The Cometic 98-02 Cummins 5.9L 24V Diesel .065 inch MLX 4.100 inch Head Gasket - C5855-065 is a precision-engineered head gasket with a 4.100" bore and .065" compressed thickness.
The Cometic MLX Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short.
