Frequently asked questions

What is the difference between 2400, 2500 and 2600 series Boss airbags?

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.

When should I use a triple-bellow airbag like a 2503 or 2603?

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.

Can I mix and match different airbag series in my existing kit?

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.

What pressures are Boss airbags designed to handle?

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.

How should I mount and protect a replacement airbag?

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.

What is the load capacity of the Boss Airbag 2500 Bare?

The Boss Airbag 2500 Bare has a load capacity of 2500lb or 1136kg at 100psi. This makes it suitable for assisting with load management in various applications.

Can the Boss Airbag 2500 Bare be used as a replacement for worn-out airbags?

Yes, the Boss Airbag 2500 Bare is designed to replace worn-out airbags in Load Assist kits, providing a reliable solution for maintaining vehicle stability and load support.

What lift range is the Boss Airbag 2500 Bare suitable for?

The Boss Airbag 2500 Bare is typically suited for standard height applications and can accommodate lifts of up to approximately 2 inches when used with appropriate brackets or spacers.

What type of mounting rings are included with the Boss Airbag 2500 Bare?

The Boss Airbag 2500 Bare comes with rings specifically designed for mounting to Boss Load Assist Kits, ensuring a secure and reliable fit for your suspension system.
