Post subject:  Jimny swaybar twist force disconnect.
just woundering how much twist force a swaybar has as a maximum. im thinking of making a quick release swaybar for my jimny. after seeing cz ice jimny with one i got a idea to do mine simular. few questions.

- is a swaybar made of cast iron or mild steel?
- what size diametre high tensile pin would be suited?
- would 4mm tube sleeve be strong enough?

here is a pic of what i am thinking. also on the right hand side i will weld the end of the tube to the swaybar and also some plug welds. drawing isnt to scale sorry.

cheers andrew

a certain someone destroyed my sway bar when removing it :(


BS!!! You can have the good link of my sway bar then ya big girl :roll:

Also where the pin goes through the hole on the out side sleeve, i would be putting a washer on both side's of the hole so it doesn't stretch over time with all the side way's movement's.... if you get what i mean :)

the inside 1/3 of solid bar resists almost no torque for what its worth.
i would be using at least 2 pins and the wall thickness of the sleeve of at least 1/3 the diameter of the sway bar.

I could do the calculations for you at to proper sizes but really cbf on a friday afternoon when ive already had a few beers

are they solid bars on a jimny?

youll never ever get that pin back in without the help of a jack to get the suspension level, the force there will also be huge

what are the end links like? you are better off coming up with something there

That would be a nice option but without being very creative there is no easy way to just disconnect at the links. The ends of the bar would just slap about and make contact with everything. There's no way of hanging the stock swaybar.

I've seen a couple of aftermarket versions that are similar so chances are it should work fine. I could be wrong but I'd think cutting the bar in the middle would mean splitting the torsional twist across two short links instead of one long length would make for a stiffer result when it's locked.

You talk so prrrrty, I would of just said, " you'll f*#k it if you cut it" :P

that pin would want to be strong, can't see it lasting long...

APIO's design love to hear from some one who has used one but this what i would have tried too

so when the pin is OUT in offroad mode, what holds the sway bar from falling out or moving out of bushes??

mate i can't see any further through the steel in the pic than you, but as a product sold by APIO (which is light years ahead of any Aussie or Pommy Jimny Products company) that problem would have been covered.

I imagine it would look something like this in the coupler

I could be very very wrong though

thanks for everybody's feedback. im going to pick up a spare swaybar and modify that, just incase shit goes wrong. i imagine doing something like apio's/weaves design.

Thats a great idea like that, but as royce said getting the pin back in would be a bitch.

So maybe try this instead. Get a bolt and nut set up so you could undo the bolt right out. BUT have the end of the bolt looking like this so that as long as the hole is close as you screw it in it will self centralize and lock back in place super tight.

Noob cad ( with upgrades cause I found the line thingy)

The second one would have to have NO thread going through the hole and it would need to be machinined to exactly the same size as the hole in the sway bar too. Maybe even put a thin brass bush in the sway bar so you have dissimaliar metals so they cant corrode together

All the welding would be to weaves designed bit too our other wise it will just snap out really quickly. The bar would probably have to be post weld heat treated too, but in the design stage I would just slap and see what happens.

I think the price of seirra sway bar just went up ten fold.......

Don't use a bolt use a spring loaded pin that pulled back by a cable in the cab like a handbrake or something
That way when u can shift on the fly
Quick sway from side to side would line it up to go back in if the spring force is enough

lol.....Good luck working with spring steel :wink:

what about something like what the factory swaybar disconnect on the rear of the GQ wagons, it only releases one side by disconnecting the top of the RHS sway bar link.

not really up to speed on where & how the jimny front swaybar hangs & locates but could it work by dropping only one link?

they're pretty long, but i think with a lifted jimnys you probably should extend the links to get the sway bar working in more of a horizontal plane.

did any more thought go into this? was thinking of EXACTLY the same sort of project this morning and stumbled on this thread.

Nothing from me yet. I guess I'm still happy enough to keep going with my system. Means getting under the car for a couple of minutes before and after wheeling although it does suck when it's all muddy.

howr you doin it nutter?

Post subject:  Re: swaybar twist force
I just undo the four bolts that hold it to the chassis and let it hang by a centre support. I used to have a rubber ring but now I just use a velcro strap.
Clunks around a bit but has never been an issue and saves having to totally remove it.

This link will take you to a page on my old build thread which 3/4 way down you'll find a pic.
