Just wondering what experiences people have had with the different air bag suspensions, good and bad??????
i have the poly air version and dont think they are a huge help, have other people found this?
are the firestone airbag man type going to be much better?
if going to remote areas is it better to have good springs only so their is not the posibility of airbag failure?
or is it safer to use a combo of springs and airbags to the load is shared and still got some suspension if one fails???

I've got polyairs inside my coils and love em. I had one pop on a 45 degree day after spending 40 minutes climbing a very steep hill in low range first. It was right next to the exhaust pipe. Polyair replaced it free of charge and supplied an exhaust shield free as well. Had no problems since.

I've got the airbagman in the rear of the Paj, and they provided a heat shield from new!
Loves to rattle though on corrugations. :-(.

I find they are great too, even with the stiffer rear springs, seldom go over 15 psi even fully loaded.

Hi Dingo,
I ran Polyairs in my Mav for 10 years without a single problem.
Have had them in my GU for the last 5 years without a problem.
In the Mav, I used them in conjunction with a 2" lift in the springs, in the GU, I have standard height.
Not sure what the reasons are for your disappointment, but I find them great for restoring ride height when laden. What I like about them over stiffer springs is the ability to let them down when the vehicle is unladen, giving a good ride.
My only criticism with the first install was the idiots mounted the schraeder valves right out on the rear bumpers, ready to get knocked off when reversing. I shifted them to a less susceptible location.
The only proviso I might add is to ensure that the inflation tube is installed so that it cannot be damaged by whatever means, as I've heard that daggy installs have resulted in the tube being pulled out.

hi Joc
they prob arny as bad i recon, just cant get rear up to the height of front which only has springs!
this vehical is always fully loaded so perhaps there is less advantage for air bags in this case???

what sort of weight do you carry in the GU, and do you tow a trailer. I'm thinking about polyairs in the back of our Terracan to counter the weight of the camper(especially for Fraser Island)and probably go to a heavier spring as well.

Cheers Greg S

Hi Greg,
I don't tow, but I do load it to the hilt; ie, shelving in the back, absolutely full and roofrack well loaded with tyres, spares, etc. My first Kimberley trip in 1990, without polyairs had the axle almost on the bump stops.
The max pressure on the polyairs is 30psi, and I run about 20-25 to get the ride height back to normal, so there is still some leeway if you really run heavy loads.
Cheers, Gerry

I run poly airs in the rear springs and I think they are great. I have not had any problems with it.

I was at the Supershow today, and I got quoted $260 for the bags and $120 for fitting.

Do you guys think it's a fair price?

I can't fit them myself at the moment due to an injury, so have to get them installed.
