Mahle Rings 4.0000 Bore Dia Claimer Series Ring Set Moly Top Ring Moly Ring Set

These Mahle Claimer Series piston rings feature a moly top ring and a moly ring set, designed for a 4.0000 inch bore diameter. Molybdenum coatings on piston rings are known for their ability to reduce friction and improve wear resistance, which is crucial for the longevity of your engine's performance. This makes them a solid choice for rebuilds where durability and consistent sealing are key.

The Claimer Series is Mahle's well-known line for standard bore applications, offering a reliable option for many engine builds. The moly coating helps the rings seat properly against the cylinder wall, ensuring a good seal and preventing blow-by, which can rob your engine of power and efficiency. This attention to material and design helps maintain proper oil control and compression.

Please note that these rings are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper fitment and break-in procedures.
