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 recommended gap between the axle and the top mounting point for this kit? ⌄

The ideal gap between the axle and the top mounting point is around 200mm. If your setup does not accommodate this gap, please contact us for assistance in developing a suitable solution.

What is the weight rating of the Boss Extreme Series airbags included in this kit? ⌄

The Boss Extreme Series airbags are rated at 2500lb or 1136kg per side. They have been tested and approved to withstand pressures exceeding 750psi, ensuring durability and reliability.

How should I adjust the air pressure in the airbags for optimal performance? ⌄

For optimal performance, inflate the airbags just enough to achieve a level ride height. This allows the suspension components to share the load evenly, preventing excessive pressure on any single part of the suspension system.

How does this kit compare to other airbag options? ⌄

This kit features Boss Extreme Series airbags, which are specifically designed for high durability and performance. Unlike some unbranded options, our airbags are manufactured in-house and tested rigorously. This ensures reliability and longevity, making them suitable for a wide range of applications, from 4WDs to trailers and motorhomes.
