Load Assist Kit for Fiat Ducato ( Low Rider option)

No. A Boss Load Assist kit does not increase your GVM. It supports and levels the vehicle within the factory limits so it sits and tows correctly, but the legal carrying capacity is still set by the vehicle’s original GVM and rear axle ratings.

On vehicles, Boss Load Assist kits are plumbed as a dual-path system so the left and right airbags cannot transfer air between them. This stops the vehicle leaning or feeling unstable in corners. Linking left and right together allows air to move from the loaded side to the unloaded side, which can cause body roll and poor handling.

Yes, but the setup depends on your lift height. Standard 2500 or 2600 double-bellow bags work on stock height and lifts up to around 2 inches. For more than 2 inches of lift you generally need triple-bellow bags (2503 or 2603) and/or different brackets or spacers. The best approach is to measure the gap at the bump stop at your desired ride height and confirm the correct kit with Boss.

LA Clearance kits are standard Boss Load Assist kits that may have minor cosmetic marks, small scratches or packaging damage. The structural components, testing, performance and warranty are the same as the non-clearance kits. They are simply offered at a sharper price because they are not cosmetically perfect.

Yes, provided you stay within the same airbag series. For example, if your kit uses 2500 airbags and you add more than 2 inches of lift, you can normally upgrade to 2503 triple-bellow bags that suit the same bracket pattern. Airbags from different diameter series (e.g. 2400 vs 2500 vs 2600) are not interchangeable unless the kit is specifically designed for that change.

Boss airbags are manufactured using a proprietary blend of cured natural rubber, hi-tensile steel cords and ballistic reinforcing. They are independently tested to a recommended test pressure around three times the maximum working pressure, and burst-tested even higher. In load assist applications it is virtually impossible to pull the bag apart from the bracket because the bead is clamped by a solid aluminium ring, rather than relying on crimped plugs.

Boss airbags are attached to the mounting brackets using an aluminium clamping ring that acts like a beadlock. The ring clamps the bead of the airbag directly to the steel plate so the bag is mechanically locked in place. Many other brands, including big names like Firestone and Dunlop, use plastic or metal end plugs crimped into the bellows. Under extreme droop (for example on a hoist or heavy articulation), those plugs can be pulled out of the bag. With the Boss beadlock-style design, the bag cannot be pulled off the mounting plate in normal service.

Most competent DIYers can install a Boss Load Assist kit with basic tools in 2–3 hours. The brackets are vehicle-specific and generally bolt to existing chassis points. You need to be comfortable working safely under the vehicle, routing airlines away from heat and moving parts, and setting basic alignment. If in doubt, a suspension or 4x4 workshop can fit the kit for you.

Do not run the bags completely empty. A minimum of around 5–10 psi is recommended when the vehicle is unladen. This keeps the bag in shape and protects it from pinching or chafing under full articulation.

The Boss Extreme Series 2500 airbags included in this kit are rated at 2600lb or 1186kg per side. This rating ensures that your Fiat Ducato can handle significant loads while maintaining stability and comfort.

For the Load Assist Kit to fit properly, there must be a gap of close to 187mm between the top of the leaf spring and the underside of the chassis rail when the vehicle is at level ride height. If your vehicle measures around 235mm, consider the alternative kit SKU LA-66.

This Load Assist Kit is designed for standard height and up to approximately 2 inches of lift. For lifts greater than this, you may need to consider using the triple-bellow airbags or additional spacers to accommodate the increased height.

To achieve the best performance from your Load Assist Kit, inflate the airbags just enough to achieve a level ride height. This allows all suspension components to share the load evenly, preventing unnecessary pressure on any single part of your vehicle's suspension.

For an average dual cab ute, the typical air pressure range in the airbags is between 15-45psi, depending on the load being carried. Adjusting within this range will help maintain vehicle stability and comfort.

Boss airbags are manufactured in-house and are branded Boss, ensuring quality and reliability. Unbranded airbags, often sourced from other companies in China, may not meet the same rigorous testing and quality standards, which can affect performance and safety.

Yes, the Load Assist Kit for the Fiat Ducato is ideal for towing as it helps to level and stabilise the vehicle, ensuring it sits correctly while towing. This enhances safety and handling, particularly when carrying heavy loads.
