i want more travel so has any one used the 3x3 arms on a bus irs torsion? what about a torsion elimination kit on it so coil overs can be used?

In the process of doing that on a build right now.

Beam Build

Get rid of the torsions!

When you change to longer / wider arms, you need to also convert to coil over shocks. Otherwise you do not get the benefit of the longer / wider arms since the point of this conversion is generally for more travel.

right, i want to get rid of the torsion, but i think i have a bus torsion beam. i don't see any thing listed for it. who else has this set up?

Just get a set like this and you can eliminate the torsions.

Havasu you have a type 1 torsion he has a type 2, they are different those will not work unless they are made for the bus, nor will 3x3s just bolt up the inner pivot is different.

i have a bus torsion housing in my hi-jumper frame.. its kind of a pain in the rear haha.. what i have found out is you need to add new pivots and build custom spring plates cause the 3x3 arms are for a bug housing which the mounting is different (narrower) my housing has the original bus mount and the new mount for the 3x3's. i want to go to coil overs one of these days but the check book says no. i also read something on here that the torsion elemination kit is for a bug housing which i think the end is different than the bus so you would have to custom make that also.. hopefully this helps a little.

Blind chicken racing makes a set of longer and wider bus arms but, they are slow to arive. Maybe they are better now.

Still probably quicker than modifying a bug IRS jig and using standard 3x3s. Their price is about right as well...

I put a bus torosion in my Hi jumper frame when everone was starting to use the Bus IRS around 1989. I tried to beef up the arms with steel tubes to keep the from bending. This worked for a while till i got them strong enough and took a flying leap and turned it into a 3-wheeler!! The cast outer hub is very weak at at the mounting location. At that time no one was making longer arms so i made some out of 4130 and dubed them "DRUNK PROOF". You can take your old ones and make a jig to fab the longer ones mine were just 2" longer that way i didn't have to change the axle length. Use the bus stub axles, the roller bearings ( bus rear) and to get rid of the tapered roller bearing machine a spacer to act like a cursh sleeve. You can also use the bus front disc brakes just machine the rear hub down to fit inside the rotor. Here are some picutres of the the arms. You also want to add a gusset accross the top of the torsion or it will bend in the middle. I slamed mine quite a few times and never had any problem with them. The set up is not light but can be done if you don't have any sources. Be careful there are two different lengths of torosion housings. The arms will not interchange.
Good luck

NICE JOB! mntbuggy
Very Nice Job!

Thanks i spent many hours in the garage building them. Kinda ( ha ha ) overkill but i never had a problem with them.

I would to agree with the Drunk Proof label, those are quite stout looking.

thanks, it gives me a good idea of what need to happen. i picked the rail up some time back, never got a chance to do much to it. now things are coming together with a motor and trans combo that i think i'll like. so time to reinforce all parts of this frame that i can.

I sure am glad I read this! I didn't even know there was a bus and bug rear end!I was just about to buy the whole 3x3 and torsion eliminater for mine but I have the crappy bus set-up. I do not like the bus set up at all since yesterday I found: where they welded the frame to the cast is all broken and needs rewelded and reinforced. It is looking easier to just cut the whole bus section out and weld in the bug style so I can do the conversion?
Has anyone done this?

Dave, does it ever end. I see you brought your world famous AV over with you.
Dont tell John I stole his, it has been a hit over here.

I can not even begin to tell you how SICK of this VW crap I am getting!! Every time I turn around I am hitting another wall with this rail. "Oh, you can't do this cause it has that" is the most common statement I've heard with this POS!! I figured getting rid of the VW motor would end most of my nightmare, NOPE!!

I am SO frickin ready for a long travel, ready to go! I keep trying to make this beam rail something more and I could have bought a long travel by now!

Besides, you stole your AV from Jerry not John

ok, so Mark over at Blind chicken racing has a set made for the bus torsion for $475.00 that are 2" longer but only stock wide. they have bug bearing carriers for use with aftermarket parts, and made here in the USA a defiant big plus for me. any on here using his stuff? i will still need a set of 930 axles and stubs, i want to stay with the rear drum brakes. whats the best places to get these from? i seen 930 axle-cv kits from appletree for $460.00 and poorboy stubs for $60 each.

I don't know that it is worth wild to buy those if they are not wider. To get more travel you need to go wider.

Also, it will put more of an angle on your CV's. Sorry, but I don't think I'd go that route.

Maybe if you show some pics and info on your car and what you want out of it. We can help you figure out where to spend your money to get closer to the results you want. Where do you live maybe somone can go take alook.

GOOD LUCK

I say Give John a call over @ mosebillt. He made me a set of custom mildsteel 3x5 arms for about 500-600 bucks. Originally my delema was that I was going to have to have my whole torsion housing changed out just so I could run "off the shelf" parts i.e arms, torsion bars, spring plates etc. etc.

It turned out being way easier to just have custom arms made. and with the money I saved I bought a set of coil-over shocks. So in the end I guess I spent the same amount of money, but i sure am a whole lot happier with 20" of travel and the fact that they are made USA and not some tawian crap that I was orig. going to get

Hope this helps

Do you have a number for mosebuilt?

yuppers 909-624-8888 John

You can see the arms he made me are on my build thread project McCheapskate!

well as for now i'm between a rock and brick wall, the bus axles are about 18.5" each but my new 091 trans has the 930 flanges and can't find 930 stubs for the bus carriers. my old 3 rib used stock 002 bus cv axles but they won't bolt to the new transmission's flanges. i am relocating and rebuilding the rear frame to hold the j30 honda and the 091 trans. i have broke one bus bearing carrier once and finding another was not fun. it would be nice to run bug carriers and have a more beefy look than whats back there now. my rail gets trail ridden over flat land, rutted trails, sugar sand for most of its off road use and see's the street the rest. i thought that a bus torsion is all ready a little wider than a bug . i am going cheep for now and keeping the torsion in use till i pay down the rest of this build.
so how do you change the flanges out on the trans? will the flanges off the 002 fit the 091?

it's an old school 4 seat frame, not a new high jumper big air machine. it works for Florida. it was powered by a 1500cc signal port air cooled, that was till i picked it up. going for modern over haul.
