The beauty of airbag suspension is infinite adjustability — simply inflate to match your current load. For daily driving with minimal gear, run 10-20 PSI for comfortable ride quality. When loaded with camping equipment, roof racks, dual batteries, long-range fuel tanks, and fridges, increase to 50-80 PSI. For maximum loads including heavy towing (caravans, boat trailers, camper trailers), inflate to 100-150 PSI for optimal support and level stance. Always start with lower pressure and increase gradually while monitoring vehicle stance and ride quality.
Professional installation is recommended due to drilling requirements for bracket mounting, though experienced DIY mechanics with proper tools can complete the installation in approximately 180 minutes. The kit includes comprehensive step-by-step instructions accessible via QR code, with detailed diagrams showing exact mounting locations and torque specifications. Note that this is a helper spring system designed to work with your existing suspension — for comprehensive upgrades including increased ride height, consider pairing with upgraded shock absorbers and complete lift kits. Allow 500km break-in period for airbag seating and hardware settling, then recheck all mounting bolts for proper torque.

This is not a lift kit — it's a load-levelling and helper spring system designed to restore factory ride height when carrying heavy loads or towing. When your Landcruiser is empty, you run minimal air pressure (10-20 PSI) maintaining stock ride height and comfort. When loaded with gear or towing, you inflate the airbags (up to 150 PSI) to counteract sag and return the vehicle to level stance. For actual suspension lift and increased ground clearance, you'll need dedicated coil spring replacements or a complete lift kit, which can be paired with this airbag system for maximum versatility.
The complete kit includes everything needed for installation: two high-pressure airbags rated to 150 PSI, custom mounting brackets and all fastening hardware, nylon air line tubing, air line fittings and connectors, remote-mount inflation valves, and comprehensive installation instructions accessible via QR code. The instructions include detailed diagrams, torque specifications, and step-by-step guidance for proper fitment. Note that an air compressor for inflation is sold separately — you can use a portable 12V compressor, service station air, or install an onboard air system for convenience.
Absolutely — this high-pressure airbag system is ideal for towing applications where rear sag and stability are critical concerns. The 150 PSI capacity provides substantial load support to counteract the tongue weight of caravans, camper trailers, boat trailers, and heavy-duty work trailers. By maintaining level stance, the airbags improve weight distribution, reduce body roll, keep headlights properly aimed, and enhance braking performance. Many Landcruiser owners who regularly tow consider airbags essential equipment, as they allow you to dial in exact support for different trailer weights rather than being stuck with a fixed spring rate.
No, airbag helper springs don't require control arm upgrades as they work with your existing suspension geometry and don't alter ride height like a lift kit does. However, if your Landcruiser has high kilometres or you're planning comprehensive suspension improvements, upgrading to heavy-duty control arms can improve handling and durability. Control arm upgrades become more important if you're combining airbags with actual lift kits or running larger tyres. This airbag system is designed as a bolt-on helper spring solution that enhances your existing suspension rather than replacing it, so stock control arms remain perfectly adequate for most applications.
Wheel alignment is not mandatory after installing this airbag helper kit, as it doesn't alter suspension geometry or ride height like a lift kit does — it simply provides additional support within the existing suspension travel range. However, if you're installing airbags as part of broader suspension work, or if your vehicle hasn't had an alignment in some time, it's a good opportunity to check and correct alignment settings. Proper alignment ensures even tyre wear, optimal handling, and straight-line tracking. Many owners choose to get alignment checked as preventative maintenance whenever suspension work is performed, but the airbags themselves don't necessitate it.
Yes — infinite adjustability is the primary advantage of airbag suspension systems. You can run as little as 5-10 PSI when the vehicle is empty for comfortable daily driving, then increase to 50-80 PSI for moderate loads like camping gear and roof racks, and inflate up to 150 PSI maximum for heavy towing or maximum payload situations. This allows you to optimize ride quality and load support for every journey rather than being stuck with fixed spring rates. The remote inflation valves make pressure adjustment quick and convenient — simply use a tyre gauge and air compressor to dial in the exact support you need for current conditions.
This airbag kit doesn't provide suspension lift or additional clearance for larger tyres — it's designed to maintain factory ride height under load. If you want to fit larger tyres to your Landcruiser 76/78, you'll need an actual lift kit that raises the suspension and body. However, airbags pair excellently with lift kits, giving you both the increased clearance for bigger rubber and the load support to handle the extra weight of heavy touring tyres, wheels, and accessories. Many touring setups combine a 2-3 inch lift kit with airbags for the ultimate blend of clearance, load capacity, and adjustability for varying conditions.
Airbag Man products are backed by comprehensive manufacturer warranty covering defects in materials and workmanship — specific warranty duration and terms are detailed in the documentation included with your kit. Airbag Man has maintained an excellent reputation for over 25 years with proven durability in Australian conditions, and warranty claims are rare due to the robust construction quality. For warranty validation, retain your proof of purchase and follow the installation instructions carefully, ensuring all components are fitted correctly. 4WD Suspension Australia supports all warranty claims and can assist with any product issues should they arise.
Yes, absolutely — when running low pressure (10-20 PSI) with minimal or no load, the airbags provide comfortable daily driving characteristics very close to your stock suspension feel. Unlike solid helper springs or load-rated coil replacements that compromise empty ride quality, airbags only provide support when you need it through inflation. This makes them ideal for vehicles that serve dual duty as both daily drivers and weekend tourers or work trucks. You get comfortable, compliant ride quality for school runs and commuting, then simply inflate the airbags before loading up for camping trips, work hauling, or towing — the best of both worlds without compromise.
Perfect for Heavy Loads on Site
Been running this Airbag Man kit on my 78 Series for about six months now and it's been brilliant for carting tools and materials to job sites. The difference when loaded up is night and day - no more sagging rear end even with a full load of pavers or timber. Fitment was straightforward enough to do myself on a weekend, and the ride quality is so much better than the old setup when towing the work trailer.(5)
Perfect for Our Loaded Family Camping Trips
Fitted these airbag helper springs to our 78 Series before our last Cape York trip and the difference was night and day. With the camper trailer, roof tent, and all the kids' gear loaded up, the old girl sits level and handles beautifully instead of sagging at the rear. Installation was straightforward enough for a weekend in the shed, and the ride quality is so much better on corrugations when you can adjust the pressure to suit the load.(5)

Been running these airbag helpers on my 78 Series for about six months now and they've been brilliant for carting tools and materials around job sites. Makes a huge difference when the tray's loaded up - no more sagging and the ride stays level even with a pallet of bricks in the back. Fitted them up myself in the driveway over a weekend, instructions were pretty straightforward.(5)
Perfect Solution for Our Loaded Family Tourer
Been running these Airbag Man helper kits on our 78 Series for about six months now and they've completely transformed how the Cruiser handles when we're loaded up for camping trips. The difference in ride quality with the camper trailer hooked up and the back full of gear is night and day - no more sagging rear end or wallowing around corners. Installation was straightforward enough to tackle in the driveway over a weekend, and the adjustability means I can fine-tune the pressure depending on whether we're running solo or fully loaded with the family and all our camping gear.(5)
