The beauty of airbag suspension is the ability to adjust pressure to match your exact load. Start with 20-30 PSI for light loads and everyday driving, increasing to 40-60 PSI when carrying camping gear or roof-top tents. For heavy towing applications such as caravans or boat trailers, increase pressure to 70-100 PSI to maintain level ride height and optimal handling. Always adjust pressure when load changes — running excessive pressure when empty will create a harsh ride, while insufficient pressure when loaded defeats the purpose of the system.
This kit is designed for installation by experienced DIYers or professional workshops, with an estimated fitment time of approximately 120 minutes (2 hours). Minor drilling is required to mount the airbag brackets securely to the chassis. All necessary hardware, fittings, and detailed instructions with diagrams are included. The QR code on the packaging provides instant access to Airbag Man's comprehensive online installation guides and videos. While wheel alignment is not typically required for airbag installation (unlike lift kits), it's recommended to check alignment if you notice any handling changes after fitment. Consider pairing with upgraded shock absorbers for maximum load-carrying performance.

This Airbag Man CR5123 kit is specifically engineered for the Holden Colorado 7 Wagon RG series manufactured between 2013 and 2016 with factory rear coil spring suspension. It will not fit Colorado 7 models outside this year range or vehicles with modified suspension. The kit is designed to work in conjunction with your existing coil springs, not as a replacement. If you're unsure about your exact model year or suspension configuration, our team can verify fitment using your VIN number — simply contact us with your vehicle details for confirmation.
While airbag helper kits don't technically increase your vehicle's legal payload rating (which is set by the manufacturer), they allow you to safely carry loads up to your vehicle's maximum GVM by preventing rear suspension collapse and maintaining proper ride height. The airbags support the load in conjunction with your factory springs, preventing squat and maintaining optimal suspension geometry. Most Colorado 7 owners find they can comfortably tow caravans up to 2500kg or carry 300-400kg of camping gear without rear sag when properly inflated. Always operate within your vehicle's published GVM and towing capacity limits regardless of suspension modifications.
The CR5123 kit is a complete installation package including two heavy-duty airbags designed for coil spring applications, all mounting hardware and brackets, nylon air lines of sufficient length for routing, brass fittings and connectors, an inflation valve assembly, and comprehensive installation instructions accessible via QR code. Everything you need for installation is in the box except basic hand tools. The kit uses manual inflation via the included valve — you can inflate at any service station or with a portable compressor. Optional upgrades like onboard air compressor systems with in-cab controls are available separately for added convenience.
Absolutely — this is one of the primary applications for airbag suspension systems on the Colorado 7 Wagon. When towing a caravan or trailer, the tongue weight often causes significant rear squat, which negatively affects steering, braking, headlight aim, and overall stability. The Airbag Man kit allows you to dial in the exact air pressure needed to level your vehicle regardless of tongue weight, dramatically improving towing safety and comfort. Many Colorado 7 owners report transformative improvements in caravan towing stability, reduced trailer sway, and better control on corrugated roads. The adjustability means you can run lower pressure when the van is unhitched, maintaining comfortable ride quality for daily driving.
No, this airbag helper kit works with your factory suspension components without requiring additional upgrades. The airbags install between the chassis and rear axle, working in harmony with your existing coil springs, shock absorbers, and control arms. However, if you're carrying consistently heavy loads or doing serious outback touring, many Colorado 7 owners choose to upgrade their shock absorbers at the same time for improved damping performance under load. Worn shocks will compromise the benefits of the airbag system. If your vehicle has done significant kilometres or you notice deteriorated ride quality, consider replacing shocks during airbag installation for maximum benefit.
Wheel alignment is generally not required after airbag installation because you're not altering suspension geometry or ride height in the same way as lift kits. The airbags simply provide additional support to prevent compression under load. However, if your Colorado 7 hasn't had an alignment check recently, or if you notice any handling changes or uneven tyre wear after installation, an alignment check is recommended. Any time you work on suspension components, it's good practice to verify alignment. Unlike lift kits which mandate immediate alignment due to changed suspension angles, airbag systems maintain factory geometry when properly installed.
One of the key advantages of this system is the ease of adjustment — no special equipment required. The kit includes an inflation valve (similar to a tyre valve) that can be inflated at any service station using their air compressor, or with any portable 12V compressor or hand pump. Deflation is equally simple via the valve release. Adjust pressure based on your load: run 20-30 PSI for light loads, 40-60 PSI for moderate camping gear, and 70-100 PSI for heavy towing. The entire adjustment process takes just minutes. Many users opt to add an aftermarket onboard compressor system with in-cab controls for ultimate convenience, allowing adjustment without getting under the vehicle.
No, airbag suspension helper kits are not designed to increase ride height or provide tyre clearance like a lift kit does. The airbags work with your factory springs to prevent compression under load, maintaining standard ride height rather than raising it. If your goal is to fit larger tyres for improved off-road capability or aesthetics, you'll need a proper suspension lift kit that includes raised springs, extended shocks, and potentially modified control arms. Airbag systems are specifically for load support, leveling, and improving handling under weight — they're complementary to lift kits but serve a completely different purpose in suspension modification.
Airbag Man stands behind their products with comprehensive warranty coverage, reflecting their confidence in product quality and durability. Specific warranty terms vary by component, but typically include multi-year coverage on airbags and hardware against manufacturing defects. Warranty details are included with your kit documentation. To maintain warranty validity, ensure proper installation following Airbag Man's instructions, operate within your vehicle's load ratings, and perform regular visual inspections for wear or damage. Airbag Man's 25+ year reputation in the Australian market is built on product reliability and standing behind their warranties. Contact us for specific warranty terms or to register your product after installation.
One of the major advantages of airbag systems over permanent suspension modifications like helper springs or coil spacers is the ability to deflate when running empty. When you're not carrying loads or towing, simply reduce air pressure to 5-15 PSI (or even deflate completely for some applications), and your Colorado 7 will maintain its factory ride comfort characteristics. This adjustability means you get the best of both worlds: strong load support when needed, and comfortable daily driving when unloaded. This makes airbag systems particularly popular with touring families and tradies who experience dramatic load variations between work and weekend use.
