Yeah as in split in two if you let it go.

 

It seems to me that the GM pickups also have issues with frame cracking when you put a snowplow on them.

 

Turn the sound off if kids are around or if your get upset over
some very bad language.

I watched that flex video a couple times before I bought my new SD. Didn't have me overly concerned, but had to hand it to Chevy for the stiffness. Good or bad, well I'm not really sure. But with you guys talking about the frames cracking I would say it's bad!! Glad I bought the Ford!!

 

Yes, corrected my post. Thanks.

 

Well, looks like us Ford guys beat this one up, as it has a couple of other time on the site, wonder why that is, now if we wanted to go to the GM site were this video is posted(as I'm sure it is) I would have to guess they are just tearing our SD'S up>>> go figure.

I'll just keep my crappy 6.4 over one of those butt ugly Silvorado's any day.
Did I say crappy, I meant Happy.

 

People with more experience and automotive engineering education would have to say whether having a stiff frame is better for working hard. I'm sure it's better for ride quality and such, but not sure about when loaded down to the hilt as so often happens with these trucks. I also wonder what would happen if you maxed out the load rating on each SRW truck and drove it over that crazy twisting challenge setup 1,000 times. Would everything be the same? Would the Chevy frame crack? Would the Ford frame permanently bend? Or what?

Not exactly a scientific test, just a neat demo if you're a Chevy dealer.

 

Chevy can boast all they want in this video, fact is their 4x4 system is no better than a toyota

I'll take my solid front axle anyday over a junk bowtie already been there and done that... never again

 

The Chevy frame is stiffer, no doubt. My advice? Keep all for wheels on the ground as much as possible and never volunteer your truck for a chevy comparison commercial.

 

This. It's an obvious weakness of the Ford frame vs the Chevy frame. Does it mean that the Ford frame is worse and the Chevy frame is better? Not really but when you're doing marketing you often leave out real world applications. It's about hype and pointing out your competitions weaknesses and your strengths. Doesn't matter that the test is somewhat absurd it is still a weakness of the Ford frame design. It has little do with over all better or worse in this case.

I'll still take a Ford over a Chevy since I like the whole much better than the part.

 

I know guys.....Its an older thread, but I have to say something.
First law of construction engineering:
If you build something too stiff, it will just break
Think at wings at airplanes, for example....... Imagine they were stiff!!!
Lets talk automotive:
Building a "good" frame for a racecar or sportycar you should dump the whole
frame! Why? Because you can build a stiffer body at less weight than you can build a stiff frame.
Why getting stiff? Because its getting a better controlable handling!
So most street carsbodys are getting from generation to generation stiffer and sturdier. They weigh the half of our trucks and should behave like a gocart on asphalt.
BUT
We drive trucks, not sportcars.
In this section is a "good" frame something flexible....forgiveable.....
You cant build a frame for a truck as stiff that it wont break! It just will getting cracks at those points where the most flex will be. So you need to build a flexible frame right from the scratch without any hotspots which getting to break an crack.
Look here and watch the immense flex of the cabin in comparison to the bed:
I think nobody has ever heard about broken Unimog-Frames, right?
.....and nobody would say that theres something better for moving heavyloads over heavy terrain in this weight class, right?
I drove those Mules during my Duty very often and they are virtually undestructable. If you want to move bigger or heavierloads you have to take
a MAN KAT1 8x8. Its the same as a Unimog and at least so flexible, too,
.....just a way bigger and even more badass

 

Well said. And an impressive video!

 

If you look closely the chevy dually is 2wd and the ford is 4wd, solid axle vs IFS, the 3/4 tons were both 4x4 but once again solid axle vs IFS, the dually will much more twist, if the Ford dually was 2wd like the chevy there would not be much of a difference if any, the Fords also weigh more than the chevy.

I just went from an 06 2500 Duramax to an 09 f350 super duty v10 and the Ford is much more of a truck, my buddy who drives nothing but Chevys rode in my truck today and loved it and was blown away I had electronic shift on the fly AND manually locking hubs, he has spent fortunes fixing his Chevies, I got out of mine at 89k as the turbo was failing and no warranty left and the rest of the truck falling apart. I can say the Duramax LBZ/ Allison 6 spd combo is awesome but Ford trucks are so much better in build quality and longivety.

 

That video means nothing. It's just physics 101 and swearing 101. It's no test of anything but it was amazing to see. A battleship can break in half if a meteor hit it, so what? Weak battleship? no; strong meteor.

 

I'm so sick of this " rigid frame" marketing BS

A rigid frame on a pickup truck is a solution to a nonexistent problem. Truck frames have been flexing and rebounding since the invention of the powered wagon over 100 years ago. The only purpose a more rigid frame serves is to make a truck handle a little more like a Toyota corolla for the urbanites and soccer moms who seem to be disappointed by a truck riding and handling like a truck.
