MAHLE is a globally recognized OEM supplier known for precision-engineered piston rings that meet the strictest tolerances. The gas nitriding process creates an extremely hard surface layer that resists scuffing and reduces friction, making these rings ideal for performance street engines, racing applications, and high-compression rebuilds. Each ring is manufactured to exacting specifications to ensure proper end gap, radial wall thickness, and tension characteristics.

Note: This is a bulk ring set for one cylinder. Order the appropriate quantity for your complete engine rebuild. Proper ring gap checking and fitting is required during installation.
