The beauty of airbag suspension is infinite adjustability — you simply inflate to the pressure required to level your vehicle under load. Start at 5-10 PSI for unladen driving to maintain factory ride comfort. Gradually increase pressure in 5-10 PSI increments as you add payload weight, towing equipment, roof racks, bull bars, rear bars, long-range fuel tanks, water tanks, drawer systems, or caravan tow ball weight. Maximum pressure of 100 PSI provides extreme load support for the heaviest touring or commercial applications. Always adjust both airbags equally and never exceed the manufacturer's maximum pressure rating.
This Airbag Man helper kit is designed as an "Easy Fit" system with an approximate installation time of 120 minutes for experienced DIY enthusiasts or professional workshops. Installation involves mounting the airbags between the chassis rail and leaf spring axle using the supplied brackets and hardware — no welding or permanent modifications are required. The nylon air lines are routed to a convenient location (typically near the rear bumper or inside the tray) where the inflation valves are mounted for easy access. While wheel alignment is not strictly required for airbag-only installations, we recommend a full suspension inspection and alignment check if you're also upgrading your suspension components or have noticed uneven tyre wear. Allow a brief settling period after installation and check all fittings for leaks before heading off-road or towing.

This air suspension helper kit is ideal for Toyota Landcruiser 70 Series owners who regularly carry heavy loads, tow caravans or trailers, or need the flexibility to adjust suspension performance on demand. Grey nomads touring Australia with slide-on campers, tradespeople carrying tools and equipment, mining and agricultural operators, and weekend adventurers towing off-road camper trailers will all benefit from the load-leveling capability and enhanced stability this system provides. If you're experiencing rear-end sag, poor headlight aim when loaded, or compromised handling when towing, upgrading to adjustable air suspension is one of the most effective and reversible modifications you can make.

Yes, this RR4700 kit is specifically engineered to fit Toyota Landcruiser 75 Series (1990-1999), 76 Series Wagon (1998-2024), 78 Series Troop Carrier (1998-2024), and 79 Series Single and Double Cab Utes (1999-2024). The kit is designed to work with factory leaf spring rear suspension on all these variants. If you have aftermarket leaf springs, heavy-duty springs, or a modified rear axle setup, please contact us to confirm compatibility before ordering.
This is an air suspension helper kit, not a lift kit — it's designed to restore and maintain factory ride height when carrying loads, not to increase ground clearance. When your Landcruiser is unladen, you'll run minimal air pressure (5-10 PSI) and maintain factory ride height. As you add payload weight or tow a caravan, you increase air pressure to bring the rear end back to level, eliminating sag. If you're looking for actual suspension lift, browse our range of 4WD lift kits which can be installed in combination with this airbag system.
The RR4700 kit includes everything needed for installation: two heavy-duty airbags, mounting brackets and hardware, nylon air line tubing, air fittings and connectors, inflation valve assemblies, and detailed installation instructions with QR code access to online guides. All fasteners, bushings and components required to bolt the system to your Landcruiser are included. The kit does NOT include an onboard air compressor or in-cab inflation system — these accessories are available separately if you want the convenience of adjusting air pressure from inside the vehicle while driving.
Absolutely — this is one of the most popular upgrades for Landcruiser owners who tow caravans, camper trailers, horse floats or boat trailers. The airbags eliminate rear-end sag caused by tow ball weight, maintain proper ride height for optimal headlight aim and braking performance, and significantly reduce body roll and sway during cornering and crosswinds. You'll experience much greater stability and control when towing, especially on long highway trips. For a complete towing setup, consider pairing these airbags with upgraded shock absorbers and heavy-duty leaf springs.
No, control arm upgrades are not required when installing airbag suspension helpers, as this kit works with your existing leaf spring suspension and does not alter suspension geometry or increase ride height. Control arms are typically upgraded when fitting suspension lift kits that raise the vehicle's centre of gravity and change control arm angles. However, if your Landcruiser already has worn control arm bushings or you're planning a comprehensive suspension rebuild, it's worth inspecting and potentially upgrading these components at the same time for optimal handling and durability.
Wheel alignment is not strictly required after installing airbag helpers, as the kit does not alter suspension geometry or steering components when properly installed. However, if you notice uneven tyre wear, steering pull, or if you're also replacing other suspension components during the same service, a wheel alignment is recommended. A full suspension inspection and geometry check is always good practice after any major suspension work. Most professional installers will offer an alignment check as part of the installation service to ensure your Landcruiser tracks straight and tyres wear evenly.
With the standard RR4700 kit, inflation valves are mounted in an accessible location (typically near the rear bumper or inside the tray), requiring you to stop the vehicle and manually adjust air pressure using a compressor or air line. If you want the convenience of adjusting air pressure on-the-go from inside the cab, Airbag Man offers optional in-cab inflation systems and onboard compressor kits that can be added to this setup. These accessories allow you to fine-tune suspension settings while driving to adapt to changing load conditions or road surfaces — particularly useful for serious tourers and frequent towers.
This airbag suspension helper kit does not provide suspension lift or increase clearance for larger tyres — it's designed to maintain factory ride height under load. If you're currently running factory tyre sizes and experiencing rear-end sag when loaded, the airbags will restore proper clearance and prevent tyre contact with guards under compression. If you want to fit larger diameter or wider tyres, you'll need a proper suspension lift kit with raised springs and extended shock absorbers. Visit our lift kits category to explore options that provide genuine ground clearance increase and tyre clearance for your Landcruiser 70 Series.
Airbag Man provides comprehensive manufacturer warranty coverage on all components in this kit, reflecting their confidence in product quality and durability. Specific warranty terms and conditions are detailed in the product packaging and available on the Airbag Man website. The warranty typically covers manufacturing defects and material failures under normal use conditions. For full warranty details, registration requirements, and any exclusions, please refer to the included documentation or contact us directly. Airbag Man has been manufacturing air suspension systems in Australia for over 25 years with an excellent reputation for standing behind their products.
Yes, this Airbag Man kit is designed for all driving conditions — daily commuting, highway cruising, off-road touring and everything in between. When running unladen at low air pressure (5-10 PSI), you'll maintain near-factory ride comfort for daily driving. The airbags only become active and firm when you increase pressure to support loads, so you're not compromising everyday ride quality. Many Landcruiser owners run these systems for years with minimal maintenance, simply adjusting air pressure as needed when loading up for weekend trips or towing the caravan. The system is completely reversible and doesn't affect factory suspension components when installed correctly.
Game changer for our family camping trips
Fitted these airbag helpers to our 79 Series before our last trip to the High Country and the difference was incredible. With the camper trailer, kids' bikes, and all the camping gear loaded up, the rear end used to sag terribly but now it sits level and handles beautifully. The ride quality has improved so much that my wife actually commented on how much smoother it feels over corrugations. Well worth every dollar for anyone doing regular touring with a loaded rig.(5)
