Boss Airbag 2403 Triple Bellows Bare

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 2403 TRIPLE AIRBAG is designed for vehicles with a lift range of over 2 inches. It is ideal for setups requiring additional travel and support, making it suitable for lifted vehicles or those with heavy loads.

While the 2403 TRIPLE AIRBAG is primarily designed for vehicles with lifts over 2 inches, it can also be used with standard height vehicles if paired with appropriate brackets or spacers to ensure proper fitment and performance.

The 2403 TRIPLE AIRBAG is commonly used in applications where enhanced load support is needed, such as towing heavy trailers, carrying heavy loads in utes, or improving ride quality in lifted vehicles. It is ideal for both work and recreational use.

Yes, the 2403 TRIPLE AIRBAG is designed to work alongside existing leaf springs. It does not replace the suspension but rather enhances it by providing additional support and stability, ensuring the vehicle sits correctly when loaded.

Regular maintenance for the 2403 TRIPLE AIRBAG includes checking for leaks, ensuring proper air pressure, and periodic visual inspections for any signs of wear or damage. It is also recommended to drain the air system to remove moisture periodically.
