Hi to all Has anyone with a GU Patrol Coil Cab fitted air bags other than polyair to their veh. The bags (not sure of brand ) are to be fitted alongside of coil, not inside them , to where the rubber bumpstop is fitted and to the plate on the dif . thanks for any info.

Sounds like polyair bags twin sisters - polyair bellows.
If this is the case I can vouch 1,000,000% for their efficiency, effectiveness and resillience to 'homocidal' treatment by myself in a 3 & 1/2 tonne Troopy.
I actually managed to compess the bellows that much that they caused the top mounting plate to wrap itself up around the chassis rail and didn't burst or leak.
Still operating actually, but will have to be cut out with an angle grinder when I come to remove/replace them.
Back to your situation - Mate! you need to be real sure that you can mount the bellows alongside
the springs without them interfering with each outher.
No idea how easy/hard it would be to install in that situation.

'Lucy', I have those firestone bellows on my navara. cost $800 and fitted them myself (I have leaf springs not coils though). I think they're great and have had them on for maybe 2 or 3 yrs now. The handbrake cable half wore through one of the bellows a year ago and I re-routed it. No probs with that so far. They hold their air pressure
well; I range from 10 psi to 50 psi depending on what ride I want or, as it is primarily a
farm ute, depending on what load I might be carrying. Rus.

hi Bugger Me
yes there was actually a leak. It was at the top of the airbag, I had to take out coil, you will recall that I had them repaired at alice last year. the mechanic at Top Gear in alice wrapped insulation tape around the new airline when he fitted it and then pushed the spring over it ,but the hose couldnt move inside the spring with the tape on it and eventually pulled off the fitting just enough for a slow leak . the other half does know that it is fixed but dosent know Im still looking for an alternative .I looked at some that fit to the F series and I think with a bit of modification to the holding plates they may fit , they are thinner but taller than arties and should fit between the coil and wheel comfortably. I will do some more homework and let u know

there is also an air bag the same as the trucks use that replaces the coil spring i am also interested in these but have not been able to talk to anyone who has them fitted, they seem to be the best compromise as u can have the vehicle sitting at a standard height for normal use and when towing u can just level it up or when u go away on a trip that more ramp over clearance is needed u pump up the front and the rear.

Hello Carree,
I think the best option for the extra weight would be uprated and longer springs as this solves the problem of the bumpstops and bump plates getting mashed off the axle and chassis. You have obviously realised that polyairs on a rig like yours will either break the spring seats or give the rear tyres a high mortality rate so you may have to put up with a stiffer ride when travelling empty around town, Athough.....
check out some alternatives like the airbagman...they replace
the springs with airbags and yes they do have adjustment. A friend of
mine has used airbag
suspension in his custom camper trailers and couldn't be happier...once he got the damper rate of the shock absorbers worked out.
check em out... Site Link
