Mahle Rings Perf Gas Nitride Steel 4.200in x .043in .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

If you're rebuilding the engine in a performance application, Mahle's 3011201B piston ring set is a solid choice. These rings are built for a 4.200 inch bore and feature a steel construction with a nitride finish, which helps them hold up under demanding conditions. The .043 inch top ring and .157 inch oil ring provide a good seal for improved performance.

Mahle is a well-known name in engine components, and these rings are made to meet their performance standards. The nitride finish on the top ring is particularly notable because it adds a layer of hardness that resists wear and helps maintain a tight seal against the cylinder wall, even with increased heat and pressure. This is crucial for getting the most out of your engine rebuild, ensuring good compression and efficient combustion. This bulk pack contains 48 sets, making it ideal for shops or builders working on multiple engines.

When installing these rings, always refer to the manufacturer's specific instructions for your engine application to ensure proper gap setting and seating. Proper installation is key to achieving the performance and longevity these Mahle rings are designed for.
