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.
