LOAD LEVELLING -Heavy loads and trailer towing often cause sag, sway and bottoming out. At night road visibility becomes impaired because headlight aim is pointing to the sky. Polyairs cure these problems by boosting overload support and maintaining proper ride height, making driving safer

RENEWS SPRING LIFE -Springs don’t have to be old and worn to be tired. Polyair Springs eliminate the need to replace weakened springs by putting life back into them and enhancing them with the air adjustable feature.

IMPROVES OFF ROAD PERFORMANCE -Driving on rugged terrain results in constant and severe pounding action to the springs. Polyairs boost spring rates to help prevent bottoming and absorbs those hard impacts. With the air adjustable features, springs can quickly be adjusted for on or off road use.

CORNERING / HANDLING -Polyairs increase cornering and handling performance by reducing body roll and sway. The air adjustable feature permits modification of spring rates to the drivers personal ride preference.



Polyair Springs have been providing load levelling solutions to the Australasian region since the late 1950s. Starting as a 1 man operation, the product has gained popularity through its wide range of benefits, and value for money.

The airbag in coil concept originated with NASCAR in 1949. On the unrelenting banked circuits, weight distribution was found to be a key factor in optimising handling. The capabilities of the air bags was soon put to use on road going vehicles.

Through the 1950’s the product gained popularity, and was developed even further. By the 1980s the product became a common site on motorhomes, ambulances, load bearing pick up trucks etc.

In Australia at the beginning of the 1980’s a well established steering and suspension business recognised the significance of Polyair Springs. The directors bought the locally grown company, with the aim of developing the brand further.

Since then they have been a leading name in the air bag industry.

Sales growth has enabled Polyair Springs to keep pace with greater demand, developing products for the ever growing range of vehicles on the road.

All of their kits are developed on site by their R&D engineers, who have a keen understanding of the challenging industrial and recreational environments the products are subject to.
