anybody got any pix of the ecoboost axle and the axle code? I want to know how much heavier it is than the old axles? Is ring gear still 9.75" or now larger?

Thanks for the pix. What is the code on the axle?

EcoBoost

S935L production date 1-11 door sticker axle type H9

I believe this is the F2 axle update.I read somewhere ford updated the axles on the eco due to breaking pinions

B6 for me. 157" wheelbase. Eco-boost.1/11 build date. 3.73 ls.

Flabioso

They have the same rear ends. The eco-bust is not there stongest motor.

You don't have a clue as to what you are talking about.

The Ford engineer confirmed that the axle had been upgraded because the ecoboost kept breaking them. A guy that works at the Sterling axle plant said that they were "nearly as heavy as a SD axle". I am trying to see if they increased the ring gear size from 9.75" or what changes they made.

A H9 and B6 that someone posted to have on there Eco-bust are the same size as on the 2010 just going by the codes and if they upgraded the axles they problably just made the axles shafts a little thinker but it's still a 9.75... no need for lol...

If I remember the article correctly, all 9.75 axles get the upgrade. The eco-boosts weren't going to be build untill that axle was available. What the upgrade consists of for sure I don't know. I've heard stronger pinions to stronger axles. I'll see if I can link the article tomorrow.
So yes the newer rear ends/axles are stronger than the previous version Flabioso. Try driving one and maybe you won't be so bitter.
