Boss Extreme series airbags are rated at 2600lb or 1181kgper side and have been government approved tested to over 750psi.

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

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 unnecessary pressure on any one individual part of your vehicles suspension.
