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 BAG-4500 COMP air bags are designed to accommodate a lift range of up to 2 inches. For lifts greater than 2 inches, it is recommended to pair these bags with taller brackets or consider using triple-bellow options for enhanced performance.

The BAG-4500 COMP is suitable for a variety of vehicles that require load assistance. It is essential to verify compatibility with your specific make and model. Always consult with Boss Air Suspension for the best fitment advice.

The BAG-4500 COMP features a robust design that provides superior support compared to standard air bags. It is specifically engineered for heavy-duty applications, making it suitable for vehicles that frequently carry heavy loads or require additional stability.

The BAG-4500 COMP air bags are tested to withstand a maximum working pressure of 100 psi, ensuring they provide reliable performance under load. Always adhere to the recommended pressure settings for optimal operation.

While the BAG-4500 COMP can be used independently, it is recommended to pair it with appropriate brackets and a compressor for a complete Load Assist kit. This ensures optimal performance and ease of installation.

To maintain the BAG-4500 COMP air bags, regularly check for leaks and ensure the air pressure is within the recommended range. Additionally, periodically inspect the bags for any signs of wear or damage, and drain any moisture from the system to prevent corrosion.
