Mahle Rings Gas Nitride Steel Perf Top Comp 4.605in x .043in .170 RW Plain Ring Set (48 Qty Bulk Pk)

Mahle is a well-known name in the automotive industry, often recognized for their OE-quality engine components. This particular set of piston rings, the 3011041B, continues that tradition, offering a bulk pack of 48 sets designed for performance applications. These rings are crafted from steel and feature a nitride treatment on the top compression ring, a process that hardens the surface and improves wear resistance, which is crucial for engines that see a lot of use or are built for higher performance levels.

Each ring in this set measures 4.605 inches in bore diameter and has a thickness of 0.043 inches, with a 0.170 inch ring width. The nitride treatment on the top ring helps it seal effectively against the cylinder wall, even under demanding conditions, contributing to better compression and reduced oil consumption. This bulk pack is ideal for engine builders or shops that frequently work on performance engines or need a consistent supply of high-quality rings for multiple projects. The steel construction offers a solid foundation for reliable sealing and durability.

When installing these rings, ensure you follow the manufacturer's recommended procedures for proper seating and break-in. This set is intended for performance builds where precise sealing and durability are paramount. Please note that this product is not CARB approved and cannot be shipped to California.
