Outer Limits 4x4 Board

this is your basic A-frame setup, like POS and afew others have.

Yes you are right.

I love when tech questions are answerd so easy


Next Question

now my question is, will this design be as effect and will it work?

In a hilux it is hard to run a good coil setup with out removing the fuel tank, which i really dont want to do. I have looked at calbahs and dont believe theres works all that well and think that this maybe a better fix.

NICK

how about a panhard rod instead of the "A" frame

yeah that has crossed my mind and seems like the easy option but from what i have seen coil suspension seems to work better without a panhard.

NICK

looks to me like it might not be real strong, but i could be wrong

i think it will work fine if you build it well.

the a-frame is supposed to stop wrap and to prevent lateral diff movement. whether symmetrical or assymetrical, it should still do so.

bill forrest on the pirate did this and it worked.

The second design will not sufficiently prevent lateral movement of the axle.

Have you thought of triangulating the lower links at the chassis and running your upper links parallel ?

I think this might be better for you nick, cross the lower two over and mount say off your bash plate, even incorporate a skid for your rear diff or tailshaft.

run paralell uppers. or waht about converging the upper a-frame to the chassis and not over the diff?

that one pissy link wont stop side to side all that well.....

Hve you thought of a Watts linkage instead of a panhard?

I know you said you didn't want to remove the fuel tank but it seem by doing that you can set the suspension up in a tried and true method. Moving or replacing your fuel tank with say a fuel cell might be the simpler mod than trying to work around it

That setup is very similar to the A frame 3 link rear that Spidertrax in the US do for the Zuks .. If the upper link is well made it should hold together.. but a properly triangulated upper would be preferable..

Also if you are goin that deep into the mods, you may as well move that tank and centre it under the vehicle blah blah blah ...

Have a look at these and see what you think.

And if it is a early Hilux a GQ tank fits behind the rear X member.

i have seen a conventional a frame used in a coiled 4runner, where the tank remained in the normal position and the A frame mounted to the standard mounts on the crossmember for the og upper arms.

the a frame reached over the axle and was tied in from behind. looked wierd but worked real well.

have you seen the panhard rod set up on a falcon it keeps the diff centred even when raised or lowered. as it works by having two rods runing from the sides to a piviot in the middle of the diff. they work really effectly

That is the Watts linkage Area54 was talking about.

this is the watts linkage

Nick cant realy move the tank because he has bobbed his body and there is not enough room behind the diff. This is in a 4runner.


Antt that is an Airbag Set up is it?
Whats it in?

what ruff said, that is my main reason for not moving the tank, i have a tank that will fit in the back but it is only 40L and i fell that it puts to much weight behind the diff.

I agree with the 1st comment.

The disadvantage of triangulated lower links and parallel upper links is a lower roll centre. That could be worse than disadvantage of panhard bar.

yep ruff, its a bag setup, its in the back of this lux

Interesting looking set up. How come you've used the watts link as well as 4 control arms? It looks like this would limit articulation , but I suppose it keeps the diff centred under the vehicle.

it's not meant for articulation, it's in the back of that lux that i posted a pic of. the only reason the lower control arms are there are to mount the airbags to, to create a cantaliever setup to get bigger lift out of the rear bags. i'll try and find a pic with the back fully inflated

with the triangulated uppers what is the sense in having the panhard rod? just out of curisoity?

I was just thinking the same thing...

all for show, just like the lowered lux

thats what i think planb, i've never seen another airbagged truck anywhere with a watts link.....just something different i spose
