Coil spring air suspension

Great. That’s the same as I’ve ordered
How are they when empty and alternately when full loaded. What pressures are you using.

With 260kg tow ball weight running 45psi. Rides with a lot more confidence, and level with van. When empty I leave about 20psi to keep shape. have Engle fridge, double draws and kelpie in the back

I'm at 230/40/15psi

Where does it say that? The link is for the high pressure bags.

Hi Tazzieman
Where did you get the air valves fitted. I am fitting the airbags myself. Thanks in advance

Just below the rear bumper

 

[Steveo]

I have air bags available for both standard height and eibach pro lift springs shipping to USA is $80 AUD

@GrenX to get the valves to that location what level of disassembly is needed? The whole rear bumper off?

Thanks,
Steve

I'm not GrenX but I installed mine. Simple answer is no, you can reach that location either by pushing the bumper material (plastic) down or from behind in the wheel well. No disassembly required.

This is correct you don't need to remove the bar to fit the valves, its easy and protected location from mud and dust. We have fitted some for clients where the petrol filler is but its more complicated install so I prefer the bar location.

I know it's been a minute since this thread was updated. Anyonw in the US care you give a review of the bags?
I found that I'm now roughly at 800lbs additional weight on my car. Underbody armor. Roof rack, awning, drawers, tools and steel skid plates.

I'm wondering if I would benefit from air bags. Looking for feedback and reviews.

 

[parb]

Also...
@GrenX do you have install instructions for your airbags?
Trying to decide how much of effort it is.
What is the main difference between your kit and the airbag man kit?

I'm the guy from California that stopped by your place in Melbourne last November.

If that extra weight is going to be constant which in my view it will be, then Eibach spring upgrade would be my choice. Air bags IMO come into their own with trailer and caravan towing that is not constant.

I got this article yesterday via the newsletter of a fairly respected Australian 4WD adventurer and educator - Pat Callinan. It's on point for a sidebar discussion about airbags.

5 Things most people get wrong about airbag suspension

Advice

unsealed4x4.com.au

The info is supplied by an Aussie company called Airbagman which @parb noted above. They do a few different Grenadier kits with or without high pressure sleeves for high pressure applications (higher loads) and for standard height or raised suspension. Details here.

GrenX supply Polyair kits. Different brand of components.

Market choice is healthy

I am seriously considering getting airbags installed.
I packed up my truck for a longer trip and I could feel how the springs compressed and it swayed more.

Question, I have onboard air. I assume I just use my tire inflator?
Also where do you guys place the air nipples?

In the US they sell these

While convenient I dont see a great place to put this kit.

1. Most airbag kits just use the standard tire valve and you use a standard tire inflator. Your onboard should be fine.
2. Most air nipples are placed around around the rear bumper, either in or under the bumper.*
3. You do not need an integrated air compressor, any air hose can inflate them. Airbag kits with integrated air are always way more expensive.
4. Match your air bags with any lift you have.

I am seriously considering getting airbags installed.

Deflate to 5-10psi when going serious offroad i.e. unhitching a trailer then hitting a rutted track where articulation is tested.
Here are the cautions (possibly included with your kit; this is something I got from an old post on a LR site):

''Caution - Do not inflate air springs while vehicle is on a hoist. Vehicle must be standing on its wheels before bags are inflated.

• Maintain at least 35 KPA / 5 PSI of air pressure in the Air Lift Bags to prevent chafing.
• Inflate your Air Bags before loading your vehicle to maximum pressure indicated on fitting instructions.
• Do not attempt to raise a loaded vehicle by inflating Air Bags. If loaded, jack up body until level, then inflate.
• It is recommended that tyre pressure be increased by 14 KPA (2 lbs) above normal for each 45 kg / 100 lbs total overload on the axle.''

Thanks. I added a link to these tips over at the Resource Links.

This is where inflaters are, I have the Polyair bags.

I think I'd also like to add heavier duty rear springs. Does anyone make those yet? (I have the Eibach springs that provide a small lift, but I don't think they increase the load capacity)?

In Australia, there are 3 load ratings for Eibach springs.
