Mahle Rings Perf Gas Nitride Steel 4.195in x .043in .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

Mahle OE is known for making solid engine components that perform well, and this bulk pack of performance gas piston rings is no exception. If you're rebuilding an engine and need a set of reliable rings for a 4.195-inch bore, these are a strong option. They're made from steel with a nitride finish, which helps them stand up to the demands of a gas engine.

The key feature here is the nitride surface treatment. This process hardens the ring surface, making it more resistant to wear and reducing friction. This means better sealing against the cylinder wall for improved compression and less oil consumption over time. The rings measure 4.195 inches in bore diameter and have a thickness of 0.043 inches, with a 0.157-inch ring groove width. This bulk pack comes with 48 rings, making it ideal for shops or builders working on multiple engines or larger projects.

When installing these rings, pay close attention to the manufacturer's recommended gap settings for your specific application. Proper gapping is crucial for optimal performance and longevity. Remember, these rings are not CARB approved and cannot be shipped to California.
