Boss Airbag 2400 Complete

The 2400, 2500 and 2600 series are all double-bellow Boss airbags in different diameters and load capacities. 2400 bags are smaller in diameter, 2500 are the most common mid-size bag used in many Load Assist kits, and 2600 bags are larger and suit heavier-duty applications where there is more space available around the axle and chassis.

Triple-bellow airbags such as the 2503 and 2603 are used where you need more travel or a taller free height, typically on vehicles with more than 2 inches of lift or long-travel suspension. They allow the suspension to sit higher at a given pressure while still providing the correct load support.

No, airbags are generally only interchangeable within the same series. For example, a 2500 double-bellow bag can often be swapped for a 2503 triple-bellow bag in a kit designed for that series, but you cannot simply fit a 2600 or 2400 into 2500 brackets. The bracket diameter, bolt pattern and clearances are all designed around a specific series.

Boss airbags typically have a recommended working range of around 5–160 psi, with a recommended test pressure of about three times the maximum working pressure and burst testing well above that. Always refer to the specific bag’s data and never exceed the recommended working pressure in normal use.

Replacement airbags must be installed on the correct brackets with the correct beadlock rings or hardware as designed for that kit. Ensure there is adequate clearance from tyres, exhausts, sharp edges and moving suspension parts, and maintain minimum pressure so the bag does not fold or pinch under full compression or articulation.

The Boss Airbag 2400 features a robust design with a maximum working pressure of 160psi and a burst pressure of 600psi, which is higher than many competitors. Its beadlock-style clamping ring ensures superior durability, preventing separation under extreme conditions.

Yes, the Boss Airbag 2400 is suitable for off-road applications, providing enhanced stability and load support on uneven terrain. However, ensure that the installation is done correctly to prevent air transfer between bags, which can affect performance.

Yes, the Boss Airbag 2400 can be used in tandem axle setups. It is recommended to link the airbags on the same side to maintain stability and level the trailer or caravan when traversing uneven surfaces.
