How well are the drive trains in these things holding up? Looking at getting a 2015+ 5.0 4x4 and throwing some power at it, but would hate to be popping axles with the first time I get into it.

I'm sure its been asked before, but I just couldnt find anything searching around. Thanks in advance!

 

Seems to me the drive train is pretty robust. Otherwise, you would be hearing about various issues on this forum, and there just doesn't seem to be much/any.

 

There are lots of tuned EcoBoost trucks throwing down over 600 ft-lbs of torque. That's diesel territory, and you don't often hear of them breaking. I think they hold up pretty well, but I've never been one for engine mods.

 

Of all the things people like to complain about on the internet, I honestly haven't hear of anyone who is unhappy with the transmission, driveshaft or axles from a strength standpoint.
Only thing some folks whine about is hard shifting, but that seems to be pretty rare, and only in certain situations.

That being said, if you are looking at off-road situations, it's easy to snap axles even without more power, just ask the jeep crowd. For on-road use I can't see it being a big concern if you have street tires.

 

Yea, which is why I was wondering how they held up. I know they'd snap like toothpicks behind a diesel!

I figured the trans was doing pretty well, but just havent heard much on the t-case or axles. I'm thinking more of drag strip with decent tires, 650+ whp.

 

Define your diesel. The 3.5L EB pulls like a diesel, with a torque curve to match.

 

Vmp has a ccsb 4x4 5.0 that they're putting 620rwhp down with, and they're running a 11.6 in the 1/4. Sounds pretty stout.

 

A lot of folks are adding Whipple and Roush superchargers, 650+ hp at the crank, close to 550 rwhp, with no drivetrain modification at all.

 

My current diesel play toy makes 1700+ ft/lbs. 11s in the 1/4 @ 73-7400lbs.

That is good to hear, thanks!

 

I installed a Whipple on my 5.0. No issues here. I have not dyno'd it but from what I am told they conservatively dyno at 540 - 560 to the rear. Stock drive train, I do have a level kit and 33's, Gibson dual sport cat back and a K&N airfilter are my only other mod's

 

Cool, thanks for the info!

 

And that is 3.5 liters?

 

You said define my diesel so I did.

The original point is that the axles wouldnt survive in the applications i'm familiar with, thus I turn to you guys for real world information for how they are holding up.

I've got the information I was after, thank you everyone. FTE is great!

 

Well. Sort of. You just gave a power/torque that is roughly 3X what we've been talking about with not a lot more information. I think the original point was regarding the drive line strength in the power range that we're talking about (~~ 400-600 ft-lb torque).

 

I wasnt asking if they would survive with the level of torque i'm around. You are correct about the original point, which is all I've asked.
