airbag spring replacement

Hi there,
dunno about a full spring replacement, but we have PolyAir Bags on our '96 Discovery and they are great. We drive around town with very little air in them then when we go away we tow a 2Tonne camper. I have occasionally forgot to pump the air bags up before we went and it's a fight to stop the sway. We don't use any weight distribution aids but just put 30psi in the air bags and she sits very nicely. Hope this helps.

No experience here but read that they are great except that they require very good shockers and usually more than one per bag. If the shocks break then the system fails. On the upside the trucking industry has used these for a long time. Was speaking to a coach driver in Alice and asked him if he ever had one break because he did some dirt road. He said that he has had to replace one and it is no fun but reckons they are pretty robust.

Kind regards

Mattie.

I look forward to replies from users of full air systems. They are excellent gear on trucks ride wise and are extensivly used on prime movers and most euro trucks ( Volvo, Scannia etc).

My observations to date are that :-

Good quality shocks and/or more regular replacement is required with air bags.

A seperate suspension travel limiting device must be fitted other than using the shock absorbers.

i will now go back armed with a few more questions about the shockie side of things thanku for your replies

Sorry for the late reply. I have a 2000 model troopie which had 2 ordinary rear springs (crappy Jap Steel ) Loooked at replacing these springs but came up with a cost of about $900 fitted. I looked at the Poly-Air Bellows (not the dinky red ones) at a cost of $710 and fit yourself. I went this way for the versatility, you can give yourself a 5inch lift if you want. I'm not sure that you would need a full air suspension. You can also fit them to the front suspension as well.

Cheers
