Cylinder Heads

Diesel cylinder heads are available for a variety of engine applications including engines from the C-Series. In order to ensure the quality of our castings, our cylinder heads are CNC machined using premium materials and cutting-edge manufacturing.

In addition, Cylinder Heads are available as bare Cylinder Heads that can be swapped with re-usable parts from the original cylinder head at a fraction of the cost. Along with the bare cylinder heads, we also offer a complete inventory of new replacement valvetrain parts.
