QSB 6.7 pistons 4955160

Anyone have a set of genuine Cummins QSB 6.7 pistons laying around that could upload or send me a few pictures of the markings on them? Just want to make sure what I purchased are genuine Cummins pistons and not some Chinese knock off junk before I send them out to be coated. Thanks

These are the 6.7 qsb’s I used in my engine. Genuine cummins from enterprise same as above. If you zoom you can make out the stampings.

Can't really zoom in far enough to see the markings I'm after, you dont happen to have them laying around still do you? My wrist pin that came with the ones I ordered are in a package rather than a box, has me wondering even more now. Thanks

My pistons that came straight from mother cummins look identical to the ones pictured above, packaging and all.

Sorry, don’t they’re in the engine now. My wrist pins came in the same box as the piston I believe. The small rectangle box on the far left in the first pic above.

Idk they looked good and looked like OE pistons in the pictures. I was going to buy from them for an extra set.

I'm sure they are fine I'm just second guessing myself because where I work I can order direct from Mahle and a set of equivalents is cheaper.
