Polyair Standard/Raised Height Ultimate Airbag Kit
Includes:
1x Polyair Ultimate Airbag Kit - 88288ULT / 88388ULT
Details:
- Air adjustable from 5-100psi
- Internal Bumpstop
- Built with a superior 2-ply fabric reinforced rubber
- Ultra high strength & corrosion proof Zytel ® Nylon end caps
- Easy to install with illustrated instructions
- Quick connecting, easy to use air fittings.
- Bespoke design for each vehicle
- Position: Rear
More Information:
The Polyair Airbag kits are specifically designed to suit leaf sprung vehicles.
When you load up the back of the vehicle or hook up a caravan / trailer, you’ll notice the rear end drop down, this drop in height can have some adverse effects on your vehicle’s safety and handling, with symptoms such as:
- Suspension bottoming out
- Rough ride
- Excessive sway & body roll
- Unpredictable braking characteristics
- Poor headlight aim
- Clearance issues
All this can be mitigated by installing a set of Polyair Airbags.
The Airbag kit is air adjustable giving you flexibility to tailor the level of support for your individual load types and weights. Having a correctly sprung vehicle for constant loads is always recommended as the first step, but in most cases the leaf springs are rated well past what you will carry daily, giving you a rough, uncomfortable ride when not loaded up.
Having the flexibility of the adjustable Polyair Airbags means you can have a smooth stock ride comfort when unloaded and simply adjust the pressure when towing or hauling. Simple.
Polyair Airbag Cradle Kit
Includes:
1x Airbag Cradle Kit - ABCUSA
Details:
The Polyair ‘Cradle Kits’ are the perfect solution for lifted 4×4’s that like to load up and head off-road. The Cradles are compatible with any of our Airbags kits for raised leaf spring vehicles.

- The Cradle Kit is designed for vehicles with minimum 1″ Suspension lift.
- More grip off road, load levelling on road. The best of both worlds!
- Fits all Polyair Airbags kits
- Allows full extension of the vehicle's suspension
- Made from durable & lightweight resin
