Start with 20-30 PSI for moderate loads (roof racks, bull bars, rear drawers), increase to 40-60 PSI for caravan or camper trailer towing (2000-3000kg), and run 70-100 PSI for maximum payload or off-road touring with full water tanks and recovery gear. Always inflate equally side-to-side unless compensating for uneven loads. Common rear accessories that benefit from airbag support include rooftop tents, dual spare wheel carriers, long-range fuel tanks, rear drawer systems, portable fridges, water tank systems, awnings, and heavy-duty rear bars.
Professional installation is recommended due to drilling and cutting requirements for airbag and bracket fitment — allow approximately 120 minutes for experienced mechanics. Wheel alignment is not typically required unless you're combining this kit with suspension lift kits or replacing springs simultaneously. After installation, cycle airbags through full inflation range (5-100 PSI) three times to seat components, then adjust pressure to match your current load. For optimal performance on long-distance touring, pair this kit with quality steering dampers to reduce body roll and improve towing stability on corrugated outback roads.

Yes, the Airbag Man CR5049 is specifically engineered to fit Toyota Landcruiser 80 Series models (FJ80, FZJ80, HDJ80, HZJ80) from August 1991 to 1998, and Landcruiser 300 Series from 2021 to 2024. Both petrol and diesel variants are compatible, including models equipped with Toyota's Electronic Kinetic Dynamic Suspension System (E-KDSS). The kit is designed exclusively for coil spring rear suspension — if you're unsure about your specific model or have aftermarket suspension modifications, contact our team for confirmation before ordering.
The Airbag Man CR5049 provides adjustable load support from minimal assistance at 5 PSI up to maximum support at 100 PSI, with a recommended maximum load capacity of approximately 2000kg when properly inflated. The variable pressure range allows you to fine-tune support based on your exact load — whether you're carrying light camping gear, towing a 2500kg caravan, or loaded for extended outback touring. Inflate to higher pressures for heavy loads and towing, or run lower pressures for everyday driving to maintain factory ride comfort and suspension articulation.
This complete installation kit includes 2 heavy-duty rear airbags designed for coil spring applications, vehicle-specific laser-cut mounting brackets, stainless steel hardware (bolts, washers, lock nuts), premium nylon air line tubing, quick-release air fittings, and tyre-style Schrader inflation valves. You'll also receive comprehensive step-by-step fitting instructions accessible via QR code and a detailed operation manual. The kit contains everything needed for installation except an air compressor for inflation — you can use your existing onboard compressor, portable unit, or service station air.
Absolutely — this Airbag Man kit is specifically designed for towing applications and is one of the most popular upgrades for Landcruiser owners who regularly tow caravans, camper trailers, or boat trailers. The airbags eliminate rear squat, maintain level ride height under towball weight, improve headlight alignment, and enhance stability and control when towing on highways or corrugated outback tracks. Adjust air pressure to match your towing load for optimal weight distribution and safer braking performance. Many Australian tourers run these airbags continuously when towing across the country.
No, this airbag helper kit works with your factory control arms and does not require any control arm upgrades for installation or operation. Airbag Man kits are designed as load-levelling assisters that support your existing coil springs — they don't alter suspension geometry or ride height in the same way a lift kit would. However, if you're planning a complete suspension overhaul combining lift, heavy-duty springs, and long-travel shocks, upgraded control arms may be beneficial for improved handling and articulation. Contact our team if you're planning multiple suspension modifications simultaneously.
No, wheel alignment is not typically required after installing this airbag helper kit, as the system does not alter your Landcruiser's suspension geometry or ride height when deflated. The airbags function as load-support assisters that compress to minimal profile when not inflated, allowing your factory suspension to operate normally. However, if you're installing this kit at the same time as lift kits, new springs, or replacing steering and suspension components, then professional wheel alignment will be mandatory. Always have alignment checked if you notice uneven tyre wear or steering pull after any suspension work.
The standard CR5049 kit includes tyre-style Schrader valves mounted in an accessible location, allowing you to inflate or deflate the airbags using any air compressor when stationary. For on-the-fly pressure adjustment while driving, you can upgrade to an optional in-cab air control system (sold separately) that features dash-mounted gauges and inflation controls. This allows you to adjust airbag pressure from the driver's seat — ideal for quickly adapting to changing loads, road conditions, or when transitioning between highway towing and off-road touring. Many long-distance tourers invest in wireless or manual in-cab systems for maximum convenience.
This airbag kit does not increase ride height or suspension lift when deflated — it's designed purely as a load-levelling system that supports your existing coil springs under load. Therefore, it will not provide additional tyre clearance for larger tyres on its own. If you're looking to fit larger all-terrain or mud-terrain tyres on your Landcruiser 80 or 300 Series, you'll need to install a dedicated suspension lift kit to gain the necessary clearance in the wheel arches. Airbag kits can be installed alongside lift kits to provide both increased ride height and adjustable load support for the ultimate touring setup.
Airbag Man backs this CR5049 kit with a comprehensive manufacturer's warranty covering defects in materials and workmanship — specific warranty terms and duration are detailed in the included documentation and on the Airbag Man website. As an authorised Australian retailer, 4WD Suspension provides full warranty support and can assist with any claims or technical issues. Airbag Man has been manufacturing air suspension systems in Australia for over 25 years and stands behind their products with proven reliability across hundreds of thousands of kilometres of outback touring, daily towing, and commercial use.
Yes, this airbag kit is perfect for daily driving because when deflated (5-10 PSI or empty), the airbags compress to minimal profile and allow your factory coil springs to operate exactly as Toyota designed them — maintaining original ride comfort, handling, and off-road articulation. Inflate the airbags only when you're carrying heavy loads, towing, or touring with expedition gear, then deflate them for normal commuting and unloaded driving. This versatility makes airbag systems ideal for Landcruiser owners who switch between weekday family duties and weekend adventures, or tradespeople who alternate between loaded work days and empty return trips.
Perfect for Our Loaded Family Camping Trips
Finally sorted the rear sag on our 80 Series when we're loaded up with the camper trailer, kids, and all our gear for weekend trips down south. The Airbag Man helper kit made a massive difference to the ride quality, especially on corrugated tracks. Installation was straightforward enough to do in the driveway, and the adjustability means I can fine-tune it depending on the load we're carrying.(5)
Perfect for Our Loaded Family Camping Trips
Fitted these airbag helpers to our 80 Series before our last Cape York trip and the difference was night and day. With the camper trailer, roof top tent, and all the family gear loaded up, the rear end used to sag terribly, but now it sits level and handles beautifully even on corrugations. Installation was straightforward enough for a weekend in the shed, and being able to adjust the pressure for different loads is a game changer.(5)
Best upgrade I've done to the Cruiser
Had these airbags fitted to my 80 Series about six months ago and they've been absolute ripper for hauling tools and materials around sites. The difference when loaded up is night and day - no more sagging rear end when I've got a tonne of gear in the back. Installation was pretty straightforward too, took me and a mate a few hours in the shed with a couple of beers.(5)
Game changer for our loaded up Cruiser
Fitted these airbag helpers to our 300 Series before our last trip down the coast and the difference with a full load of camping gear and the kids was incredible. The rear end used to sag pretty badly with everything packed in, but now it sits level and handles so much better on the highway and dirt roads. Installation was straightforward enough for a weekend job, and the ride quality is noticeably smoother even when we're running them at lower pressure for daily driving.(5)
