The Airbag Man Helper Kit fits the Great Wall Cannon dual cab ute (2020-2022) and installs Firestone dual-convoluted air springs above the factory leaf springs to stop rear-end sag. Air pressure adjusts from 5 to 100 PSI, so you can run soft unladen and firm up in minutes once you've loaded a canopy, toolbox or caravan tow ball. It works with your existing leaf spring setup — no cutting, drilling or component replacement. Backed by Firestone's lifetime airbag warranty and dispatched from Australian stock.

Choose your operating pressure based on constant load rather than guesswork. Run 20-30 PSI for light loads such as tools or daily driving, 40-60 PSI for camping gear, roof racks or a moderate canopy, and 70-100 PSI for heavy loads such as full water tanks, a slide-on camper or a loaded caravan tow ball. Common rear-heavy accessories that call for airbag support include aluminium canopies, steel toolboxes and drawer systems, dual spare wheels, roof-top tents, long-range fuel or water tanks, and caravan or trailer tow ball weight.
Fitting is straightforward for an experienced DIY mechanic or a workshop, with an estimated fitting time around 2 hours using the existing chassis mounting points — no cutting or drilling of chassis rails is needed. Wheel alignment isn't typically required for an airbag-only install, but if you're also fitting lift kit components or upgraded control arms, get the alignment checked afterwards. After fitting, test the system at a few different pressures to find your settings for empty, moderate and full-load running, and check all air fittings with soapy water for leaks.
Airbag Man has specialised in Australian air suspension for over 25 years, pairing genuine Firestone commercial-grade airbags with brackets designed around local vehicles and load conditions. Every kit is backed by Firestone's lifetime warranty on the airbags themselves, and tradespeople, grey nomads and touring families rely on these kits for consistent load support. You can view the full Airbag Man range for other vehicle applications and combinations with lift kits.
This helper kit suits Cannon owners who regularly carry trade equipment, tow a caravan or box trailer, or run a loaded camper setup and want the rear end to sit level rather than sag. If your Cannon squats under a full tray or tow ball, this airbag suspension upgrade gives you adjustable support without replacing your leaf springs.
This Airbag Man helper kit is in stock now at 4WD Suspension Australia with fast dispatch nationwide. Our team can help confirm fitment and talk through combining it with other suspension upgrades — browse our full lift kit range or get in touch for advice specific to your Cannon.

Yes, SKU RR4736 is built specifically for the Great Wall Cannon dual cab ute produced from 2020 to 2022. It bolts to the factory leaf spring mounting points using laser-cut brackets, with no cutting or drilling required. If you're unsure about your exact build date or variant, our team can confirm fitment before you order.
This is a helper kit, not a lift kit, so it doesn't raise ride height on its own. Instead it uses adjustable air pressure between 5 and 100 PSI to counteract sag caused by load, bringing the rear back to a level position once the tray or tow ball is loaded. If you want a genuine ride height increase, pair it with a raised leaf spring upgrade or full lift kit.
The kit includes two Firestone dual-convoluted air springs, laser-cut mounting brackets, zinc-plated U-bolts and hardware, nylon air lines, inflation valves and fitting instructions accessible by QR code. An air compressor and pressure gauge aren't included, so you'll need one on hand to adjust and maintain pressure. Everything needed to mount the kit to factory locations is supplied.
Yes. Airbag pressure can be increased to counter tow ball download, which helps keep the Cannon level when towing a caravan, box trailer or boat. A level stance improves headlight aim, brake bias and general handling compared to running with the rear sagging under tow ball weight. Many owners run a lower pressure unladen and top up specifically before hitching up.
No, control arm upgrades aren't required for this kit. This is a rear leaf spring airbag system, while control arms relate to front independent suspension geometry. If you're also working on the front end, our control arm range is worth a look, but it's a separate consideration from this fitment.
A wheel alignment isn't typically required for an airbag-only install, since the kit works within the factory leaf spring's normal travel and doesn't alter suspension geometry at rest. If you're combining this kit with a lift kit or other suspension changes, we recommend having the alignment checked afterwards.
Rather than fixed spring rate options, this kit gives you a continuously adjustable range from 5 to 100 PSI, so you set your own effective support level for each trip. Light loads run well at 20-30 PSI, moderate loads at 40-60 PSI, and heavy loads such as a loaded caravan tow ball or slide-on camper at 70-100 PSI.
No change to tyre clearance should be expected, because this helper kit doesn't raise ride height — it only supports the existing leaf springs under load. If fitting larger tyres is the goal, you'll need a lift kit or raised leaf springs alongside this airbag kit.
The Firestone air springs are covered by a lifetime manufacturer warranty against manufacturing defects. Mounting brackets and hardware are covered under standard warranty terms through 4WD Suspension Australia. Keep your proof of purchase and contact our team if you ever need to make a claim.
Yes. Run a lower pressure around 20-30 PSI for comfortable unladen daily driving, then increase pressure only when you're carrying a heavier load or towing. Because it works with your factory leaf springs rather than replacing them, everyday ride quality stays close to standard when the airbags are run soft.
