The 6.4 Powerstroke (2008-10 model years) has a notorious problem with the pistons cracking. This issue occurs more frequently in performance applications. The solution for a high performance street driven truck is to install pistons from the International Maxx Force 7 engine. The Maxx Force 7 is essentially the 6.4 Powerstroke but used in International truck applications. When International released the 2011 Maxx Force 7, they designed the pistons for increased performance and they are perfect for use in Ford trucks. The piston design includes a wider combustion bowl that prevents cracking.
These pistons are a direct replacement with the only major change being the compression ratio will lower approximately 0.5. This lower compression has yet to show any negative affects, even in high altitudes and cold temperatures.
Please choose from the available options when ordering.
Bore Size: Std, 0.010" over, 0.020" over, 0.030" over.
Piston Deck Machining: We can remove 0.010" off the deck of the piston in case you have decked your engine block head surface. This option adds $75.00
Thermal Barrier Coating: This coating is designed to produce horsepower by reflecting the combustion heat, instead of absorbing it, and using that heat to drive the piston down but a secondary benefit that helps diesel users is that the coating protects the aluminum from melting when exposed to high combustion temperatures which are common in performance diesel engines. This option adds $345.00
Zero-Gap 2nd Ring: By using a zero-gap 2nd ring, less combustion pressure escapes into the crankcase. We use the zero-gap 2nd ring in all of our engine builds.
