I know its probably a stupid question,
Im building an f150 4 door truck, its gonna weigh 5 to 6k when finished.
Im at the stage in the build when i need to choose the correct torsion / sway bar setup.
What exactly does the sway bar and torsion bar do?
Who sells the best setup? (cost and appearance)
Is it something that i can make at home?
Is there anywhere else I can mount them? (i.e. on the rear end? or do I have to mount them from the back of the chassis?)
What different types of setups are out there?
Thanks,
Carlos

Quick and dirty answer without going overboard. . .it minimizes bodyroll in turns

Who sells the best setup? (cost and appearance)

Depends on who you talk to.

Is it something that i can make at home?

With the right tools and research, yes.

Is there anywhere else I can mount them? (i.e. on the rear end? or do I have to mount them from the back of the chassis?)

Yes, start looking at a bunch of pictures of different trucks & buggies. . .you will see a ton of different ways to mount them.

What's called a Torsion bar is not the same as a sway bar. Torsion bars are the spring that holds the truck up, and are used instead of coil springs. Most 1/2 ton Gm trucks and s-10's use torsion bar springs since about 88 or 90. I dont know when or if ford ever used them.

Sway bars link the left and right wheels together through a bar to limit body roll. Body roll is also called sway. Sway bars are in fact a torsion spring, but it is not what is known as a torsion bar. Is that clear??

Speedway engineering has a good selection of sway bars, along with design info.

For what its worth, I went to a wrecking yard and bought a torsion bar from an s-10 blazer to make a sway bar for my race truck. I never ended up using it, because my shock spring setup limits body roll well enough that I dont need a swaybar!

Very true. . .I should have been mores specific and stated that I was describing the purpose of a sway bar and not a torsion bar.

PORNO, dude, just make the b!tch a center seater and youll never need a torsion bar now if you have 2 seats in the front, it might be a LITTLE bit if weight bias...... and well thats another story :D
