The Airbag Man Helper Kit for Leaf Springs transforms your Holden Colorado RC 2008-2012 into a safer, more capable load carrier with adjustable air suspension technology that eliminates spring sag and improves steering, braking and ride comfort. Designed specifically for Colorado RC leaf spring applications, this complete airbag suspension kit delivers precise leveling control whether you're towing caravans, hauling trade gear, or touring the outback. Backed by Firestone's lifetime manufacturer warranty and Australian stock for fast dispatch nationwide.
An airbag helper kit is an air suspension system designed to work alongside your vehicle's existing leaf spring suspension. Unlike full replacement suspension systems, helper kits install between the chassis and axle to provide supplementary support when carrying heavy loads or towing. By inflating or deflating the airbags using an air compressor, you can adjust your vehicle's ride height and load-carrying capacity on demand. This makes them ideal for vehicles that experience variable loads—from empty daily driving to fully loaded weekend touring or trade work. The Airbag Man system uses premium Firestone airbags engineered specifically for Australian conditions, providing a cost-effective alternative to upgrading to heavy-duty leaf springs while maintaining factory ride quality when unloaded.
The Holden Colorado RC (2008-2012) is a workhorse ute popular with tradespeople, tourers and families alike. However, the factory leaf spring suspension can struggle when loaded with heavy toolboxes, canopies, roof racks, or when towing caravans and boat trailers. This leads to rear-end sag, reduced steering control, premature tire wear, and dangerous headlight angles that blind oncoming traffic. The Airbag Man Helper Kit solves these issues by providing up to 1000kg of additional load support, restoring your Colorado to level ride height regardless of payload. Whether you're hauling building materials across town or towing a camper trailer to Cape York, adjustable air pressure gives you precise control over your vehicle's stance and handling. This kit is particularly valuable for Colorado owners who experience variable loads—the ability to deflate the airbags when empty ensures you maintain factory ride comfort for daily driving, then inflate them instantly when it's time to work or tour.

The beauty of air suspension is its adjustability—you don't need to choose a fixed spring rate like traditional coil or leaf spring upgrades. Simply adjust air pressure to match your current load, from 5 PSI for empty daily driving up to 100 PSI for maximum load support. Common accessories that increase rear axle weight on the Colorado RC include aluminium or steel canopies (60-120kg), drawer systems (40-80kg), dual battery setups (30kg), long-range fuel tanks (80kg full), roof racks with roof-top tents (60-100kg), bullbars and rear bars (combined 80-120kg), and winches (35-50kg). When towing, the airbag system counteracts towball downforce from caravans (typically 200-300kg) and boat trailers (100-200kg). The Airbag Man kit provides the flexibility to accommodate any combination of these accessories without the harsh ride penalty of heavy-duty springs.
The Airbag Man Helper Kit RR4599 is designed for straightforward installation by experienced DIY enthusiasts or professional workshops. Expect approximately 120 minutes fitting time with basic hand tools—no welding or specialized equipment required. The kit includes all necessary mounting hardware, airbags, nylon air lines, and fittings for a complete bolt-on installation. While the airbag system doesn't affect wheel alignment the same way lift kits do, it's still recommended to check alignment after installation and whenever you make major changes to vehicle load. For optimal performance, allow a 500km break-in period where you vary the air pressure and loads to properly seat all components. If you're installing this kit alongside other suspension modifications such as upgraded control arms or heavy-duty shocks, coordinate the installation to ensure all components work together harmoniously.

Yes, the Airbag Man Helper Kit RR4599 is specifically engineered to fit all Holden Colorado RC models from 2008 to 2012, including both 4x2 and 4x4 variants. This kit is also compatible with Holden Rodeo KB and TF series from 1981-2002 that use rear leaf spring suspension. The kit works with factory standard suspension as well as vehicles with aftermarket lift kits or lowered suspension. If you've made significant modifications to your Colorado's rear suspension or axle, we recommend contacting our team to confirm fitment before ordering.
The Airbag Man Helper Kit can support up to 1000kg of additional load when inflated to maximum pressure (100 PSI). This doesn't increase your vehicle's legal GVM rating, but it helps your suspension manage loads more effectively within the manufacturer's specified limits. The adjustable nature means you can fine-tune support from 5 PSI for light loads up to 100 PSI for maximum towing and payload situations. This makes it ideal for varying loads like empty daily driving, fully loaded weekend camping trips, or towing caravans up to 3500kg. The system effectively counteracts rear-end sag caused by heavy canopies, toolboxes, dual batteries, long-range tanks, roof racks, and towball weight.
This is a complete installation kit that includes 2 x Firestone airbags with lifetime warranty, all mounting brackets and hardware for chassis and axle attachment, high-pressure rated nylon air lines, quick-connect fittings and connectors, inflation valves for easy pressure adjustment, U-bolts and fasteners, plus detailed printed instructions with QR code access to online fitting guides. Everything you need for installation is included except an air source—you can use a standard tire pump, portable air compressor, or connect to an onboard air system if your Colorado is already equipped. Optional wireless inflation systems and in-cab controllers are available separately for added convenience.
Absolutely—this is one of the primary applications for the Airbag Man Helper Kit. When towing caravans, camper trailers, or boat trailers, the towball weight (typically 200-350kg) causes the rear of your Colorado to sag, which negatively affects steering, braking, headlight aim, and overall stability. By inflating the airbags to match your specific towball weight, you restore the vehicle to a level stance, dramatically improving towing safety and handling. The adjustable system means you can set the perfect pressure for your particular trailer setup, then deflate the bags when not towing to maintain comfortable daily driving. Many experienced tourers consider airbag suspension essential safety equipment for serious caravan towing.
The Airbag Man Helper Kit works with your existing suspension components and doesn't require control arm upgrades for installation or basic operation. However, if you're planning to combine this kit with a suspension lift or if your Colorado already has a lift kit installed, upgraded control arms may be beneficial to correct suspension geometry and prevent premature wear on ball joints and bushings. Similarly, if your factory shock absorbers are worn or you're running heavy constant loads, pairing the airbag kit with heavy-duty shocks will provide better overall performance. Our suspension specialists can recommend the best combination of components for your specific use case and budget.
While airbag helper kits don't alter suspension geometry the way lift kits do, it's still good practice to have your wheel alignment checked after installation, especially if you'll be running the airbags at higher pressures regularly. When the airbags are inflated, they can slightly change the rear axle position, which may affect the relationship between front and rear tracking. A post-installation alignment check ensures your Colorado tracks straight, maximizes tire life, and maintains optimal handling characteristics. Most professional installers will recommend an alignment as part of the installation service, particularly if you're combining the airbag kit with other suspension modifications or if your alignment was already borderline before installation.
One of the major advantages of air suspension is that you don't need to choose a fixed spring rate like traditional coil or leaf spring upgrades—the airbags provide infinitely adjustable spring rates simply by changing air pressure. You can easily adjust pressure yourself using any air source from a simple hand pump to a portable compressor or onboard air system. For daily unloaded driving, run 5-10 PSI for factory-like ride comfort. Add 20-40 PSI for moderate loads like camping gear. Increase to 60-80 PSI for heavy canopies and roof racks. Use 80-100 PSI for maximum towing support. The inflation valves are typically mounted in accessible locations near the rear bumper or inside the rear wheel arch for convenient adjustment without tools.
The Airbag Man Helper Kit primarily affects load support and ride height under load conditions—it's not designed as a lift kit for tire clearance purposes. When inflated to maximum pressure, the kit can raise the rear of your Colorado by approximately 50mm, which may provide minimal additional clearance for slightly larger tires. However, if your primary goal is fitting larger off-road tires, you should consider a proper suspension lift kit that raises both front and rear while maintaining correct suspension geometry. The airbag kit can be installed in conjunction with a lift kit to provide the benefits of both increased ground clearance and adjustable load support. Many Colorado owners run a 2-3 inch lift kit with airbags for the ultimate touring and towing setup.
The Airbag Man Helper Kit RR4599 features genuine Firestone airbags that come with a lifetime manufacturer's warranty—one of the best warranty coverages in the air suspension industry. This lifetime warranty covers manufacturing defects in the airbags themselves, providing long-term peace of mind for your investment. The mounting hardware, brackets, air lines, and fittings carry a standard manufacturer's warranty against defects. Warranty coverage requires proper installation according to the supplied instructions and normal use within the product's specifications. Keep your proof of purchase and register your product with Airbag Man for full warranty protection. This comprehensive warranty coverage reflects Airbag Man's confidence in their products and commitment to customer satisfaction.
The Airbag Man Helper Kit is absolutely suitable for daily driving—in fact, its adjustability makes it ideal for vehicles that experience variable load conditions between daily commuting and weekend work or recreation. When your Colorado is unloaded for normal daily driving, simply deflate the airbags to 5-10 PSI and the vehicle will ride almost exactly like factory specification with no harsh or stiff feel. When it's time to load up for work or touring, inflate to the appropriate pressure for your load. This adjustability is a major advantage over fixed heavy-duty spring upgrades that ride harshly when empty. Many tradespeople and families appreciate having one vehicle that drives comfortably empty during the week but can handle serious loads on weekends without any compromise.
Perfect for Our Loaded Family Adventures
These airbag helpers have completely transformed our Colorado when we head out camping with the kids. Used to get serious sag with the roof tent, fridge, and all the gear loaded up, but now the rear end sits level and the ride is actually better than empty. Installation was straightforward enough for a weekend in the garage, and the difference when towing our camper trailer is night and day. Absolutely worth every cent for anyone doing regular touring.(5)
