The Airbag Man Helper Kit suits the Holden Colorado RG (2012 onwards) on factory and 2" lifted leaf spring suspension, adding genuine Firestone air springs rated for constant load support without replacing your leaf springs. Adjustable air pressure lets you eliminate rear sag under a canopy, caravan or trailer load and hold factory ride height on demand. It pairs cleanly with our leaf spring range for heavier constant loads. Firestone airbags carry a lifetime warranty, and it's in stock in Australia with fitment support from our team.
Airbag Man helper kits use heavy-duty rubber bellows that mount between the chassis and the leaf pack – add air when the load goes on to bring the vehicle back level, then let it out and the standard springs carry on exactly as before. Because each side inflates independently, you can also correct for an off-centre load like a slide-on or water tank.
They shine when the load keeps changing – a van on the towball some weekends, a loaded tray on others. Worth being clear about what they don't do: helper airbags don't increase your GVM or payload; they manage ride height and stability within the vehicle's existing ratings. If the vehicle is always loaded, upgraded springs (with airbags for the variation on top) is the better setup.

This helper kit doesn't change your leaf spring rate — it adds adjustable air support on top of the factory or existing leaf springs already fitted to your Colorado RG. Increase air pressure to counter constant loads such as canopies, tow bars, water tanks and long-range fuel tanks, or run low pressure for unladen comfort. If you're carrying a heavier constant load year-round, ask our team about pairing this kit with a higher-rated leaf from our suspension components range.
Fitting is a bolt-on job most experienced DIY installers can finish in a few hours with basic hand tools, though professional fitment is recommended if you're not confident working under the vehicle. Wheel alignment isn't required for this kit on its own, since it doesn't permanently alter ride height, but check alignment if it's part of a wider suspension upgrade. Run the airbags in for the first 500km at a lower pressure setting to seat the rubber sleeve and mounting brackets before loading fully. If your Colorado RG is running a 2" lift, pair this helper kit with correctly matched control arms up front for consistent handling.
Airbag Man builds its air suspension range in Australia specifically for local 4WDs and utes, using Firestone air springs as the core component of every kit. Every helper kit carries a lifetime warranty on the Firestone airbag itself, giving tradespeople and tourers long-term confidence in a component that's under constant load.

This kit suits Colorado RG owners who tow caravans, boats or trailers and want to stop the rear end sagging under hitch weight. It's equally suited to tradespeople running heavy canopies, tool boxes or generators who need to keep the tray level and headlights aimed correctly. For anyone regularly switching between empty and loaded running, adjustable airbag suspension gives more flexibility than a fixed leaf spring change alone.
This Airbag Man Helper Kit is in stock in Australia and dispatches fast from local stock, with our team on hand to confirm fitment for your specific Colorado RG configuration. Check exact fitment using our parts finder for the Colorado RG, or get in touch before you order if you're unsure what your ute needs.

Genuine Airbag Man suspension from an authorised Australian dealer.
Yes, this Airbag Man Helper Kit is built specifically for the Holden Colorado RG built from 2012 onwards, fitted with leaf spring rear suspension. It fits both standard-height vehicles and Colorado RGs running up to a 2" lift, since the airbags mount alongside the existing leaf spring rather than replacing it. If you're running a different rear suspension setup or an earlier RC-series Colorado, contact our team to confirm compatibility before ordering.
This helper kit doesn't add a permanent lift — it's designed to eliminate rear sag and restore factory ride height when your Colorado RG is loaded with a canopy, tow ball weight or tray cargo. Air pressure is adjustable, so you inflate the Firestone air springs to support the load and can deflate for a softer unladen ride. If you're after a genuine lift in inches, pair this kit with a dedicated leaf spring upgrade from our leaf springs range.
The kit includes 2 x Firestone air springs, upper and lower mounting brackets, chrome-plated recessed inflation valves, a nylon air line kit with fittings, and all mounting hardware. Fitting instructions are included, and inflation is done manually through the valve. An onboard compressor or in-cab gauge isn't included but can be added separately for convenience.
Yes, this is one of the most common uses for the kit. Adjustable air pressure lets you counter tow ball download and trailer weight, keeping the rear of the Colorado RG level and stable instead of sagging under hitch load. Maintaining factory ride height under tow also keeps headlights correctly aimed and steering geometry closer to normal.
Not for this helper kit specifically, since it doesn't change ride height or front suspension geometry. If your Colorado RG already runs a 2" front lift as part of a wider suspension package, upgraded control arms are worth considering for correct front-end geometry, but that's a separate consideration to this rear airbag helper kit.
Wheel alignment isn't mandatory for this kit alone, because it doesn't permanently alter your vehicle's ride height or suspension geometry. If you're fitting this helper kit alongside a lift kit or other suspension changes, get an alignment done as part of that broader install. Our team can advise what's needed based on your full setup.
This is an air-adjustable helper kit rather than a fixed spring rate product, so you tune support by adjusting air pressure rather than selecting a different spring. If you need a permanently higher constant load rating, we can discuss pairing this kit with a heavier-rated leaf from our suspension components range.
Because this kit doesn't add permanent lift, it won't change your tyre clearance on its own. Tyre fitment depends on your existing ride height, wheel offset and any separate lift kit fitted to the Colorado RG. If you're planning larger tyres, talk to our team about combining this helper kit with a suspension lift for the extra clearance.
The Firestone air springs in this kit carry a lifetime warranty from Firestone, covering the airbag itself against manufacturing defects. Mounting brackets and hardware are covered under standard supplier warranty terms. Keep your proof of purchase from 4WD Suspension and contact our team if you have any warranty questions.
Yes, the kit is designed to run at low or no air pressure for a normal unladen ride, then be pumped up only when you're carrying a load or towing. This means daily driving comfort isn't compromised when the vehicle is empty. Many Colorado RG owners run it permanently fitted and simply adjust pressure to suit whatever they're carrying that day.
