Pentastar Block Guard Set 3.6L

Description

Open Deck? What is an open deck? The Pentastar engine has an “open” deck and not a “closed” deck. This is a reference to whether or not the engine block is open at the top area surrounding the cylinder sleeves or if it is closed. The top of the cylinder is where the greatest amount of stress and pressure exists because this is where the combustion process takes place. As you increase the cylinder pressure with forced induction you increase the stress and stability of the cylinders themselves. Extreme levels of Supercharging or Turbocharging without stabilizing the cylinder can cause the cylinder to become unsteady and actually shift and fail completely.
