weld in IRS trailing arm pivots

I'm thinking about changing my rail buggy over to IRS transmission and I now have a swing axle. Has anyone used the weld in IRS pivots. I have read that you have to use a welding jig to get them in the right place. Where do you get the welding jig. Any ideas????? Thanks!!

Any particular reason you want to do this? Building a long travel suspension or something? A swingaxle works great in a lightweight buggy, simple and reliable......

You will most likely have to make your own jig or check out some local Buggy Shops as they most likely have one. See-> http://www.1800vw.bizhosting.com/irspivots.htm

I am doing this besause the swing axle has gone bad. I have a IRS trans I could put in instead of trying to fix the swing axle. How much do the welding jigs cost. I wish I could find out how the build a jig. Thanks!

the jig is like $90.00 there is inctructions on how how to make a jig on blindchickenracing.com but you have to have a irs trosion housing to make the jig off of

I am about to change over to IRS for my rail and will just be changing out the torsions and be done with it. Torsions here run about $75 for a used one out of a old bus. Tranny is another $250 to $300 and then axles and CV joints and the odds and ends and you are done. So for about $500 or so you can have it changed out no problem.

Any special reason you want to use a bus torsion? They are wider and heavier than a sedan. A car torsion with the correct shorter axles and the IRS bus transmission would work fine for you,
Just curious.......

Turboblue, the main reason to change over to the IRS is that you have more ability to change the ride height without changing the way the tire rides on the ground. You can get several more inches of height with the IRS where you can't with the swingarm. The terrain I ride in here is mostly rocky and steep.

What I meant was why a bus IRS torsion over a sedan IRS torsion? Not a swing axle.
We run the sedan/car IRS with the Bus IRS transmission around here with good results.
The sedan IRS torsion is not as heavy and wide as a bus IRS torsion.
Guess I didn't 'splain myself very well.

Turboblue, for me it is just easier to replace the whole torsion instead of trying to get a jig made and then welding it all in. All I have to do is cut 6 places and the whole thing falls out then reweld the IRS torsion in it place. Nothing is wrong with either one that I am aware of. Just in my case and maybe some other peoples cases it might be better to just swap it all over. Remember mine is on a Railbuggy(woodscar). You can see a picture of mine in street dress on Railbuggies.com under John's in the visitors parking area of the site.
