Whats the norm on air bags fitted inside rear springs on a Cruiser GXL Wagon. Have just been lucky enough to get a good deal on 2004 turbo diesel Auto, it has rear air bags, don't know what breed they are as haven't been that energetic yet to crawl under and see. What is a good pressure to run in them empty when just using it for a shopping trolley. No dought different loads will require some experimentation on pressure, but any info will be much appreciated. A totally different driving experience to the Colorado. Thanks in advance .

Cheers Ross.

Hi Ross. Just my opinion but I feel the blue (Firestone) airbags have better quality air fittings,hose and protection than the other brand. 8 to 10 Lb should be plenty when unloaded. They will go up to around 35Lb with extreme loads in/on the back. Cheers,Bob.

Hi Rosss,

I have Polyair Springs (Red Series) air bags under my GXL. Recommended unloaded pressure is around 5lbs. They also recommend blowing them up before you load the vehicle and then let them down to bring the vehicle back to original ride level.

Lookup Polyair Springs on the internet and you should get some more info.

Cheers

I had Blue Air Bag Man one's on a disco 8yrs ago and they were rubbish the top split on 2 different sets didn't even get 1,000km out of either set I only pumped them up to 29psi 1 pound below recommend pressure and towed a 16.6 foot van. The patrol ute I have now has got the red Polyairs in it they are 7yrs old and still good I Have had up to 700kg in the tray and they handled it at 30psi I highly recommend Polyairs if you want them to last.

Manufacturers recommend 5psi minimum, 30 psi max. Personally I recon if you ever need to inflate them fully to level your car you probably need to either reduce the load or fit stiffer springs as the few I've seen with burst bags were all running top pressure. Other issues with them is burst lines from stone damage or rubbing through at the top if the hole in the spring tower has insufficient clearance. Super glue helps stop the line coming off the bag too.
With a lot of loaded outback driving about 7 or 8 years seems to be their lifespan otherwise a great option for variable loads.

Mate if you have to super glue the air line on then doesn't that tell you there is something wrong to start with and in some cases the super glue might do more damage to the air line or bag. Just a note if you pull the hose of for any reason you NEED to cut the used section off you reattach it to the bag or there is a good chance it will leak because you have stretched the hose.

The super glue is a trick of the trade used by a couple of installers I know to minimise the chance of the hose popping off.

I've had 3 sets installed and none of them ever used any type of glue plus it would make it hard to remove the hose without damaging the bag.

No one forcing you to glue yours on Batt's but should you ever have one pop off you may consider it ;-)
