Yea, to make a more robust crankshaft. And no where in that article did it mention changing out those hypereutectic pistons.


In the 6.4? The pistons are weak because the ring is so high to meet emissions that they cant take any boost. You're on borrowed time at even 6psi. Hellcat pistons are forged and made by Mahle. Again, its de stroked for a reason. OE engines have to meet a crazy level of abuse - hot lapping in death valley, cold starts and WOT in the arctic. Not changing the oil, using the wrong antifreeze etc
