Can any of you great engine guys tell me what's the difference between these pushrods:

and these:

other than the price. Is this just an upgraded version??

Thanks

I'd say that the more expensive is probably made out of a drawn over mandrel (DOM) steel seamless tube cleaner type steel so that it probably heat-treats to a tougher/stronger strengthed material as well as they are centerless ground on the outside.

And I also figure that the cheaper ones are also probably just DOM steel seamless tube too with no real surface prep, but I may be off here?

I will say this, do NOT buy from that link you posted! Way more money than from Summit or similar.
