I would be grateful if i could get some advice on whether to install Polyair bags to my Nissan 02 pathfinder.
The paramenters are
- I simply require the ass of the car to be lifted as i drag a camper trailer and it pulls the soft ass down.
- I am quite happy with the standard of
suspension in its current form for the amount of off road work that i do.
- the cost of 4 shocks and 2 springs is around $800-00 and i still may get the rear end dropping down (if the spring is not "stiff" enough) and to boot a ride that would undoubtedly be harder than the current
suspension.(which i am happy with )
I am lead to believe the Poly airbags are prone to busting (stick impact and chaffing) is this true or not i would think that the chance of getting a stick impact is pretty low.
Seems such a waste to repalce good
suspension that i am happy with and thees Plyairbags will (I assume) provide as good a result for my "limited application"
They sound like a godsend at $424-00 fully fitted
Any help would be greately apreciatted

Quite a few threads on this
forum on this subject.
I ran Polyairs for 10 yrs in a GQ, not a single problem.
Now have had them in the GU for 3 years, again no problems.
On the QG, the idiots fitted the schrader valves right out on the ends of the back bumbers, ready to get bashed off; I shifted them. When I had them fitted to the GU, I prepared the fitting spot for them. Re getting the air hose ripped out, just make sure that the hose is tied up
well out of the way.

Kim,
We've done a lot of homework on getting Polairs for our GU and will definitely go ahead with them before our next trip away. Same reason as you as we just need a bit of extra support when towing our campertrailer. The OME
suspension is in good order and as most of our driving is around town, we don't want to have a permanent
suspension lift. I know several people with Polairs and all are happy. None of them have had any problems. I wonder if those that have had bags fail through bursting are due to suspect fitting. Although of course, freak incidents do occur from time to time when you're 4Wdriving.

To all that respnded,
It would appear that the Polyairs are a graet idea.
I noted the comment re stiffre springs but thsi si the same idea as a stiffer spring and will ensure that theb ride height can be adjusted "to suit''... NOT the case with a new spring... you get waht you "get" .
It would appear that a stiffer spring requires a new shock (or so i am told by the 4wd store..... seems to make sense to ensure the valving matches the new springy thing (new my bike days would one day come in handy) .
So given that they can actually extend the life of the spring and shock AND there is no "guessing" that would be the case with a new stiffer spring fitted ,...go the Polyairs.
Imagine a new spring fitted (and possibly shock) and finding out it is NOT stiff enough to handle the load.... then again throw in some Viagra Polyairs and wellllllllllllllllllllll here we come ):):):):.
Cheers to all

I was thinking the same as you when I looked at this 6 months ago. I fitted Polyairs for our
Cape York Trip in August. I couldn't be happier.
Compared with new springs you get the best of both worlds and a broad range of ride settings according to how much load and what pressure you decide to run.
I carry a small bike pump so that changing the pressure is dead easy.
Just remember they say to inflate before you load up. After loading reduce pressure to obtain the desired ride height. Don't inflate after loading.
Regarding the risks, I concluded that there are plenty of serious 4WDers who have had a good long run (8-10 yrs) with them. So its hard to go past them.
I can't believe anyone would contemplate having two sets of springs / shocks - one set for off-road and and another for on-road.
