We start from the premise that Big Red is bloated and so is the caravan.

Prior to a visit to Carrolls our rear air bags were 90psi and the front 40psi and we were almost flat on the second stage spring.

After spending $1500 and adding two leaf springs in the rear plus something done to the second stage, and an additional spring in the front, we were raised 80mm in the rear and 60mm in the front and the air bags are inflated to 20 simply because you shouldn'[t drive with them empty.

The price also included returning after 500k for a tensioning and tightening, and returning after we take delivery of our new heavier Boroma and having the entire system reevaluated and balanced.

The Rancho 9000 shocks were still in very good condition and nothing need to be replaced.

I should have done this a long time ago!!

Cheers, Ja7y

Jay,

My 250 is in at ARB getting their new OME suspension kit fitted and will pick it up tomorrow. I have also installed one of those huge RTC Tough Dog steering dampers so it will be interesting to see how the truck drives from before.

My only problem is that I had Polyair air bellows in the back with the standard suspension and now they do not fit because it has been raised 60mm and the bags are to short.

I can put spacers in to make up the lift but the problem is when the suspension travels it fullest when one wheel drops down the air bags would probably tear because of the extra travel.

Did you use the original air bags after fitting the suspension and if so what make are they as I know Firestone do have a longer air bag that will fit but Polyair do not.

Cheers
Stewart

Hi and I do not have the answer!!

When Carrolls does there "thing" they remove all air from the bags so that I had to put 20 psi "just because".

I am using the Firestone bags and when I did a quick look nothing seemed changed or stretched in that area.

I will ask them what they did regarding the bags in light of the 80mm rise.

Stewart, in looking at the bags they are - in a sense - squashed/not stretched!

The leafs have simply raised the bottom attachment plate of the airbags closer to the chasis.

Hi Jay,

I think the bait was "Jay" and the take was spectacular, (lol) the return cast, honest and to the point.
A simple ( I'm happy with work done story) gone mad, at least no one jumps down your throat on this site any more.
The spring job was recomended to me by Alf Horn, and in turn I have recmended it to several others,
Any way have a good one
Graham

Graham, from his self-serving ego stroking response to my simple post I guess everyone now knows why I would not build another BT. It is a great product for the sometimes severe - if you choose to go there - outback of Australia. I would rather slightly limit my options of where I can go rather than deal with him in the future.

Look forward to seeing all of you Boggers on the road "somewhere".

Cheers, Jay

Finally picked up the truck with the ARB suspension and the lift was more than 60mm up to 80mm and the air bags do not fit due to the lift.

The big RTC steering damper has made a great difference and there is no wander anymore and the short driving I have done the truck drives totally different.

The only problem is that the steering damper is quite low, in line with the bottom of the diff and after speaking with the shop this is the way they are on the F250 but I like the more direct and firmer response.

Looks like some air bags going cheap.

Cheers
Stewart

Is the steering damper come as a separate item or part of the suspension upgrade. I had the Carroll's spring job done early this year but would like to fix the wanders the effie gets occasionally.

The steering damper is separate and I purchased one of those big Tough Dog RTC dampers, bloody big with a big coil spring around it also. Cost $300, the only problem is that the damper hangs pretty low basically in line with the bottom of the diff so you would have to be careful going over rough ground with large rocks etc.

Spoke with the supplier and he said that is the way they are on the F250's but I must admit it gives a positive and firm feel to the sterring and no wanders any more.

Cheers
