Frequently asked questions

Why fit airbags to a trailer or caravan?

Airbags on trailers and caravans are commonly used to lower the deck for easier loading and unloading, and to level the trailer on uneven ground when parked. They can also improve ride quality and help protect the trailer and its contents from harsh bumps.

How are airbags typically plumbed on tandem-axle trailers?

On tandem-axle trailers it is common to connect the front and rear airbags on the same side together, while keeping the left and right sides separate. When the front wheel on a side goes over a bump, air moves to the rear bag, pushing that wheel down as it follows over the bump. This keeps the trailer more level over rough surfaces. Side-to-side linking is avoided as it can upset stability.

What is the maximum load capacity of the Airbagged Trailer Kit Round Axle 2500?

The Boss Extreme Series Double Bellow Airbags in this kit are rated at 2500lb or 1136kg per side. This means you can effectively support a total load of up to 5000lb or 2272kg when both airbags are utilised.

What is the recommended air pressure range for optimal performance?

For an average dual cab ute, the recommended air pressure range is typically between 15-45psi depending on the load being carried. Adjust the pressure to achieve a level ride height for best performance.

Can this kit be used on trailers with different axle configurations?

This kit is specifically designed for trailers with a round axle and square chassis. For other axle configurations, different kits may be required to ensure proper fitment and performance.

How does the installation process work for this kit?

The kit comes with detailed instructions for fitting. It includes 4 brackets (2 upper and 2 lower) and mounting hardware, making installation straightforward for those with basic mechanical skills.

What are the benefits of using this airbag kit on my trailer?

Using the Airbagged Trailer Kit Round Axle 2500 allows for better load distribution, improved stability, and the ability to level the trailer when parked on uneven surfaces. This enhances safety and ease of loading/unloading.

Are the airbags in this kit interchangeable with other brands?

No, the airbags in this kit are specifically designed and manufactured by Boss. They are not interchangeable with other brands, ensuring compatibility and reliability in performance.

How often should I check and maintain the air pressure in the airbags?

It is recommended to check the air pressure in the airbags regularly, especially before long trips or when loading the trailer. Maintaining the correct pressure ensures optimal performance and safety.
