which rings for 2005 6.0 with floating rods
so I'm trying to get all my ducks in a row to fix my hurt motor (went lean on the rev limiter at ~15psi)
i am seeing there are two different stock ring sizes for 6.0's
gen 3's got a 1.5 - 1.5 - 3.0 (mm)
and true gen 4's got a 1.2 - 1.5 - 2.5 ???
without a piston in my hand to measure, can I say for sure which ring pack I need?
also I'd like to try a napier type second ring. are these available in 4.000 bore?

If not, I would suggest either Mahle 41858CP if you have the 1.5/1.5/3.0 rings or 42084CP if you have the 1.2/1.5/2.5 rings. You should be able to find them for ~$50 and they have a Napier second ring.

yes NPR is nippon piston ring co
looking though their pdf catalog is confusing as all hell
no idea what rings the 4" 1.5 1.5 3.0 set they list has in it or who carries them.
probably go with the mahle/PC KCS suggested

I agree with this. Make sure the cylinders don't need to be honed or bored out to repair before buying rings.

Is that an offer?
No problem, happy to help. How does the cylinder walls look?

I found a set of NPR's for the GM 4.000" bore 1.5-1.5-3.0mm ring pack but they are traditional style 2nd ring and a moly faced top ring.
they have a napier 2nd ring set for the 1.2 1.2 2.5 ring pack and another non stock application listed with the 1.5 1.5 3.0 pack for a 4.000" bore but it has a smaller ring ID than stock...which I assume is for a custom piston.
KCS, the bore appears fine, my plan was to run a ball hone through it and slap another piston in it.
but it looks like plans have changed a little
