So WHY! Ford use boxed frame now ? -http://www.trucktrend.com/news/1509-five-hard-working-features-of-the-2017-ford-f-series-super-duty/

 

I strongly suspect the 2017 Super Duty will compare much more favorably now:

 

Oh yea no doubt there, 23 times stronger says a lot. The frame in these F250's are pretty flimsy really. There are so many long bed trucks that have that resonance at 42mph and get that bounce. My old SCLB had it and it took some work in frame stiffening to get it to stop.
Once these trucks passed 7,000 lbs they should have upgraded the frame. Neighbor has a 2017 and it feels like it's on rails, these new frames are a game changer.

 

Wait a minute. So the 2017 Super Duty frame is 23X stiffer than the previous generation Super Duty, and the Chevy HD frame is 30X stiffer than the previous generation Super Duty? Did I read that right?

What PSI steel does Ford use in the Super Duty frame now? I know the Chevy HD uses 60k and the Ram uses 50k, can't find out what the Ford uses.

 

Not sure but i recall it to be 50.000. Anyways the Ford frame ist bigger general dimensions of the rails:

Cheyv 215x88x4.5mm

Ford 240x89x4.7mm

Since the height of the frame is the most important part, i guess the Ford frame is quite a bit stronger now.

But i wonder when Dodge will follow this? 2018?

 

Back in 2014, Here ya go;

I really don't like this "frame war" that manufacturers are in. I believe these ultra stiff frames are the cause of highway shake/vibrations you hear about on forums (Ram especially)

C-channels also don't hold water, dirt, and mud inside to rust out, and C-channels give us DIY mechanics access to, and a place to run new lines, etc... And yes, frame flex is a good thing.
