air bags that fit inside a coil spring

The van has a treg hitch fitted to it was on it when I bought it.Towed it back from Melbourne with no problems but it wasn't loaded up then.

It aslo has a set of level rider bars fitted

hi was taliking to the man from arb store abut air bags and said ti stay clear of the air bagin coil ones as they punture very ealsy iwent and put on poly air bags wich r very tough nio probs cheers mick

the red poly airs do fit inside the coil spring. that is how they go and if u get a kit to suit a leaf sprung rer end they come with coils to contain them.

Iv.e got poly airs under my GQ wgn .have had for many years with no problems
I don,t tow a van but when we go outback with the dirtbikes its very heavily loaded . the only thing thats noticeable is it oversteers when loaded an the bags are pumped up .
they work very well

Its not the back you worry about its how much taken off the front and airbags no matter how hard you pump them dont and cant replace the weight on the front wheels.

Only a properly setup WDH can do that.

This has been thrashed out endlessly on various forums in the past and has also been tested in 4wd mags and proved to be correct

The level riders if they are the shepherds crook bars are not suitable for a van of 2500kg.

Hi Ray,
Did they supply the dash gauge as well?
What size hole did you drill through the guts where the 12mm bolt is for the bump stops that the air hose goes up through?

Hi Hairs & Fysh,
It was some time ago but I cannot remember drilling a hole through the bumber stop mounting but can remeber cutting the bumper stop off. Trucksprings .com supplied everything that I needed including the pressure gauge. Delivery from the US was exceeptionally fast.

Thanks Ray,
I was thinking a gauge near the dash would be a good idea.
I tow our Jayco Swan, which is pretty heavy at 1200kg empty, also a horse float with a pair of Nags in it, as well as my Carpenters work trailer. So tow ball weight can vary as well as the gear that get thrown in the back, like horse gear, bags of cement/concret mix and other building produces.
Cheers.

I would suggest that you do a few measurements before and after hooking up.
If you have 300kg on the ball your front guards will have risen about 50mm at least.

Pumping up your polyairs wont alter that as they only lift what is above them.

The best description of WDH effect I have read is
Think of a wheelbarrow Push down on the handles till the wheel comes off the ground Imagine the legs as your rear suspension.

Put the legs on a large block of wood or something.

Apply the same amount of weight to the handles.

Does the barrow level No because it cant. It only lifts the point holding the load higher.

However straighten out the joint between the van and the car and it then pushes the front down a bit pivoting on the rear suspension.

Thats what a WDH does and Polyairs cant.

There is a slight resistance from front springs and engine weight but the same applies.

A guy where I used to live towed a big Coromal with a Patrol and no WDH I would hate to meet him on a wet road as from a 100 metres away you could see right under the car the front was so high.

He didnt need a WDH "it handled fine" Used to put skinny split rim wheels on it as well.. No wonder there is accidents.

"This is all I use to tow my 2.5T van"

Sorry I should add that the polyairs are not all I use, I have had the heavy rate coils put in in place of the OME coils in my Green GU.

Graham, I understand the reasoning for WDH and do believe many setups require them. The more you tow, the more you can gauge when they are required. I have on occassions required all my brakeing power to avoid animal strikes and trust me when I say the way my setup (the Green GU and Van) handles in this situation gives off nothing but confidence for the driver (me). I had a similar emergency brake situation to avoid a large roo on route to last years national EO gathering in St George but this time I was towing with my "other" GU (the grey one) and this combination was very different to my usual green Gu and van. If I were constantly towing with the grey GU I would require changing things to inspire more confidence.

Thanks for your comments, and on the whole I agree with what you say.

Cheers, Trevor.

I also have EFS Progressive springs in my Cruiser and STILL use a WDH.

Braking of course will put the weight back onto the front wheels and its the way you set the brakes up that gives you the confidence.

Rather different if you get caught on a wet slippery road with not enough weight on your steering wheels.
Different story then.

However you may do as you choose but I prefer to go with the believers rather than the deniers and know my rig is balanced correctly and just doesnt "look" correct...


Cheers

Valid comments Graham and duely noted by me.

Regards, Trevor.
