Have fitted the Airlift poly bags to my 99 TD Jackaroo’s rear springs (need to keep the Jack level when the Campomatic is hitched - hope it works !). A few notes may be of interest. Bought from www.truckspring.com in the US (thanks to those forumites for the research). Learned later that the Airlift people invented the bags (or claim to – 50 odd years back). Must be the very same product sold here as Polyair (stamped as such on the base). Great kit – everything there – copious instructions, couple of stickers AND a Truckspring pen ! Only snag was it arrived in approx. 20 days – not 4 / 10 as indicated. The price landed here ALL UP is half the asking of $320 in SA metro ! (sorry – can’t support exploitative Aussies – hell – the Truckspring mob and the manufacturer are making a profit on that 50% - these things are about as sophisticated as a plastic coke bottle). After having fitted them my thoughts are:
1. Jack the body up – sit the chassis on some stands - watch the brake line extension – no need to release the shocks or take the springs out !
2. Fit the lines and clamps to the bag outlets – thread the lot through the lower part of the spring
and out through the hole at the top. and don’t forget the black protector disc for the top in that equation (I found it a real bugger to get the line properly on plus clamp, IF you fit the bag only first).
3. Warm the bags up in a bucket of really hot water fold them up length wise and feed them through the spring. Blow a bit of air into the lines to pop them out to size.
4. Finish off with the line routing to a convenient spot for the fillers (mine ended up on the flat shelf just under the right rear barn door. I used some split cable protector for the lines too.
Whatever – that’s mine.

Airlift Kit 60783 is the one I bought - there is a Firestone kit too. I emailed them with what I wanted, and provided the full delivery address but NO credit card details - I then phoned them during their business hours and supplied the Visa detail. I happened to deal with Mark Warezak - a helpful and organised bloke. You can open an account with them on line (even though it has no international interface) - they suggested that as an option - allows you to supply the credit detail in a secure manner. I chose the phone. This link might work to my Airlift 60783 kit.As mentioned, the delivery took about 20 or so days. $70 US plus $40 US postage - no duty or GST here (price is below stat. limits) - arrives at your address for that.

Banjo,

A very comprehensive and informative Post mate.
Just might have to tickle up the suspension on my Jack. Same vehicle, but petrol.

Well done!!!

Banjo.. nice details on the purchase & installation
May be a silly question... but once installed. how do you 'pump up' the airbags? Does each bag have a line with a simple 'connection' on the end to allow for pumping up via a 'standard' compressor?

I have a Holden Frontera 99 model.. have just given ita a partial lft via a new set of King Springs... and was looking for even more less 'sag' when towing the trailer! definately looking into the www.trucksprings kit!~

G'day Moz - the bags have a small brass oulet built into them at the moulding stage (centre top). This sits inside a black rubber spacing disk that is supplied - the supplied airline material is clamped onto the brass outlet, and then plumbed out through the top spring mounting through to the fillers. These are standard tyre inflation pattern - you decide where you want to mount them. My bones are a bit creaky, so I put them on a horizontal shelf (single skin - drilled 2 holes) so that I don't have to bend and peer into the gloom, in order to adjust them. See a pic here.....the right rear barn door swings in over that shelf and clears the fillers nicely - lines are plumbed high to avoid stones - I used some sheathing to add protection, mainly against wear.

Thought you guys might be interested in an alternative to levelling using airbags.

I have a one tonne offroad 2 axle camper trailer that has fitted airbags to the front axle.
(so none on the vehicle - Series 80)

Some pluses:
- aids balancing the rig, by distributing camper weight
- there is enough air to raise the rear axle completely off the ground when hitched
(good for tight turns, reversing into a bay, changing a rear tyre)
- current centre of gravity is right over the front axle, so I can spin it with my
finger on the front wheels, when the rear axle is lifted, even unhitched
- take the air out of the front axle bags and it sits squarely on all 4 wheels
- best of all, the compressor feeds airswitches at the drivers console, so I don't even have to get out of the drivers seat ! Couplers near the tow bar are ordinary tyre fittings, so don't always need the car to supply air, just an airline.

Might do the rear axle yet too, then I'll be able to walk the trailer out of deep sand
or replace a front tyre without a jack.
Well, that one's just a theory at the moment.

Banjo,
Camper was custom built by Australian RV Trailers (sponsor of Camper page) www.austrvtrailers.com, but the air bag system was my idea and I had to keep pushing to get what I wanted. The combination of heavy duty leaf spings and airbags needed tuning.
I also built my own website with more pics of the camper at
http://www.wychweb.com.au/rvtrailers/ .
The console air switches and connections were fitted by Northside 4x4 www.northside4x4.com.au just recently.
If I had to improve on what I've got, I would fit an air reservoir so I didn't have to wait about 60 secs to inject the air via the compressor.
i.e. there would always be enough air on hand for this and the rear diff lock I have. I hear people use old fire extinguishers for that, but I'm running out of room to put things, not to mention yet more weight !
