Airbag Suspension for Tradies Work Utes & 4x4's

Stop Ute Sag. Carry Your Work Load Safely with Confidence.

Your ute works hard every day. Toolboxes, canopies, service bodies, drawers, tools and equipment can place a constant load over the rear suspension, causing the back of your ute to sit lower than it should.

THOR Air Suspension Load Assist Kits provide adjustable rear suspension support to help level your ute when carrying heavy or uneven loads.

Whether you're an electrician, plumber, builder, mechanic, refrigeration technician, landscaper or mobile service technician, THOR gives you the flexibility to adjust your suspension support to suit the load you're carrying.

Built for work. Built for Australian conditions. Built by THOR.

Is Your Work Ute Sagging Under Load?

A work ute can accumulate a surprising amount of permanent weight.

A canopy, drawers, shelving, tools, batteries, spare parts, compressors, water tanks and other equipment can place hundreds of kilograms over the rear suspension before you've even loaded materials for the day's job.

Common signs your ute may need additional load support include:

Rear suspension sag
Nose-up vehicle stance
Headlights pointing too high at night
Increased body roll or sway
Reduced stability when heavily loaded
Suspension bottoming out over bumps
Uneven loads causing the vehicle to sit lower on one side

THOR Load Assist Airbags work with your vehicle's existing suspension to provide additional adjustable support when it's needed.

Why Airbags Make Sense for a Work Ute

Unlike a fixed suspension change, airbag suspension support can be adjusted according to the load you're carrying.

Running light today? Reduce the air pressure.

Fully loaded with tools and equipment tomorrow? Increase the pressure to provide additional support.

This makes load-assist airbags particularly useful for work vehicles where loads can change from one day to the next.

Benefits of THOR Load Assist Airbags

Helps restore vehicle ride height when loaded
Reduces rear suspension sag
Provides adjustable support for changing loads
Helps improve stability and vehicle control
Reduces body roll and sway
Helps maintain correct headlight alignment
Supports uneven left-to-right loads
Works with your existing suspension
Ideal for permanently or regularly loaded work vehicles

Important: Load-assist airbags do not increase your vehicle's legal GVM, axle capacity or payload rating. Your vehicle must always remain within the manufacturer's specified limits.

Built for Tradies Who Carry Real Loads

Electricians

Service bodies, cable, batteries, ladders, tools, drawers and electrical equipment can create substantial permanent weight.

THOR airbags allow additional rear suspension support to be added when your ute is loaded for work.

Plumbers

Pipe fittings, pumps, tools, materials, roof racks and service bodies can quickly add weight to the rear of a ute.

Adjustable airbags help support the suspension and restore a more level vehicle stance under load.

Builders & Carpenters

Toolboxes, saws, compressors, fixings and building materials mean your load can change constantly.

Airbags allow you to adjust suspension support depending on what you're carrying.

Mobile Mechanics & Service Vehicles

Mechanics' utes can carry some of the heaviest permanent setups, including service bodies, tools, spare parts, batteries, compressors and recovery equipment.

THOR Load Assist Kits are well suited to vehicles carrying significant constant loads.

Refrigeration & Air Conditioning

Shelving, tools, refrigeration equipment, gas bottles and spare parts can create both heavy and uneven loads.

Independently inflated airbags can help compensate for uneven weight distribution between the left and right sides of the vehicle.

Fleet & Commercial Vehicles

Running multiple work utes?

THOR can supply load-assist airbag suspension for a wide range of Australian fleet and commercial vehicles.

Australian-Made Strength Where It Matters

THOR has been developing air suspension products for Australian vehicles for years.

Our Load Assist Kits are engineered around the vehicle rather than simply supplying an airbag and expecting it to fit.

THOR kits feature heavy-duty air bellows combined with vehicle-specific mounting hardware designed to provide reliable suspension support in demanding work applications.

Our current kits include:

Heavy-duty 2500 lb double-convoluted airbags
Australian-made 6 mm steel mounting brackets
Heavy-duty mounting hardware
1/4" airline
Push-connect Schrader inflation valves
Stainless steel mounting panel
Vehicle-specific installation instructions
THOR warranty support

Most THOR Load Assist Kits are designed for straightforward bolt-on installation using basic hand tools, although installation requirements vary between vehicles.

Add On-Board Air Control

Want to adjust your airbags without getting out of the ute?

Add a THOR On-Board Air Control System and adjust your airbag pressure from inside the vehicle.

This is particularly useful for work utes where loads regularly change.

Carry tools during the week, unload equipment, add materials or change the weight distribution — then adjust your air pressure to suit.

Constant Load Doesn't Always Mean You Need Stiffer Springs

Heavy-duty springs can be suitable for vehicles carrying a substantial permanent load, but not every work ute carries exactly the same weight every day.

That's where adjustable airbag suspension can be useful.

Airbags allow you to vary the amount of additional suspension support according to the load.

For vehicles that alternate between lighter and heavier loads, this gives you considerably more flexibility than a fixed suspension setup alone.

Airbags can also be used alongside suitable existing suspension where additional load levelling is required.

Frequently Asked Questions

Are airbags good for work utes?

Load-assist airbags can be particularly useful on work utes carrying constant or changing loads. They provide adjustable support to the existing rear suspension and can help restore vehicle ride height when loaded.

Will airbags increase my ute's payload or GVM?

No. Airbags do not increase the manufacturer's legal payload, GVM or axle ratings. They provide suspension support within the vehicle's existing legal load limits.

Can airbags help a ute with a heavy canopy?

Yes. A canopy combined with drawers, tools and equipment can create significant permanent rear weight. Load-assist airbags can provide additional adjustable suspension support to help compensate for this load.

Are airbags suitable for a service body?

They can be. The correct setup depends on the vehicle, service body and total weight being carried. Always ensure the vehicle remains within its legal GVM and axle limits.

Can I adjust each airbag separately?

On suitable installations, the left and right airbags can be inflated independently. This can be particularly useful for work vehicles carrying more equipment on one side than the other.

Do I need an air compressor?

No. THOR Load Assist Kits can be inflated through Schrader valves using a suitable external air source. An optional on-board compressor and control system can be added for convenient adjustment from the vehicle.

Can I install a THOR kit myself?

Most THOR Load Assist Kits are designed for bolt-on installation using basic hand tools. Installation requirements vary depending on the vehicle, so always check the instructions for your specific kit.
