I only found one Thread on this, from 2010.
My Elite van (single axle) has it fitted with no shocks.
Seems to track on the bitumen OK but I want to go to Birdsville and up the the Strezlecki through Maree.
The height looks good but I am not sure whether the suspension will stand up to the corrugations etc. I don't speed on corrugations (30 to 40 kms or less) so I will treat it nicely!
Thanks

I have found a picture/article explaining the rubber components if there are readers who are not familiar the system.

It'll be fine....that suspension is pretty indestructible. Whether the contents of the van are up to it is the 60,000 dollar question !!

The Al-Ko version of this type of suspension is far from indestructible!

I agree this design of suspension is far from indestructible.

Suited only to smooth roads in my opinion.

Similar designs have broken the axle off at the side of the arm and or become twisted slightly and negative camber develops. No adjustment for that. Also, the axle doesn't project through to anything for a length of support, unfortunately.

There is only a certain amount of travel and isn't as compliant as a good long leaf spring or Independent suspension coil/shock.
The rubber hammers and the arm oscillates wildly on corrugations as ther is not much dampening despite claims.

If going on those roads, going slow and deflating the tyres, so they become a vital part of the suspension action would be required so the rubber units aren't stressed to the max.

Used to have an 18 foot dive boat whose trailer had Duratorque with no shocks.
Worked great and gave no problems.
They do suffer from the rubber perishing so maybe get those replaced. Have to find a specialist as they are fitted frozen with liquid nitrogen.

Hi
Not all rubber torsion suspension can be rebuilt non- repairable . The imported rubber suspensions even if rebuildable in some cases cannot be done due to no factory support in OZ.
Tyre wear and tear is the first u will notice which will indicate an issue .
Not an issue in reality by itself but combine that with axle movement in and out and the suspension then needs a rebuild .
There is no way of predicting failure with these units .
The cost of over haul is expensive .
Operate with caution on rough roads .
