One New Aftermarket Replacement Cylinder Head Gasket for Caterpillar (Cat) 3406 Series Engines
This aftermarket replacement cylinder head gasket (2W8128 / 2W-8128) fits the Caterpillar 3406, 3406B, and 3406C inline six-cylinder diesel engines. The head gasket seals combustion chambers and coolant passages between the cylinder head and engine block, maintaining compression pressure and preventing coolant or oil intrusion into the combustion chamber. It is a critical component during top-end rebuilds, cylinder head replacements, and overheating repairs on Cat 3406 series equipment.
