Boss Airbag 2403 Triple Bellows 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 2403 is designed for applications requiring up to 2 inches of lift. For lifts exceeding this height, consider using taller brackets or spacers in conjunction with the triple-bellow design.

The 2403 features a triple-bellow design, providing greater travel and load capacity compared to double-bellow options like the 2400 or 2500 series. This makes it ideal for vehicles that require more suspension travel or have higher load demands.

The maximum working pressure for the Boss Airbag 2403 is 160psi, with a test pressure of 480psi and a burst pressure of 750psi, ensuring robust performance under demanding conditions.

The Boss Airbag 2403 is designed for specific applications and may not be universally compatible. Always check your vehicle's specifications and consult with Boss for fitment guidance to ensure proper installation.

Yes, the Boss Airbag 2403 is suitable for off-road applications, providing enhanced stability and load support on uneven terrain. Its robust construction and triple-bellow design make it ideal for demanding conditions.
