Has anyone seen or know about the use of rubber torsion bar suspension common on boat and camper trailers here in Australia used on sidecars
I have a link to a page http://www.alko.com.au/vehicle/axles/irs.html
They come in various load rateings and from what ive read in different uses they are very tough and long lasting
Thinking of useing one
Thanks Tim
I built one that way about 6 years ago.
I used a half of a light trailer axle and welded it to the frasme I had fabricated.
It worked well but remember that unless you add a shock absorber of some kind, it will rebound a little.
I notice that now you can buy a stub axle of the same type from Harbor freight.
The lightest duty one is for 250 lbs rating. It uses the torsion for a 500 lb axle but since your will only be using one end, the 250 lb rating.
I have seen a very heavy one proffessionally made by Dauntless motors,
(a sidecar builder in Enumclaw Washington State.
It carrys a huge refridgerator box for selling ice cream. I think he used half of a 1000 lb axle.
Note that when welding it to your frame, DO NOT weld on the hollow square that contains the rubber torsion pads. Weld only on the plate that comes already attatched to the axle. Or bolt it to your frame. Ther heat of welding will destroy the pads.

Keep a close eye on tire wear. After miles rack up some play can develope that can affect toe in.
