N90 Hilux Polyair Bellows Kit.
The N90 Hilux Airbag Kit from Polyair Springs is now available for the latest generation Toyota HiLux, covering both 4WD and 2WD Hi-Ride variants. Whether you are towing, carrying a heavy load, or just tired of watching the rear end sag every time you hitch up a trailer, this is the fix.
Available for standard height and 2-inch raised configurations, the Polyair Bellows Kit gives you adjustable rear load support that works with your HiLux's existing suspension, not against it. No permanent modifications, no compromise on daily drivability, and no trade-offs on ride quality when you are running empty.
Why the N90 HiLux Needs an Airbag Kit
The Toyota HiLux N90 is one of Australia's best-selling utes for a reason. It's reliable, capable, and versatile enough to handle just about anything you throw at it. But like every leaf-sprung ute, it has a fundamental limitation: put a serious load on the back and the rear end drops.
Rear sag is more than just an aesthetic problem. When the rear of your HiLux sags under load it reduces suspension travel, throws headlight aim upward into oncoming traffic, reduces braking efficiency, and makes the whole rig feel unstable at speeds. If you are regularly towing a caravan, a horse float, a boat, or a work trailer or have it loaded up with tool boxes, you know exactly what we are talking about.
The Polyair Bellows airbag kit is the clean, effective solution. It adds adjustable pneumatic support for the rear suspension, letting you dial in the right amount of adjustment to compensate for the load; and drop back to 5psi pressure when you are running unladen.
Rear sag reduces suspension travel, throws out headlight aim, reduces braking efficiency, and makes the rig feel unstable at speed. The Polyair Bellows airbag kit fixes all of it.
Polyair Bellows Kit for the N90 HiLux
The Polyair Bellows Kit installs between the chassis and the leaf springs on the N90 HiLux, adding a pneumatic support system that is fully adjustable from 5 to 100 PSI. When you add your weight, pump up the pressure until the rear sits level. When you unload, bleed the pressure back down and the HiLux rides exactly as it did from the factory.
It's a bolt-in installation: no welding, cutting or permanent changes to the vehicle.
This is the same bellows technology Polyair has relied on for many decades, now purpose-built and vehicle-specific for the N90 HiLux platform.
Two N90 Hilux Airbag Kit Options Available
The Polyair Bellows Kit for the N90 HiLux is available in two configurations to suit both standard and lifted vehicles.
Standard Height Kit
The standard height N90 Hilux airbag kit suits vehicles running factory ride height. Bolt-in fitment, 5–100 PSI adjustability, and full load support without altering the vehicle's geometry.
Shop Standard Kit2-Inch Raised Kit
The 2-inch raised N90 Hilux airbag kit is designed for vehicles running a 2-inch suspension lift. Engineered to work correctly at the raised ride height while still delivering the full range of load support.

If your N90 HiLux has been lifted and regularly sees off-road use, consider adding the Polyair Cradle Kit to your order. The cradle allows the bellows to separate from its bracket and allow full suspension droop. Super essential for traction when off-road.
It is a straightforward addition that makes a real difference for HiLux owners who head off the beaten track. The bellows does its job under weight on the road, and the cradle takes care of it when the suspension is working hard off-road.
