frame flex with anti sway bar

Anybody remember Pixar's Cars movie from a few years back? The end of the movie had a brief snip of urban SUVs having to suck it up and get dirty off-road. There is a lot of truth in that comic.

There are some trucks (and their SUV counterparts) which may only see 4x4 a couple times in their lives when they drive on to the field to pick up the balls after soccer practice, There are a lot of other trucks that will spend their entire lives 'working'.

Crossing a ditch at an angle with a load in the bed? You betcha, that is real life for a work truck! So I'll amend your statement...

Yes, 99% of urban trucks & SUVs that have 24 inch chrome rims with spinner hubcaps will never be in the situation that test simulates. Work trucks with dirty steel wheels, out getting the job done, will see that often enough on job sites that it is a very real concern.

Am I going to come out and bash a brand based on a YouTube video? Naw. Marketing can employ tricks to get their point across and I don't trust most stuff like this. However, it is interesting how that video showed Dodge vs. Ford. When I watched it on YouTube, the next video up showed the same test with Chevy vs. Ford. I don't think Chevy & Dodge both got together and said let's fake some anti-Ford tests, so there might be some truth there after all.

I added the modern equivalent to my '07 since the roads are so bad in the area. It helps a bunch. A relatively minor change for big impact. http://www.americanmuscle.com/sr-strutbrace-0509-gtv6.html

70's muscle cars with unibody? Camero, Nova, many ran aftermarket sub frame connectors to tie the front and back 1/2's of the uni body together.

Sure the unibody works well when used within the limits it was designed for, but the power gains the aftermarket was finding in the 70s's exceeded these limits I suppose. :)

mkirsch, I am disappointed in your most recent post. Lots of valid questions. This is a discussion forum.

I'm not sure if your post should be taken as "nonsense ", Flaming or a troll.

Does an rear anti sway bar add to or reduce __ frame --- flex ???

Not in any way that matters.

I think that is the correct answer.

Thank you.

All this nonsense about frame flex and whatnot, when 99%+ of trucks will NEVER be in a situation where the frame could even have an opportunity to flex (significantly) is... nonsense!

Ya run yer truck up on 3 ramps, ya deserve what ya get.

Ya go rock bouncin', ya deserve what ya get.

The 2015 Ford F-150 saved about 700# by going to aluminum. It has been reported that the Super Duty 2017 models with aluminum bodies will only save about 350# because the remaining weight will be added to box the truck frame. ...

This made me think of my '04 Dodge 3500 which has a bumper to bumper box frame. I think Dodge saved weigh by making the body out of exceptionally thin steel. You can lean against a front fender and dent it.

You can soften the springs to keep the frame from flexing. It's really a nonsensical ad to show the Ford frame flexing, but at least it's floor is flat. Take that GM owners. ;)

Seriously though, the system is made up of multiple parts, so change one and you have to adjust something else. If you follow motocross, you'll know that any time they modify the frames, they have to make other suspension changes and relative to a truck, those suspensions have a lot less parts.

The 2015 Ford F-150 saved about 700# by going to aluminum. It has been reported that the Super Duty 2017 models with aluminum bodies will only save about 350# because the remaining weight will be added to box the truck frame. It appears that Ford is going to stiffen the frames on their aluminum bodied Super Duty trucks. The cab and chassis version will still be "C" channel under the bed so that it is easy to attach after market beds.
There is nothing wrong with "C" channel frames, but they won't resist twisting as much. Semi Trucks still use "C" channel frames.
