Build Quality:
Each BOSS airbag is built using natural rubber, high-tensile steel, and ballistic-woven reinforcements, then cured under high pressure and heat for durability.
Easy Installation:
Most kits bolt on using basic hand tools. Once inflated, the airbags level the rear of your vehicle under load.
Proven Reliability:
BOSS has decades of experience in air suspension, with tens of thousands of kits installed worldwide—in everything from 4WDs and motorhomes to mining vehicles and farm equipment. Our gear is field-tested in extreme environments from the Australian outback to Canadian winters.
Tip for Best Use:
Inflate the airbags just enough to bring your vehicle back to level. This helps distribute weight evenly across all suspension components, preventing strain on any single part.
