Understanding - Airbag Suspension / Load Carrying

Load carrying airbags, offered by companies like Airbag Man, are a valuable upgrade for 4WD or commercial vehicles that frequently carry heavy loads or tow trailers. This guide will help you understand the importance of installing load carrying airbags on your 4WD or commercial vehicle and how they can significantly improve your driving experience, safety, and vehicle longevity.

Understanding Load Carrying Airbags

Load carrying airbags are supplemental suspension components that can be installed on a vehicle's rear axle or between the frame and the suspension. They are designed to provide additional support and stability when carrying heavy loads or towing. These airbags are adjustable, allowing you to fine-tune the air pressure within the airbag to match the load you are carrying, ensuring optimal performance and comfort.

Importance of Installing Load Carrying Airbags on a 4WD or Commercial Vehicle

  1. Improved Load Carrying Capacity: One of the primary benefits of load carrying airbags is their ability to enhance your vehicle's load carrying capacity. By providing additional support to the vehicle's suspension, airbags help maintain a level ride height even when carrying heavy loads or towing, ensuring optimal handling, stability, and comfort.

  2. Reduced Suspension Sag and Vehicle Sway: Heavy loads can cause suspension sag, which can negatively impact vehicle handling and increase the risk of bottoming out. Load carrying airbags help to reduce suspension sag and minimize vehicle sway, improving handling, stability, and safety when driving with heavy loads.

  3. Enhanced Ride Comfort: Load carrying airbags can help to smooth out the ride, providing enhanced comfort when driving with heavy loads or towing. By adjusting the air pressure in the airbags, you can fine-tune the suspension to achieve the desired level of support and comfort.

  4. Reduced Stress on Suspension Components: Heavy loads can put excessive strain on your vehicle's suspension components, leading to premature wear and potential damage. By providing additional support, load carrying airbags help to reduce stress on your vehicle's suspension components, prolonging their lifespan and reducing maintenance costs.

  5. Increased Towing Stability: Load carrying airbags help to maintain optimal suspension geometry and stability when towing, which is essential for safe and controlled towing. This increased stability can be particularly beneficial when towing heavy trailers, caravans, or boats.

Selecting and Installing Load Carrying Airbags for Your 4WD or Commercial Vehicle

When choosing load carrying airbags for your vehicle, consider the following factors:

  1. Vehicle Compatibility: Ensure that the airbag system you choose is compatible with your vehicle's make, model, and suspension setup. Consult with the airbag manufacturer or a suspension specialist for guidance.

  2. Load Capacity and Usage: Consider your vehicle's typical load capacity and usage when selecting a load carrying airbag system. This will help you choose a system that provides the appropriate level of support and adjustability for your specific needs.

  3. Installation and Maintenance: Load carrying airbags should be installed by a qualified professional or an experienced DIYer with the appropriate tools and knowledge. Regular maintenance, including checking air pressure and inspecting the airbags for damage or leaks, is essential to ensure optimal performance and longevity.


Installing load carrying airbags on a 4WD or commercial vehicle can provide significant benefits in terms of load capacity, handling, ride comfort, and suspension component longevity. By offering additional support and adjustability, load carrying airbags help to maintain optimal vehicle performance and safety when carrying heavy loads or towing. Regular checks and adjustments are essential to maximize the benefits of your upgraded suspension system.
