FAQs

We freight all over Australia, we can send to a Caravan park, business address, post office ahead of your arrival.
Are Polyair Ultimate Airbag Suspension kits good for towing caravans and heavy trailers?
Yes.
Polyair Ultimate Airbag Suspension kits are designed to provide adjustable rear suspension support when towing or carrying additional loads. Correctly adjusted airbags can help bring a loaded vehicle back towards its normal ride height, reduce rear-end sag and improve stability and handling. The correct setup and pressure will depend on the vehicle, load and towing application.
Do Polyair Ultimate airbags increase my vehicle's GVM or towing capacity?
No. Load-assist airbags do not automatically increase the manufacturer's GVM, GCM or towing capacity. They assist the existing suspension in managing load and maintaining ride height, but the vehicle must still remain within its applicable vehicle, axle and towing limits.
Do Polyair Ultimate airbags increase my vehicle's GVM or towing capacity?
No. Load-assist airbags do not automatically increase the manufacturer's GVM, GCM or towing capacity. They assist the existing suspension in managing load and maintaining ride height, but the vehicle must still remain within its applicable vehicle, axle and towing limits.
How do I know which Polyair Ultimate Airbag Suspension kit fits my 4WD or ute?
The correct kit depends on your vehicle's make, model, year and suspension configuration, including whether it is standard height or has raised suspension. Polyair offers airbag suspension solutions across many popular Australian 4WDs, utes and vans, so vehicle details should be confirmed before ordering.
Can I install a Polyair Ultimate Airbag Suspension kit myself?
Many Polyair Ultimate load-assist kits are designed as bolt-on installations and are supplied with installation guidance. Thor also provides installation information and video support. Installation requirements vary by vehicle, so the instructions for the specific kit should always be followed; professional installation is a sensible option where the customer isn't confident with suspension work.
Can I run my Polyair Ultimate airbags with no air pressure when I'm not towing or carrying a load?
No. Polyair Ultimate Airbag Suspension requires a minimum of 5 PSI in the airbags at all times, even when the vehicle is not towing or carrying a heavy load. On applications where the original bump stops are removed during installation, maintaining at least 5 PSI allows the airbag to provide bump-stop support while helping protect the airbag and suspension system.
How much air pressure should I run in Polyair Ultimate Airbag Suspension?
The correct pressure depends on the vehicle and the load being carried.
Polyair Ultimate recommends starting around 30 psi and adjusting the pressure for ride comfort and vehicle levelling. Thor states a maximum pressure of 60 psi for its Load Assist airbags and recommends maintaining approximately 5 psi on rough roads to help prevent the bellows from bottoming out. Always follow the instructions supplied for the specific kit fitted to your vehicle.
