Best overall for dual cab utes in 2026: the Boss Extreme Series Double Bellow Load Assist Kit. Best for heavy commercial towing: the Boss Premium Heavy-Duty Airbag Suspension Kit. Best for DIY fitment: the Boss No-Drill Airbag Suspension Kit. This guide breaks down which load assist airbag kit suits your dual cab ute, based on how you tow, how much you carry and how you plan to install it.
- Boss Extreme Series Double Bellow kit is the best all-round load assist airbag kit for dual cab utes in 2026 - buy it if you tow or carry occasionally.
- Boss Premium Heavy-Duty kit suits utes doing regular heavy commercial towing where sag is a daily problem.
- Boss No-Drill kit is the pick for owners fitting their own suspension without drilling the chassis.
- Coil assist kits only suit coil-sprung applications - most dual cab utes run leaf springs at the rear, so check fitment first.
- None of these kits increase your ute's legal GVM or towing capacity unless fitted as part of an approved GVM upgrade.
Why this matters
A dual cab ute with a heavy tow ball load or a full tray sags at the back. Rear-end sag reduces steering feel, lifts your headlights and puts more weight on already-stressed leaf springs.
A load assist airbag kit works with your ute's existing rear suspension rather than replacing it. Air is added to the bags to support the load and bring the vehicle back closer to level, which improves stability while towing or carrying gear.
It's worth being clear on one point: a load assist kit does not increase your vehicle's legal payload, GVM or towing capacity. It helps the suspension carry the load you're already legally allowed to carry more comfortably and predictably. If you choose the right load assist airbag kit for your specific ute and use case, you get better ride height control and less bottoming out on rough roads - not a bigger legal limit.
What makes the best load assist airbag kit for a dual cab ute
- Vehicle-specific fitment - brackets and airbag shape matched to your exact model and rear suspension geometry, not a generic universal kit
- Adjustable air pressure - the ability to increase or decrease pressure depending on whether you're empty, loaded or towing
- Bellow design suited to load - double bellow airbags generally handle heavier and more constant loads better than single bellow designs
- Installation method - drilled bracket kits versus no-drill kits, depending on your comfort with the fitting job
- Warranty and local support - a kit backed by a five-year warranty and Australian-based technical advice if something needs checking
- Compatibility with your existing suspension - the kit must work alongside your leaf springs or coil springs, not against them

1. Boss Extreme Series Double Bellow Load Assist Kit: best load assist airbag kit for everyday dual cab towing
The Extreme Series Double Bellow kit is Boss Air Suspension's core load assist product for popular dual cab utes, including Ford Ranger, Toyota Hilux, Isuzu D-Max, Mitsubishi Triton, Nissan Navara and Mazda BT-50 applications. It bolts onto the existing rear suspension using vehicle-specific brackets, so it doesn't replace your leaf springs.
Air pressure is adjustable, which means you can run less air when the tray is empty and add air when you're loaded or towing. The kit ships with the airbags, brackets, air line and fittings needed for the install.
Boss Extreme Series pros:
- Vehicle-specific brackets for a proper fit, not a generic universal mount
- Double bellow design copes with a wider load range than single bellow airbags
- Backed by a five-year warranty
- Adjustable air pressure to suit changing loads
Boss Extreme Series cons:
- Doesn't increase your ute's legal GVM or towing capacity
- Air pressure needs to be checked and adjusted as the load changes
- Some models need brackets drilled into the chassis
Boss Extreme Series pricing: kits for Ford Ranger dual cabs range from $745 for the PHEV Nxt Gen (22+) kit to $830 for the Ford Ranger Super Duty (Dec 2025+) kit, with pricing varying by model and fitment.
Best for: dual cab ute owners who tow a van or trailer occasionally and want a reliable, vehicle-specific stability upgrade.
Verdict: Buy.
2. Boss Premium Heavy-Duty Airbag Suspension Kit: best load assist airbag kit for commercial towing
This kit is built for dual cab utes that carry or tow heavy loads on a regular basis - think tradies pulling a loaded tandem trailer every day or fleet vehicles that rarely run empty. Higher load-bearing bellows are designed to handle sustained weight rather than the occasional weekend load.
You can read more detail on the premium heavy-duty airbag suspension kit for commercial towing if your ute is doing daily heavy-duty work.
Premium Heavy-Duty pros:
- Designed for constant heavy loads, not just occasional towing
- Suits commercial and fleet use where the vehicle rarely runs light
- Backed by the same five-year warranty as the standard range
Premium Heavy-Duty cons:
- More capacity than most owner-drivers actually need
- Requires more attention to correct PSI when running lighter loads
Best for: commercial operators and tradies whose dual cab ute is loaded or towing most of the time.
Verdict: Buy for heavy daily use. Skip if you only tow a few times a year.
3. Boss No-Drill Airbag Suspension Kit: best load assist airbag kit for DIY installation
Some owners want the stability benefit without drilling into the chassis. The No-Drill kit uses a bracket design built to bolt to existing mounting points rather than requiring new holes.
Full install detail is covered in the guide to no-drill airbag suspension kits for easy DIY installation.
No-Drill Kit pros:
- No drilling required for the bracket install on eligible models
- Straightforward fit for owners comfortable working under their own vehicle
- Uses the same double bellow airbags as the standard range
No-Drill Kit cons:
- Not available for every dual cab ute model
- Bracket fitment still needs to match your exact vehicle
Best for: owners fitting their own load assist kit at home without chassis modification.
Verdict: Buy, once you've confirmed no-drill availability for your model.
4. Boss Coil Assist Kit: best for coil-sprung dual cab applications
Most dual cab utes run leaf springs at the rear, but some applications use coil-sprung suspension where a coil assist kit is the correct fit rather than an airbag kit. This product works alongside coil springs to support moderate extra load.
Coil Assist Kit pros:
- Purpose-built for coil-sprung suspension rather than leaf springs
- Suits moderate load increases without changing ride quality dramatically
Coil Assist Kit cons:
- Not compatible with leaf-spring rear ends, which rules it out for most dual cab utes
- Narrower range of applications than the airbag kits above
Best for: the smaller number of dual cab applications with coil-sprung rear suspension.
Verdict: Hold - confirm your ute's rear suspension type before considering this kit.
5. Load assist kit for GWM Cannon Alpha: best for GWM Cannon Alpha owners
The GWM Cannon Alpha has its own vehicle-specific load assist fitment, covered separately because bracket geometry and airbag placement differ from older dual cab platforms. Owners of this model should check the model-specific fitment guide rather than assume a universal fit.
GWM Cannon Alpha kit pros:
- Matched specifically to this newer platform's rear suspension geometry
- Same double bellow airbag design used across the Boss range
GWM Cannon Alpha kit cons:
- Model-specific, so it won't suit other utes
- Newer platform means fewer years of installer feedback compared with older models
Best for: GWM Cannon Alpha owners towing or carrying loads who need a correctly matched kit.
Verdict: Buy, for this specific model.
6. Air suspension for dual cab utes with canopies and campers: best for fitted-out trays
A canopy, tool boxes or a slide-on camper add constant static weight to the rear of a dual cab ute, even before you load anything inside. This changes the ride height and sag pattern compared with a bare tray, which is why it gets its own category here.
Canopy/camper setup pros:
- Accounts for the extra static weight of the fit-out itself, not just cargo
- Works with the ute's existing suspension rather than requiring a full suspension replacement
Canopy/camper setup cons:
- Needs an accurate weight figure for the fitted-out vehicle before choosing pressure settings
- Heavier permanent fit-outs may also need a hard-check of GVM compliance
Best for: dual cab utes permanently fitted with a canopy, tray fit-out or slide-on camper.
Verdict: Buy, after confirming your fitted weight.
How we ranked these kits
Each kit above is ranked against the six criteria listed earlier: fitment specificity, adjustable pressure, bellow design, install method, warranty and suspension compatibility. No single kit wins on every criterion - that's why the list is split by use case rather than a single leaderboard, so the ranking works as a decision guide rather than a popularity contest.
“If you're towing or loading most days, the Premium Heavy-Duty kit earns its keep. If it's occasional, the standard Extreme Series kit does the job.”
Which load assist airbag kit should you choose?
If you're unsure, start with the Boss Extreme Series Double Bellow Load Assist Kit - it covers the widest range of dual cab utes and use cases, from weekend towing to daily tool carrying. Step up to the Premium Heavy-Duty kit only if your ute is loaded or towing most days of the week.
Choose the No-Drill kit if you're fitting it yourself and want to avoid chassis modification, and check the Coil Assist Kit only if your rear suspension is coil-sprung rather than leaf-sprung. Model-specific buyers - GWM Cannon Alpha owners, or utes with a canopy or camper fitted - should go straight to the kit matched to that exact setup rather than the general-purpose option.
Whatever you land on for 2026, confirm the fitment against your exact model year before ordering, and set air pressure to suit the load you're actually carrying, not a guess.
FAQ
What's the best load assist airbag kit for a dual cab ute?
The Boss Extreme Series Double Bellow Load Assist Kit is the best all-round option for most dual cab utes in 2026, covering everyday towing and load carrying with vehicle-specific fitment. Heavier daily commercial use suits the Premium Heavy-Duty kit instead.
Do load assist airbag kits increase my ute's towing capacity?
No. A load assist kit supports the existing rear suspension and improves stability, but it does not increase your vehicle's legal payload, GVM or towing capacity. Any increase to those figures needs an approved GVM upgrade.
Is a coil assist kit the same as a load assist airbag kit?
No. Coil assist kits work with coil-sprung suspension, while load assist airbag kits work alongside leaf springs, which is what most dual cab utes run at the rear. Check your ute's rear suspension type before choosing between them.
Can I fit a load assist kit without drilling into my ute's chassis?
On eligible models, yes - the Boss No-Drill Airbag Suspension Kit uses brackets designed to bolt to existing mounting points. Not every dual cab model has a no-drill option available, so check fitment first.
How much does a load assist airbag kit cost for a dual cab ute?
Pricing varies by model. Ford Ranger dual cab kits from Boss Air Suspension range from $745 to $830 depending on the variant and model year, as of 2026.
Do I need a different kit if my ute has a canopy or slide-on camper fitted?
A canopy or camper adds constant static weight to the rear, which changes ride height and sag even before you load anything. Choosing a kit suited to a fitted-out tray, and weighing the vehicle accurately, gives a better result than treating it like a bare tray.
Is a load assist kit worth it for occasional towing?
Yes, if sag and reduced stability are noticeable when towing or loaded. The standard Extreme Series kit suits occasional use, while daily heavy towing points toward the Premium Heavy-Duty kit.
Does a load assist kit come with a warranty?
Boss Air Suspension load assist kits are backed by a five-year warranty, with Australian-based technical support if you need help with fitment or adjustment.
One last thing
The kit that fits your exact ute and rear suspension type always beats the kit with the most features on paper - a Premium Heavy-Duty kit set up wrong will ride worse than a correctly adjusted standard kit. Weigh your loaded ute once in 2026 before choosing pressure settings, and you'll get more out of any of the kits above.
