Airbag pressure should be adjusted based on your current load configuration. Start at 5-10 PSI when empty to maintain ride comfort, then increase pressure incrementally as you add cargo, passengers, or towing equipment. Most Colorado RG owners run 20-40 PSI for typical towing scenarios, while heavy GVM loads may require 60-80 PSI. Always inflate both airbags equally unless compensating for specific off-centre load distribution. Common rear accessories that affect pressure requirements include slide-on campers, steel tray conversions, dual spare wheel carriers, long-range fuel tanks, and drawer systems.
This Airbag Man kit is designed for straightforward installation and can be fitted by experienced DIYers with basic hand tools in approximately 120 minutes. Professional installation is recommended for those unfamiliar with suspension work. The kit includes comprehensive instructions accessible via QR code, with step-by-step photography and torque specifications. No cutting or permanent modifications are required - all components bolt directly to existing chassis mounting points above the rear axle. After installation, a 500km settling period is recommended before final pressure adjustment. For Colorado RG owners who have installed lift kits, select the RR4717 variant to ensure proper airbag positioning and suspension travel clearance.

This kit fits all Holden Colorado RG models from June 2012 to 2020 in both 4x2 and 4x4 configurations. The RR4707 variant suits standard height suspension, while RR4717 is specifically designed for vehicles with existing 2-inch lift kits. Z71 and HSV SportsCat models are compatible but will experience a slight rear height increase. This kit does NOT fit HSV SportsCat+ or SportsCat SV models, nor can it be installed on vehicles with rear de-coupling anti-roll bars or SupaShock suspension systems.
Airbag Man helper kits are designed to support loads up to your Colorado RG's maximum GVM rating when properly inflated. The Firestone airbags provide progressive load support from 5 PSI (minimal assistance) up to 100 PSI (maximum support), allowing you to adjust capacity based on current load. Most Colorado owners find 20-40 PSI adequate for towing caravans up to 3000kg, while heavy tray loads or slide-on campers may require 60-80 PSI. The airbags work in conjunction with your existing leaf springs, not as a replacement, sharing the load to prevent spring sag and maintain optimal suspension geometry.
This Airbag Man kit includes everything needed for installation: two genuine Firestone double-convoluted airbags with lifetime warranty, all mounting brackets and hardware, nylon air line tubing, inflation fittings, external inflation valves, and comprehensive installation instructions with QR code access. The kit is designed as a complete bolt-on solution requiring no additional fabrication or parts sourcing. Note that in-cab compressor systems and wireless inflation controls are sold separately as optional accessories, though many Colorado owners prefer the simplicity of manual inflation using a portable compressor or service station air.
Yes, this airbag helper kit dramatically improves towing stability and safety on your Colorado RG by eliminating rear squat and maintaining factory suspension geometry under load. When towing caravans, boat trailers, or horse floats, the adjustable airbags prevent the rear end from sagging, which improves headlight aim, reduces steering vagueness, enhances braking performance, and minimizes body roll during cornering. The adjustable nature means you can fine-tune pressure for different trailer weights, and deflate when not towing to restore comfortable unladen ride quality. Thousands of Australian Colorado owners rely on Airbag Man systems for safer, more controlled towing experiences on both highways and corrugated outback tracks.
The Airbag Man helper kit works perfectly with factory Colorado RG suspension and requires no mandatory upgrades. However, if you're building a serious touring or heavy-duty work vehicle, consider pairing this kit with upgraded rear shock absorbers for improved damping control under load, and ensure your existing leaf springs are in good condition without excessive wear or fatigue. If you've already installed a lift kit, make sure to select the RR4717 variant designed for 2-inch lifted suspension. The airbags integrate seamlessly with factory or aftermarket suspension components and can be combined with other upgrades as your requirements evolve.
While professional installation is recommended, experienced DIY mechanics can install this kit at home using basic hand tools in approximately 120 minutes. The kit includes comprehensive step-by-step instructions with detailed photography and torque specifications, accessible via QR code on the packaging. Installation involves mounting the airbags between the chassis rail and axle using supplied brackets, routing air lines along the chassis to external inflation valves, and ensuring proper clearance throughout suspension travel. No cutting, welding, or permanent modifications are required. If you're uncomfortable working under your vehicle or lack appropriate jack stands and safety equipment, professional installation by a qualified 4WD workshop is strongly advised.
Correct air pressure depends entirely on your current load configuration. When empty or lightly loaded, run 5-10 PSI to maintain comfortable ride quality without excessive rear stiffness. For typical daily driving with average cargo, 15-25 PSI provides good support. When towing caravans or carrying heavy tray loads, increase pressure to 40-70 PSI until the rear suspension returns to factory ride height with minimal sag. Maximum pressure is 100 PSI for extreme loads approaching GVM limits. Always inflate both airbags equally unless deliberately compensating for off-center loads, and adjust pressure based on real-world performance rather than arbitrary numbers.
When properly adjusted, this airbag system has minimal impact on unladen ride quality. The key is running appropriate pressure for your current load - when empty, reduce pressure to 5-10 PSI so the airbags provide gentle support without over-stiffening the rear suspension. Many Colorado owners deflate completely when not carrying loads, allowing the factory leaf springs to provide standard ride characteristics. The beauty of adjustable air suspension is versatility: firm and controlled when loaded or towing, comfortable and compliant when empty. This eliminates the compromise of fitting heavy-duty springs that ride harshly unladen or soft springs that sag excessively under load.
This kit features genuine Firestone airbags covered by a lifetime manufacturer's warranty against defects in materials and workmanship, providing exceptional long-term value and peace of mind. The comprehensive warranty coverage reflects Firestone's confidence in their airbag construction quality and durability under Australian conditions. Additional kit components including brackets, fittings, and air lines are covered by Airbag Man's standard warranty terms. To maintain warranty validity, ensure correct installation following provided instructions, operate within specified pressure ranges, and inspect components regularly for damage or wear. Airbag Man's Australian support team provides expert technical assistance throughout your ownership experience.
Absolutely - this Airbag Man kit is designed for both on-road and off-road use on your Colorado RG. The Firestone airbags are constructed from durable reinforced rubber capable of withstanding articulation, compression cycles, stone strikes, and harsh outback conditions. For serious off-road touring, simply adjust pressure to match terrain and load: reduce to 10-20 PSI on corrugated tracks for improved compliance and comfort, or maintain higher pressure when carrying heavy camping gear to prevent bottoming out. The airbags are positioned well above the axle and protected from direct strike damage, though regular visual inspections for abrasion or cuts are recommended after extreme off-road adventures. Thousands of Colorado tourers run Airbag Man systems throughout remote Australian regions with complete reliability.
Perfect for Our Loaded Family Camping Trips

Essential Upgrade for Heavy Touring Loads
