. These Mahle rings offer a well-built solution for performance gasoline applications, providing the durability and sealing performance needed to get the most out of your engine build. Please note that these rings are not CARB approved and cannot be shipped to California.
