Boss Extreme series airbags are rated at 2500lb or 1136kg per side and have been government approved tested to over 750psi.

All Boss airbags are manufactured by us and are branded Boss. Beware of unbranded airbags, usually coming from China from other companies.

Average dual cab ute will run around 15-45psi depending on load.

Boss has sold over 13000 load assist kits in Australia, proven over time with 4WD enthusiasts, Mining companies, Tradies, 4WD Tour Operators as well as in Agricultural Vehicles, Trailers and motorhomes, limited only to your imagination.

To get the best performance from your kit inflate airbags just enough to achieve a level ride height. By doing this you are also allowing all of the suspension components to share the extra load of the vehicle and not putting any unecessary pressure on any one individual part of your vehicles suspension.

If you carry heavy loads heavier springs have been the answer for years. But heavy springs also bring the disadvantage of a harsh ride and poor handling when the vehicle is unloaded or lightly loaded. If your load varies you need a suspension system that can be varied to suit the conditions and load at hand.

BOSS Air Bag Load Assist kits have the advantage of being able to be run practically undeflated when your vehicle is unladen or with a light load (although 2-5PSI is recommended and can be adjusted to help remove body roll from the vehicle). The airbags can then be inflated to suit the load at hand as required. The heavier the load the more air you can apply. Realistically you only need 20 to 40 psi but the bags are tested to 400 psi during quality. Boss Air suspension systems are precision engineered and capable of exceeding your load carrying expectations by a long way.
