One of the greatest advantages of air suspension helpers is the ability to adjust pressure based on your current load. When running unladen or with minimal cargo, reduce pressure to 5-20 PSI to maintain factory ride quality and comfort. For medium loads such as camping gear, tools, or part-loaded trays, inflate to 30-50 PSI. When towing caravans, camper trailers, or carrying maximum payload, increase pressure to 60-100 PSI for optimal levelling and load support. Always inflate both airbags equally and check pressure before each trip to ensure balanced performance and safe handling characteristics.
The Airbag Man RR4522 kit is designed for bolt-on installation and can be fitted by experienced DIY enthusiasts with basic hand tools, a jack, and axle stands. Average installation time is approximately 120 minutes. The kit includes comprehensive step-by-step instructions accessible via QR code on the packaging, featuring diagrams, torque specifications, and helpful tips. While airbag helpers do not typically require wheel alignment (as they don't alter suspension geometry), it's recommended to have your vehicle inspected by a qualified technician after installation to verify correct fitment and operation. For vehicles also receiving lift kits or other suspension modifications at the same time, professional installation and alignment are strongly advised.

This Airbag Man RR4522 kit is specifically designed to fit Toyota Landcruiser 60 Series models built between November 1980 and December 1991, including BJ60, FJ60, FJ62, HJ60, and HJ61 variants. However, it is only compatible with vehicles without factory differential lock fitted, as the diff lock hardware occupies space required for airbag mounting. If your 60 Series has a factory diff lock, you'll need a different airbag configuration — contact us to confirm the correct kit for your specific vehicle. Always verify your build date and factory options before ordering to ensure perfect fitment.
Airbag helper kits don't increase your vehicle's legal GVM (Gross Vehicle Mass) or payload rating, but they do allow you to safely carry existing rated loads without rear sag, reduced handling, or premature suspension wear. The RR4522 airbags can support significant weight when inflated to maximum pressure (up to 100 PSI per bag), effectively sharing the load with your factory leaf springs and restoring proper ride height. This means you can tow caravans, load camping gear, or carry work equipment up to your vehicle's rated capacity while maintaining safe handling, correct headlight aim, and balanced weight distribution. Always stay within your vehicle's factory GVM and axle load limits regardless of airbag pressure.
The RR4522 kit includes everything you need for a complete installation: two heavy-duty airbags (left and right), custom mounting brackets and all fastening hardware, nylon air lines with compression fittings, dual in-guard inflation valves for easy access, and comprehensive step-by-step installation instructions with QR code access to digital guides. The only item not included is an on-board air compressor, which is an optional accessory if you want to adjust pressure on the go without a service station. All components are designed to work together as a complete system, eliminating the need to source parts separately and ensuring compatibility and performance.
Absolutely — this is one of the most popular applications for air suspension helpers on the 60 Series Landcruiser. When towing heavy caravans or camper trailers, the towball weight can cause significant rear sag, leading to poor handling, reduced braking performance, and dangerous headlight aim. The Airbag Man RR4522 system allows you to dial in the exact air pressure needed to level your vehicle under tow, restoring safe geometry and balanced weight distribution. You can adjust pressure trip-by-trip depending on trailer weight, making it incredibly versatile for touring with different loads or switching between towing and everyday driving.
No, the Airbag Man air helper kit is designed to work with your factory suspension components including leaf springs, shocks, and chassis mounts. It's a supplementary system that assists your existing suspension rather than replacing it. However, if you're planning a comprehensive suspension upgrade — such as fitting a lift kit, heavy-duty shocks, or upgraded springs — it's a good idea to address all components together for optimal performance. Many 60 Series owners also upgrade to heavy-duty shock absorbers or add steering dampers when building a tourer or work vehicle, and our team can help you plan a complete suspension solution tailored to your needs and budget.
Generally, no — airbag helper kits are bolt-on accessories that don't alter suspension geometry or steering angles, so wheel alignment is not typically required after installation. However, it's always good practice to have your vehicle inspected by a qualified technician after any suspension work to verify correct fitment, check for interference, and ensure safe operation. If you're installing this kit as part of a broader suspension upgrade (such as a lift kit or new leaf springs), then a full wheel alignment will definitely be necessary. When in doubt, a quick alignment check provides peace of mind and can help identify any pre-existing wear or adjustment issues.
The RR4522 kit includes in-guard mounted inflation valves that are easily accessible without crawling under the vehicle, allowing you to adjust air pressure quickly using any standard tyre pump, service station air hose, or portable compressor. For ultimate convenience, many 60 Series owners add an on-board air compressor system, which allows you to fine-tune pressure on remote tracks or adjust for changing loads without needing external air sources. Whether you're deflating for unladen comfort or inflating for a heavy tow, pressure adjustment takes just minutes. Always inflate both airbags equally to maintain balanced load distribution and safe handling.
Airbag helper kits are designed for load support and levelling, not for lift height — they don't raise your vehicle's static ride height like a suspension lift kit does. While inflating airbags under load will restore factory ride height (preventing sag), they won't provide the clearance needed for significantly larger tyres. If your goal is to fit bigger tyres and increase ground clearance, you'll need a dedicated suspension lift kit with raised springs and extended shocks. However, airbags are an excellent complement to a lift kit, providing adjustable load support once you've gained the ride height and clearance you need for larger rubber and off-road adventures.
Airbag Man products are backed by a comprehensive manufacturer's warranty covering defects in materials and workmanship, giving you confidence in the quality and durability of your investment. Specific warranty terms and duration can vary, so we recommend reviewing the warranty documentation included with your kit or contacting our team for full details. Airbag Man has over 25 years of proven reliability in the Australian market, with airbags designed to withstand harsh outback conditions, constant pressure cycling, and exposure to dust, mud, and moisture. Routine inspection and maintenance (checking for leaks, inspecting mounting hardware, and ensuring correct inflation) will help ensure long service life and reliable performance.
One of the best features of air suspension helpers is their versatility — you can run low pressure (or even deflate completely) when driving unladen for a comfortable, factory-like ride, then inflate to higher pressure when carrying heavy loads or towing. This makes the RR4522 kit perfect for daily driving, weekend adventures, and heavy-duty touring alike. Many 60 Series owners keep pressure low during the week for commuting and errands, then pump up before heading off on camping trips or towing the caravan. The ability to adjust on demand means you're never compromising comfort for capability or vice versa — you get the best of both worlds in one simple, reliable system.
Sorted the sagging rear end perfectly
Had the old 60 sitting like a low rider with all my tools and gear in the back every day. These airbag helper springs have made a massive difference - not only sits level now but the ride quality is actually better than stock when loaded up. Installation was pretty straightforward too, had them on in an arvo. Well worth the money for anyone running a tradie setup.(5)
Perfect for Our Loaded Family Camping Trips
Fitted these air suspension helpers to our 60 Series before our last trip to the High Country and the difference with a full load of camping gear and the family on board was night and day. The rear end no longer sags when we're loaded up, and the ride quality on corrugated tracks has improved significantly. Installation was straightforward enough for a home mechanic, and being able to adjust the pressure for different loads is brilliant.(5)
