The bad thing is that I don't believe that ford has a part number for a 2011+ truck with 3.73's unless it has a Dana 80.

May have to go aftermarket.

Do you really think thats gonna be needed? You already know this but its already a big jump from the 331s to the 373s and the way the powerband is on these trucks I would think that would suffice?.. unless your going to a bigger tire then you already stated? Thoughts on wanting 410s?

That sucks. I was hoping I could find ones is it possible to just lose the locker and put 4.10's in? I'm not going to be happy with 3.73's and 35's

MorganM · Mar 6, 2014

I don't care for the e-locker- are you guys wanting to keep it? If so, what am I missing that makes it better than a truetrac?

so far 3:73 is waaayyy better. no more downshifting. gained about 300 rpm .. this truck needed that so badly.

Nice, glad to hear you were able to get them and they helped up top. I am sure the acceleration improved some too.

i havent left real hard yet, but the early gears at wot are substantially stronger, seems to be sitting at 3000+ rpm thru each shift. i think the difference in power there is substantial, just need to run it down the track and see.

Nice

Good. I do think 3.73's are as far as I'd go with 35's. I really don't know that id change from 3.55's that I have now. It pulls good and spools well. And it cruises at 80 very nice. But 3.31's would have had to go.

I think if you could get the shifting down right 4.10's would be great. It just helps that much more to me once you have them and I could still pull 16.5-17.5 on the highway running empty. It definitely takes away from top end power. But man it really helps pulling my camper. If I get to running 35's all the time I hope I can get a 4.10 rear set. And I'll lose the e-locker I really don't need it.

Congrats on the results, very cool

i think for my purpose, the 3:73 will stay unless i go to a much laggier turbo setup, which will never happen. i'm prolly gonna try the 67.7 FMW from HTT , i'd like a bigger turbine with a 360* bearing. i'm a little apprehensive of the s300's .. so bigger turbine will be more resilient. that being said, at cruising speeds and maintiaining 1800 rpm at 70-75 , i'm just on the edge of being lit, so no downshifitng whatsoever. my truck was downshifitng all the time with the 3:31 , i guarantee i could tow very effectively with this setup, just not with 2300 pw that im currently running.
