2017 6.7 Rod Differences Found

[GotStroke]

I was looking on fordparts.com and there is a difference in pistons, rods, piston pins and crankshaft in build date after 2016-01-06. There is a 34mm and 35mm piston pin too. That could confirm my theory that some '16s have the upgraded rods and that all '17s have them...

I think until we can get an actual Ford engine build dates with the bigger rods, not just larger wrist pins, its a lot of speculation and misinformation that goes on. That is until more people start actually building these new engines and/or removing the oil pan and visually inspecting what your engine has.

My understanding is they upgraded the wrist pin on the above date. Now they have upgraded the beam from the one on the right to the one on the left..

17 up have better rods. end of story.

Just looking to clarify whether there was one or two changes to the connecting rods between 2015MY and 2018MY.

Wristpin update was in 2016.

Rod update was in 2017.

Call out on the short block with bigger rods is HC3Z, which H = 17MY. End of story.

I have never seen a 16, even a summer build of 2016 have the bigger rod.

Just speaking from experience

Jared to the rescue!!! :ford: Did you ever figure out why the new engines you were getting in from Ford were still getting the small rod design? Cause originally I thought even the new 17 assemblies you mentioned you were getting in were coming with old rod design.

Build dates: Before 1/6/17-34mm pin, After 1/7/17-35mm pin.

Its interesting how pricing for the 15-16 rods are $115.00 a piece and the 17up are $37.00 ?????
