Subscribed. Will be assembling my block with de-lipped 0.030 OEM slugs.
No cracks in 260,000km on the stockers, but ate a bunch of rings..

Melted. Doesn't really fit the failed category.

Mine made it 140,000 before it cracked a piston. Spartan, KEM, Innovative, Gearhead 2008
Another truck I am working on right now made it 60,000 cracked a piston and now has 10k on International coated pistons and I believe it has a cracked piston again. KEM and H&S 2008
Another truck with 40,000 has to what I think is another cracked piston and this truck is a 2010 H&S tunes

This is the best I could do. 6000 km's. But in reality it was caused by bad casting rather then stress.

What tuning where you running when this happened?

Innovative or Gearhead, it happened while towing so I am assuming gearhead.
I think your pistons almost have to be a fluke. I have been following your builds from the beginning and I can't believe they are still holding. If you ever do replace them, if you can find a batch number, please post it. I would love to see if there are others from the same batch with similar results.
That was definitely an interesting finding.

100k miles on mine a day still fine. Max powers and 110's for awhile and no issues. Job 1 truck too.

So for someone looking at buying a 6.4 ... this thread...is it something to cause pause...or not? Seems like a lot of cracked pistons out there for tuner only trucks.
Is this a deal where it's a 7.3 pmr rods, 6.0 heads, 6.4 pistons...6.7 ?
Serious question. Say a 6.4...deleted, tuner only...otherwise stock...are cracked pistons a inevitable reality with the 6.4

Cracked pistons on these trucks are hit or miss. Some people crack them when stock and others can make 1300hp and daily drive the truck with no problems
