Mahle Rings Perf Gas Nitride Steel 4.065 x .043 .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

Mahle is a well-known name in the automotive industry, especially for their engine components. This bulk pack of performance gas piston rings, part number 3011174B, is designed for serious engine builds where precision and durability are key. These rings are made from steel and feature a nitride coating, which is a surface treatment that hardens the metal and improves wear resistance. This makes them a solid choice for engines that will see regular use or higher performance demands.

Each ring in this set has a bore size of 4.065 inches, with a thickness of .043 inches for the top ring and .157 inches for the second ring. The nitride coating helps them maintain their shape and seal effectively under heat and pressure, which is crucial for good compression and oil control. This particular set comes in a bulk pack of 48 rings, making it ideal for shops or builders who work on multiple engines or are rebuilding a V8 or V10 engine that requires more than one set. They are designed for gas engines and are a plain ring set, meaning they don't have special coatings or designs beyond the nitride treatment.

When you're putting together a performance engine, the piston rings are a critical component that directly impacts how well the engine breathes and seals. These Mahle rings offer a well-built option with a focus on wear resistance thanks to their nitride finish. It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper ring gap setting and installation procedures to ensure optimal performance and longevity for your engine build.
