anybody?: Sway bars with SOA for DD (1 Viewer)

[bandy rooster]

sprung over on 37's just about to get it on the road was wondering if anyone else was using sway bars for their daily driving?


my brother is sprung over on 37's on his 60 and it drives great on the road but I think that added wheel base just does the trick for him. maybe later 40 series had sway bars but i was thinking of fabbing up a set for daily driving just to make the vehicle more control-able and i'm not to worried about limiting flex because i'll just disconnect them when i'm wheeling (no biggie) any thoughts.. the overall idea of sway bars seems pretty simple just thought i'd see if anyone else was doing something similar

Sway bars are an excellent idea for cornering and stability on the road.

Most people dont' utilize them on a SOA because they are fairly stable. However it is a good idea.

Put one on the front first, then one on the rear if you think it is necessary.

I'd take it for a drive first personally. My friends don't run them and theirs do pretty good just remember not to take that corner too fast

thats what I thought, i have a lessened 40's pack in the front and double xj packs in the rear.. it flex's like the dickens but its almost soft/softer then an 80 series suspension ( we have one sitting out back) and with florida drivers being complete douche bags the added safety couldn't hurt..



is there anything to keep in mind when building these? i guess i'll just study up on the design and build one later on...

take it for a drive ? hmmmm never thought of that thanks...if you ever have any info really relevant to the question itself i'll personally send you a cookie lol...

Be nice

you can use a torsion bar and never disconnect it (like the currie antirock bar) or go with a more conventional bar. FJ60 bar would probably work as well.

correction man....you have yj's in the rear

and to add to the subject...ive heard that adding a panhard to the front helps with cornering and driving normal speeds...i have no experience with using one, so i cant really say whether thats completely true or not.

 

[bustanutley]

I think anti-rocks would be the way to go. Are you outboarded in the front, I can't remember if you were going 60 series axles or not. Mine for all practicality is very stable on the road, but i'm fairly wide and long, outboarded in the front and I have 17" wheels.

 

[Mace]

Unless you wanted to make a removable PH bar for the trails it is a bad idea.

It would seriously bind during articulation.

 

[zucruisers]

yeah i dont like the idea of a panhard on the trail....but for the street driving i think it could help

btw wes is your 40 ever gonna make its way back up north??

 

[bandy rooster]

nope florida i'm staying...

def. not putting a panhard up front.. but i'll check out the currie thing.


edit...currie is way to expensive but i have seen that kit on an fj40 for sale on ebay before, def. looks nice but i'll have to go a different route..

 

[Mace]

currie kit is just a torsion bar.

Glorified VW rear suspension setup. A lot of trucks use torsion bars in their front suspensions go to the local pick n pull and see what is available. You might be suprised.

I think that 55's came with torsion bars for a while. Might look into that.

Going on seven years daily driving a SOA 60 with 35's. I run a front swaybar and wouldn't have it any other way, make a huge difference to run without it on the highway.

 

[fj40forlife]

I have alot of body roll I dont know if its the 31s to 35s or the ps. I did bolt at the same time so I dont know. If you do it tell me how it works out

 

[awp_cruiser]

Is a sway bar (torsion bar) as effective on the rear?

What is the advantage of running one in front instead of the rear?

 

[cody c]

the majority of the weight is in the front so you should see more roll there. my soa 60 has got sway bar in the front and im thinking of doing one in the back for stability. i can feel a big difference between front to back especially on loose gravel.

 

[awp_cruiser]

I am trying, (i really am) to wrap my brain around the Sway Bar idea. Maybe one of you guys who understand how those work will talk me through this.

I think I understand the forces and principles that the torsion bar sees when cornering on the street and how that would in turn resist the body roll.

But now I have more questions. I can see when both tires drop the bar simply rotates in the housing.

Her is wehre I am stuck. For instance, how does the Currie Anti-rock kit work "offroad" with out disconnecting it for travel? WOuldn't the nature of the torsional bar limit felx to some degree or another? I see lots of buggies running sway bars on the rear and I wonder how much torsion those bars would see at maximium stuff and droop? Am I underestimating how much rotation those bars will take? My reaction is that they only see a few degrees (+/- 10 *) of torsion before they lose elasticity.

I have always thought the bars on buggies were to provide some resistance to droop so to create a more predictable motion through travel rather than rely on shock dampening. Or is the arm of the torsion bar long enough that the travel "droop" does not exceed the torsional limits of the bar?

With some of the long travel suspensions, couldn't the torsional forces in the bar create an up force equal to the down force of the springs create some limit? Or failure in the torsion bar?

Or is it that that theoretical limit is beyond other mechanical limits that establish maximium doop and stuff?

If I can get an answer to this I'll ask the next set of questions.

Thanks for the slow talk to the slow guy.

the sway bar or torsion bar as you call it, it's purpose is to limit bory roll, or side to side roll of the body in regards to the axel. the sway bar is not meant to effect the axel in an up or down movement, which it will to some degree. depending on how much articulation you get. driving on side hills or off camber angles your vehicle will benefit from sway bars. going up hills they shouldnt effect the vehicle. the purpose of the diconnectable sway bar is too prevent the bar from limiting axel articulation. it is an advantage to have both wheels touching the ground over obstacles especially with open diffs. as far as the sway bar having limits or impedeing suspension performance you are right. the toyota sway bars are onl;y made for so much movement of the axel. obviously not designed for giant coils and rock crawling. the aftermarket will help in this area a bit. i dont know how much aftermarket disconnectable sway bars are but i think you would definately enjoy the benefits of having them on your rig, especially if daily driving and heavy trail use are how its to be driven

Here's a short answer no!

SOA 60 I LIKE THE LEAN but thats just me

your in a 40.... so i don't know

A sway bar and a torsion bar are two different things; a sway bar is only disgned to transfer downward forces to the opposite side of the body decreasing body roll. A torsion bar is designed to twist and on late model chevy's is used as the spring on the front suspension.
