Do Gen IV rods have any kind of casting number or marking on them?

I found these but they do not have any castings or markings besides some laser etched or inked numbers. You can see it in the first picture.

Can anyone identify these?









Thanks

 

Those are GEN 4 rods.

Here is a side by side of the much smaller GEN 3's.

 

Thanks man, I appreciate the quick response.

So, they do not have any casting numbers or markings on them?
Did they ever have any casting marks?

 

Some do and some don't. I could not tell you why that is though.

 

The quick answer is the strong rods are square on both sides.

 

GEN 4 rods will also have the brass bushing in the little end for the floating pin

 

Gotcha

Thanks for the info guys, I appreciate it.
