Airbag pressure should be adjusted based on your total rear axle load. For unladen or light loads (under 200kg), run 5-20 PSI to maintain factory ride quality. For medium loads such as camping gear, toolboxes, or light trailers (200-500kg), inflate to 30-50 PSI. For heavy towing with caravans, camper trailers, boat trailers, or maximum payload (500kg+), inflate to 60-100 PSI depending on load weight and desired ride height. Always adjust pressure with vehicle loaded to achieve level stance, and check regularly during long trips as temperature changes can affect airbag pressure.
This kit requires drilling and cutting for proper installation, and should be fitted by a qualified mechanic or experienced DIY installer with appropriate tools and safety equipment. Estimated installation time is approximately 120 minutes for both sides. The kit includes comprehensive step-by-step instructions accessible via QR code, with detailed diagrams showing mounting points and airline routing. Valve stems are typically mounted in rear bar, side panel, or tub location for easy access. After installation, inflate airbags to 20 PSI and test for leaks using soapy water solution before loading vehicle. When upgrading suspension, consider pairing airbags with premium shock absorbers for optimal load control and ride quality.

This Airbag Man CR5038 kit is specifically designed for Toyota 4Runner and Hilux Surf models from 1988 to 1997 that are equipped with factory coil spring rear suspension. It will not fit leaf spring rear variants or later model 4Runners with different suspension designs. The kit installs inside the existing coil springs and requires drilling and cutting for proper mounting. If you're unsure about your vehicle's rear suspension type or fitment compatibility, contact our team with your VIN or chassis details for confirmation before ordering.
When inflated to maximum pressure (100 PSI), this Airbag Man kit can provide up to 2000kg (2 tonnes) of additional load support across the rear axle. This doesn't increase your vehicle's legal GVM or payload rating, but rather prevents spring compression and maintains ride height when operating within your vehicle's rated capacity. The airbags work in conjunction with your factory coil springs to share the load, preventing bottoming out and maintaining proper suspension geometry. Always stay within your vehicle's manufacturer-specified payload and towing limits regardless of airbag support.
The complete kit includes two heavy-duty airbags designed to fit inside your coil springs, all necessary mounting brackets and hardware, nylon airline tubing and fittings, valve assembly for inflation/deflation, and detailed installation instructions with QR code access to digital guides. Everything needed for installation is provided except for an air source (compressor or manual pump). The kit does require drilling and cutting during installation, so appropriate tools are necessary. An optional onboard compressor system can be purchased separately for in-cabin pressure adjustment convenience.
Yes, this kit is specifically designed to improve towing performance and stability when hauling caravans, camper trailers, boat trailers, and other towable loads. The airbags eliminate rear-end sag caused by towball weight, maintaining level vehicle stance which improves headlight aim, braking balance, and steering control. By preventing spring compression, the kit also maintains proper suspension travel and reduces body roll during cornering. For optimal towing performance, inflate the airbags to achieve a level stance with your trailer connected — typically between 40-80 PSI depending on towball weight and payload.
No, this airbag helper kit works with your existing factory suspension components including coil springs, shock absorbers, and control arms. The airbags are designed to supplement your factory springs, not replace them, so no other modifications are required for basic installation. However, if you're also looking to increase ground clearance or improve off-road capability, you may want to consider a complete suspension upgrade including lifted coil springs and upgraded shocks. Many 4Runner owners combine airbag kits with quality shock absorbers for the ultimate load-carrying and touring setup.
A wheel alignment check is recommended after installing any suspension component, including airbag helpers. While the kit itself shouldn't significantly alter alignment settings when properly installed, the drilling and mounting process may slightly shift suspension geometry. More importantly, when you inflate the airbags and raise the rear of your vehicle, this changes the relationship between front and rear ride heights which can affect handling and tyre wear. A professional alignment ensures your vehicle tracks straight, tyres wear evenly, and handling remains predictable across all load conditions.
Yes, that's the primary advantage of this system — infinite adjustability to match your exact load requirements. Run 5-20 PSI when unladen for factory-like ride quality, increase to 30-50 PSI for moderate loads like camping gear, and inflate to 60-100 PSI for heavy towing or maximum payload. You can adjust pressure in seconds using any air source including garage compressor, service station air line, or portable pump. For ultimate convenience, consider adding an onboard compressor system for in-cabin adjustment on the go, allowing you to fine-tune ride height and comfort during trips.
This airbag kit is not a suspension lift kit and does not provide additional ground clearance or tyre clearance by itself. The airbags restore or maintain factory ride height when the vehicle is loaded, preventing sag rather than creating lift. If you want to fit larger tyres on your 4Runner/Surf, you'll need a proper suspension lift kit with raised coil springs and extended shock absorbers. However, the airbag kit works perfectly in conjunction with a lift kit — many owners install both for the combined benefits of increased clearance and adjustable load support.
This Airbag Man CR5038 kit is covered by the manufacturer's comprehensive warranty against defects in materials and workmanship. Airbag Man has been manufacturing air suspension products in Australia for over 25 years and stands behind their quality with full warranty support through authorised dealers. Warranty coverage requires professional installation or competent DIY fitting following the provided instructions, and doesn't cover damage from accidents, misuse, or operation beyond specified pressure limits. For specific warranty terms and conditions, refer to the documentation included with your kit or contact our team.
Absolutely — this Airbag Man system is engineered for daily driving, highway touring, and everything in between. When deflated or set to low pressure (5-20 PSI), the airbags have minimal effect on ride quality, allowing your factory suspension to function normally for comfortable unladen driving. When you need to carry loads or tow, simply inflate to the required pressure for stable, controlled performance. The system doesn't compromise on-road manners or handling — it enhances them by maintaining proper vehicle stance and suspension geometry regardless of load. Thousands of Australian tradies and tourers use Airbag Man systems for daily transport and weekend adventures.
Perfect for Our Family Camping Adventures
Got the Airbag Man kit fitted to our 4Runner before our last trip down the coast and what a difference it made. With the camper trailer, swags, and all the family gear loaded up, the rear end used to sag pretty badly but these air suspension helpers kept everything level and the ride smooth. Installation was straightforward enough, and the quality feels solid for the price point.(5)
Perfect for Hauling Tools and Equipment Daily
Been running this Airbag Man helper kit on my Surf for about 6 months now and it's been absolutely brilliant for when I'm loaded up with gear and materials heading to job sites. Makes a massive difference to how level the back sits when I've got a tonne of tools in there, and the ride quality is way better than the saggy rear end I had before. Installation was pretty straightforward too, took me a couple hours in the shed on a Saturday arvo.(5)
Perfect for Our Loaded Family Camping Trips
Finally sorted out the saggy rear end when we load up the 4Runner for weekend camping trips with the family. The Airbag Man helper kit made a massive difference to how level the car sits, and the ride is much smoother now even with the rooftop tent, fridge and all the gear loaded up. Installation was straightforward enough for a home job, and being able to adjust the pressure depending on the load is brilliant.(5)
