One New Aftermarket Replacement Single Cylinder Head Gasket Kit for Caterpillar (Cat) 3400 Series Engines
This aftermarket replacement single cylinder head gasket kit covers the gaskets and seals needed to rebuild and reinstall one cylinder head on Caterpillar (Cat) 3400 series diesel engines. Proper cylinder head sealing is critical for maintaining compression, preventing coolant and oil leaks, and protecting the engine from catastrophic damage during heavy-duty operation. Replace this kit whenever performing a top-end rebuild, head removal, or after signs of gasket failure such as coolant loss, overheating, or compression loss.
