Tradie vans and work utes carry inconsistent loads every day — tools and stock one trip, empty tray the next — and that swing in weight changes rear ride height enough to affect headlight aim, braking and stability. This guide ranks the load assist airbag kits worth fitting to common Australian work vehicles in 2026, based on how each vehicle type is actually used on the job.
- Best overall airbag kit for tradie vans in 2026: the Toyota HiAce load assist kit, built for daily payload swings without changing ride height at rest.
- Best for large cargo vans hauling tools and stock: the Ford Transit load assist kit, suited to vans that run heavy most working days.
- Best budget-friendly option: the LDV G10 load assist kit, matched to smaller trade vans carrying lighter but regular loads.
- Every load assist airbag kit here works with the vehicle's existing suspension — none change the legal GVM or payload rating.
- Air pressure adjusts from empty to full load, so one Boss Air Suspension load assist kit covers the whole working week.
Why this matters
A work van or ute sitting low at the rear under load isn't just uncomfortable — it changes how the vehicle handles, brakes and steers. Headlights point up into oncoming traffic, tyre wear becomes uneven, and the standard leaf or coil suspension is doing more work than it was designed for.
A load assist airbag kit sits inside the existing suspension and adjusts with air pressure to help support that extra weight. It doesn't lift the vehicle's rated payload or GVM — it helps the suspension carry the load it's already rated for more evenly, which is why fitment and correct pressure matter more than raw airbag size.
What makes the best airbag kit for tradie vans
- Vehicle-specific fitment — brackets and mounting points matched to the exact chassis, axle and suspension type, not a generic clamp-on fit
- Load range suited to daily use — sized for regular tool and equipment weight, not occasional touring loads
- Air pressure adjustability — easy to wind pressure down for an empty run and back up for a full load
- Straightforward installation — bolt-on brackets that don't require drilling into the chassis on most applications
- Compatibility with the existing suspension — works with the factory leaf spring or coil setup rather than replacing it
- Warranty and local support — parts and technical backup available in Australia when something needs checking

1. Toyota HiAce: best airbag kit for daily parcel and trade delivery runs
The HiAce is one of the most common delivery and trade vans on Australian roads, and it's usually loaded and unloaded multiple times a day. A Toyota HiAce load assist kit is designed to work with the van's existing rear suspension, helping it hold a more level ride height as weight comes on and off through the day.
Toyota HiAce pros:
- Bolt-on brackets suit most factory HiAce configurations
- Air pressure can be adjusted quickly between loaded and empty runs
- Backed by a five-year warranty through Boss Air Suspension
Toyota HiAce cons:
- Not intended to replace heavy-duty suspension work for constant maximum loads
- Correct fitment depends on confirming the exact HiAce model and year
Best for: delivery drivers and tradies who load and unload the same van several times a day.
Verdict: Buy — the most practical match for a van that rarely sits at one fixed weight.
2. Ford Transit: best airbag kit for large cargo vans with heavy tool loads
The Transit's larger cargo bay means it's often carrying more weight than a HiAce or Transporter on a typical day, particularly for trades running racking, shelving and stock. A Ford Transit load assist kit is built to help the rear suspension manage that consistent extra weight.
Ford Transit pros:
- Suited to vans that run heavy most working days, not just occasionally
- Works with the factory suspension rather than requiring a full suspension swap
- Straightforward bolt-on installation on most Transit configurations
Ford Transit cons:
- Larger van body means more time required for a correct install
- Heavier fitouts should still be checked against the van's rated GVM
Best for: trades running a fully racked-out Transit that's rarely driven empty.
Verdict: Buy — a sound match for vans carrying consistent daily weight.
3. Volkswagen Crafter and Transporter: best airbag kit for vans running roof racks and ladder racks
Roof-mounted ladders, racking and equipment shift weight higher and further back than a floor-loaded van, which changes how the rear end sits. A Volkswagen Crafter and Transporter load assist kit is designed to help manage that rear-end sag alongside the roof load.
Volkswagen Crafter / Transporter pros:
- Addresses sag caused by roof-mounted equipment, not just floor load
- Adjustable air pressure suits a van that changes load through the week
- Vehicle-specific bracket kit for a cleaner install
Volkswagen Crafter / Transporter cons:
- Roof rack load still needs to stay within the vehicle's own rated limit
- Not a substitute for checking overall vehicle weight before loading
Best for: tradies who run roof racks or ladder racks as a permanent fixture.
Verdict: Buy — worth fitting if roof-mounted gear is a daily feature, not an occasional extra.
4. Mercedes Sprinter: best airbag kit for mobile workshop and fitout vans
Sprinters fitted out as mobile workshops, service vans or mobile trade units carry a fixed, heavy load that doesn't change much day to day. A load assist kit here is less about adjusting for varying weight and more about supporting a consistently loaded rear end.
Mercedes Sprinter pros:
- Suited to vans carrying a fixed fitout weight rather than fluctuating loads
- Works alongside the factory suspension without major modification
- Available for a range of Sprinter configurations
Mercedes Sprinter cons:
- Fitout weight should be confirmed against the vehicle's GVM before fitting
- Less benefit for Sprinters that run mostly empty between jobs
Best for: mobile workshop and fitout vans carrying a permanent heavy load.
Verdict: Buy — a good match once the fitout weight is confirmed as within the vehicle's rating.
5. Single cab work utes: best airbag kit for tray-mounted equipment and toolboxes
Single cab utes running a steel tray, toolboxes and site equipment often carry weight concentrated over the rear axle. An airbag kit for single cab work utes is built to support that rear-end loading pattern directly.
Single cab ute pros:
- Direct support under a loaded tray, where the weight actually sits
- Bolt-on brackets suit most factory tray and chassis setups
- Adjustable pressure for jobs that vary in equipment weight
Single cab ute cons:
- Tray design varies between builders, so fitment should be confirmed
- Not designed to alter the ute's rated payload capacity
Best for: tradies running a fixed tray with regular toolbox and equipment weight.
Verdict: Buy — a solid fit for the classic tray-and-toolbox work ute.
6. Dual cab utes with canopy or tray: best airbag kit for tradies carrying crew and gear
A dual cab running a canopy or service body carries passenger weight up front and equipment weight out back, which adds up quickly on a loaded job site run. A load assist kit for this setup is built to manage the combined rear-end load rather than crew weight alone.
Dual cab canopy/tray pros:
- Handles combined passenger and equipment weight without excessive sag
- Works with the ute's existing leaf spring or coil suspension
- Adjustable pressure suits crews that don't always run at full capacity
Dual cab canopy/tray cons:
- Canopy weight adds to what the kit needs to manage, so total load matters
- Fitment can vary depending on the canopy or service body brand
Best for: crews running a canopy or service body with regular passenger and equipment weight.
Verdict: Buy — worth it once canopy and crew weight are regularly pushing the rear end down.
7. LDV G10: best airbag kit for smaller trade vans on a budget
The LDV G10 is a smaller van used by trades that don't need the cargo capacity of a HiAce or Transit but still carry regular tool and equipment weight. A load assist kit here is a simpler, lighter-duty option matched to that smaller platform.
LDV G10 pros:
- Bolt-on kit suited to a smaller van platform
- Adjustable pressure for lighter but regular daily loads
- A more accessible entry point for trades on a tighter budget
LDV G10 cons:
- Not intended for heavy daily payloads beyond the van's normal use case
- Smaller load range than kits built for the HiAce or Transit
Best for: smaller trade vans carrying light-to-moderate loads on a regular basis.
Verdict: Buy — a sensible pick if the G10's smaller cargo area still gets loaded most days.
How we ranked
Each kit was assessed against the same criteria: vehicle-specific fitment, whether the load range matches how the vehicle is actually used, ease of installation, air pressure adjustability, compatibility with the existing suspension, and warranty support. Vans and utes that carry heavy, consistent daily loads score differently to those used for lighter, occasional weight — which is why this list separates use cases rather than ranking every vehicle against a single benchmark.
“If the rear end sags noticeably every time the tray or van is loaded, that's the signal to look at load assist, not just tyre pressure.”
Featured load assist kits
Which airbag kit should you choose?
For most tradie vans doing multiple loaded and unloaded runs a day, the Toyota HiAce load assist kit is the default recommendation for 2026 — it's built around the exact problem most delivery and trade vans face. If the van or ute carries heavy tools and stock most of the working day, step up to the Ford Transit load assist kit or the equivalent for a similarly large van. Running a smaller van on a tighter budget points to the LDV G10 load assist kit instead.
Whatever the vehicle, confirm the exact model and year before ordering — Boss Air Suspension kits are vehicle-specific, and correct fitment is what makes a load assist kit work properly.
FAQ
What's the best airbag kit for a tradie van in 2026?
For vans doing frequent loaded and unloaded runs, a Toyota HiAce load assist kit is the strongest general pick in 2026. Larger cargo vans carrying heavy tools most days suit a Ford Transit load assist kit instead.
Do airbag kits increase how much a van can legally carry?
No. A load assist airbag kit helps the existing suspension manage weight more evenly, but it doesn't change the vehicle's legal GVM or payload rating. Any change to those ratings needs an approved GVM upgrade.
Is a load assist kit necessary if I don't tow?
Yes, if the van or ute regularly carries tools, stock or equipment. Load assist kits address rear-end sag from carrying weight, which happens with or without towing.
How much air pressure should I run in a tradie van airbag kit?
Pressure should be adjusted to suit the load on each trip, running lower when empty and higher when fully loaded. The correct range depends on the specific kit and vehicle, so check the application guide or contact Boss Air Suspension for guidance.
Can I install a load assist kit myself?
Most Boss Air Suspension load assist kits use bolt-on brackets that don't require drilling on typical applications, which makes DIY installation realistic for someone comfortable working under a vehicle. A workshop install is a safer option if you're unsure.
Do airbag kits work with leaf spring or coil spring vans and utes?
Yes. Load assist airbag kits are designed to work alongside the vehicle's existing leaf spring or coil suspension rather than replace it.
How long does a load assist airbag kit last?
Boss Air Suspension load assist kits are backed by a five-year warranty, reflecting how they're built for long-term daily use in Australian conditions.
Is a load assist kit different from full air suspension?
Yes. A load assist kit adds airbags to the existing suspension to help manage load, while a full air suspension or air strut kit replaces more of the suspension system itself.
One last thing
Check ride height with the van or ute empty before assuming a load assist kit is needed — if the rear end already sits noticeably low with no load on board, the issue may be worn springs rather than a payload problem, and that's worth ruling out first.
