Cylinder head for Cummins 6CT

The cylinder head 3973403 is a primary component for the Cummins 6CT engine. It mounts to the top of the cylinder block to seal the combustion chambers and contains the intake and exhaust valves, valve springs, guides, and seats. This component is engineered to maintain the structural integrity required for the pressures and temperatures present during engine operation.

This part is compatible with the Cummins 6CT engine model. It is manufactured to meet the specific fitment requirements for this engine configuration, allowing for direct installation and alignment with existing engine systems.

A cylinder head functions as the top cover of the engine block, creating a closed environment for the combustion process. By sealing the cylinders, it allows the engine to maintain the compression necessary for power generation. It also provides the necessary passages for coolant and oil circulation, as well as mounting points for the valve train components that manage the timing of air intake and exhaust gas release.
