Front End Suspension - No springs??
#11
Mind you they used t-bars in the rear because they were stronger and resisted the roll of the rear axel under the emense power of some of these cars. Even to this day you find people converting from rear springs to torsion bars in alot of muscle cars.
Basically a torsion bar is a metal bar that returns to form after being flexed. In fact a spring is a form of torsion bar, Just the ones in are trucks take different shape. instead of a coil, they are generally straight.
If you want to see a really good example of a torsion bar, Look at those flex frames on eye glasses and imagine that scaled up a bit.

On a side note, I thought I read somewhere the other day that there was going to be a factory option for airbag suspension on 2010 1500's. anyone heard anything about that?

Not 100% true. There are also 3 and 4 links used with solid axles. Usually for major rock crawling such as the XRRA.

Okay, can someone, please show me a 4-link ifs setup? To run a four link you'd be running a solid axle and a solid axle can NEVER be referred to as IFS. Let look into this some more, the "i" in IFS refers to independent, ie; the passenger side tire moves up and down "independently" from the the drivers side with either "A" arms or trailing arms, each side is "independent" front the other. I've never seen, heard of, or can imagine someone connecting a four link to an "A" arm or trailing arms. Now with a four linked solid front axle if I moved said passenger tire up compressing it the drivers side tire is going to roll onto the outside tread shoulder, which is not independent, what I do to one side effects the other in some way. Almost all the trophy trucks I've seen are running long a$$ front A arms and a long travel swing arm in the rear. And as far as car shows go, I've been to enough to know what ladder bars are, I can also tell you what a suicide daygo'd front suspension is. Hope I'm not going on a tangent, but I think there are a few misconceptions suspension systems in this thread.

You know, I was thinking the same thing but I dont know too much about trophy trucks and the hardcore ifs setups they use so I didnt say anything about it.

almost all consumer trucks these days come equiped with anti-sway bars in the front, be it a SFA or IFS therefore you cant say an IFS front end is a true IFS because as one side compresses the other side does the same in order to keep the truck relatively level in turns. This hinders the ability for both sides to travel in a true independent fashion, even when goin over the small stuff like expansion joints or speedbumps. But, take your sway bar off and you'll notice a HUGE improvement in the ride especially when goin over the bigger stuff...at the expense of stability of course.
So when you think about it, todays IFS's reacts quite similar to solid front ends in terms of bump absorbtion all because of this neat invention called the anti-sway bar!

Good post, and i agree 99% but...
