Boss Extreme Series Airbags – For Vehicles with Rear Suspension Lift (1-2 Inches)
Take your vehicle’s suspension to the next level with Boss Extreme Series airbags, built for tough loads. Rated at 2500lb (1136kg) per side and government-approved for testing over 750psi, these airbags are designed to handle the demands of off-road and heavy-duty use. Manufactured and branded by Boss, you’re getting quality you can trust, unlike unbranded imports.
Ideal for vehicles with a pre-fitted rear suspension lift of 1-2 inches, these airbags provide excellent support for most dual cab utes running between 15-45psi depending on load. Boss has sold over 13,000 load assist kits in Australia, earning trust from 4WD enthusiasts, miners, tradies, and tour operators. They’re also perfect for agricultural vehicles, trailers, and motorhomes.
For best performance, inflate the airbags just enough to level your ride height, ensuring the load is evenly distributed across your suspension system and reducing wear on individual components.
NOTE: Only suits vehicles with a pre-fitted rear suspension lift of 1-2 inches.
We're Australians, and we like to support our fellow Australians, which is why all our products are sourced locally from the official Australian distributors.
