The Airbag Man RR4522 air helper kit is built for Toyota LandCruiser 60 Series (1980-1990) leaf spring rear ends, working alongside your factory leaf springs rather than replacing them. Air pressure is adjustable to match your load — run them soft for an unladen commute and pump them up when the van, camper or tray is loaded, correcting rear sag and keeping the tow ball height level. The kit bolts to existing leaf spring mounting points with no drilling and no permanent ride-height change when deflated. Backed by Airbag Man's local engineering support and dispatched from Australian stock, with fitment guidance from our team if you're unsure.
Airbag Man helper kits use heavy-duty rubber bellows that mount between the chassis and the leaf pack – add air when the load goes on to bring the vehicle back level, then let it out and the standard springs carry on exactly as before. Because each side inflates independently, you can also correct for an off-centre load like a slide-on or water tank.
They shine when the load keeps changing – a van on the towball some weekends, a loaded tray on others. Worth being clear about what they don't do: helper airbags don't increase your GVM or payload; they manage ride height and stability within the vehicle's existing ratings. If the vehicle is always loaded, upgraded springs (with airbags for the variation on top) is the better setup.

This helper kit works with your existing leaf spring rate rather than replacing it, so the main decision is how much constant accessory load you're carrying day to day. Heavier rear-mounted accessories such as dual battery trays, water tanks, drawer systems, bullbars balanced with a rear canopy, or a permanently hitched caravan or camper all add constant weight that a helper kit is designed to offset. If your rear leaf springs are already heavily upgraded, talk to our team about whether a helper kit or a full leaf spring upgrade suits your setup better.
Fitting is a bolt-on job at the leaf spring mounting points and is suited to an experienced DIY installer with basic hand tools, or your regular workshop. A wheel alignment isn't mandatory purely for this kit since it doesn't change static ride height, but it's worth checking alignment if you've recently fitted other suspension components. Run the air bags in for the first 500km at a moderate pressure before loading up fully, and check all fittings and air lines for chafing after the first few trips. These vehicles use solid axles on leaf springs, with no control arms or struts to upgrade; caster at lift height is corrected with caster wedges between the axle and leaf pack, and extended shackles or brake lines may be needed depending on the kit.
Airbag Man has developed air suspension helper kits in Australia for over 25 years, with kits engineered around specific leaf spring and coil spring platforms rather than one-size-fits-all designs. Each kit comes with a manufacturer warranty and is dispatched from Australian stock, backed by our team's fitment support if you have questions before you buy. Tradespeople, tourers and caravan owners running the 60 Series rely on this setup to manage variable payloads without a full spring pack replacement — view the full Airbag Man range for other applications.
This kit suits 60 Series owners who regularly carry a variable load — tradespeople with tool and equipment weight in the tray, tourers running dual battery and water setups, and caravan or camper trailer owners who need to correct tow ball sag. If you're carrying weight most of the time rather than occasionally, it's worth comparing this helper kit against a full airbag suspension setup with our team.
In stock in Australia and ready for fast dispatch, with fitment support from our team if you have questions about your 60 Series setup. Browse our full lift kit range if you're also planning a height change alongside load support.

The RR4522 is designed specifically for the Toyota LandCruiser 60 Series leaf spring rear end, covering the 1980-1990 model range across the 2H, 12H-T and 2F engine variants. It mounts to the factory leaf spring perch and mounting points, so no drilling is required on a standard rear end. If your 60 Series has already had aftermarket leaf springs or a lift kit fitted, contact our team to confirm bracket clearance before ordering.
This is a helper kit, not a lift kit, so it doesn't add a fixed ride-height increase when the air bags are deflated. What it does is let you add air pressure on demand to correct rear sag once you've loaded the vehicle, restoring level ride height under a caravan, camper or tray load. Unladen, the vehicle sits at its normal factory height on the leaf springs. If you want a permanent height increase as well, that's a separate leaf spring or lift kit conversation with our team.
The RR4522 includes two Airbag Man rubber air spring assemblies, vehicle-specific mounting brackets, braided air lines with quick-connect fittings, a single-point inflation valve, all required mounting hardware and fitting instructions. An onboard air compressor and gauge kit are not included and can be added separately if you want to inflate the bags without a hand pump or workshop compressor. Replacement leaf springs are also not part of this kit, since it's designed to work with your factory leaf springs.
Yes, this is one of the main reasons 60 Series owners fit an air helper kit — it lets you firm up the rear end to counter tow ball weight and keep the vehicle level while towing a caravan or trailer. Once you unhitch, you can deflate the air bags back down for a softer unladen ride. It's a practical option if your towing load varies trip to trip rather than being constant.
This vehicle runs solid axles on leaf springs, so there are no upper or lower control arms or struts like an IFS vehicle. When lifting with taller leaf springs, caster change is corrected with caster wedges fitted between the front axle and the leaf packs, and longer shackles or extended brake lines may be needed depending on lift height. Our team can advise what your build needs.
A wheel alignment isn't mandatory purely for fitting this air helper kit, because it doesn't change your static, unladen ride height or suspension geometry. It's still good practice to check your alignment if you've recently fitted other suspension components or if you've noticed uneven tyre wear. If in doubt, ask your fitting workshop to check alignment while the vehicle is up on the hoist.
This kit is a helper system that adds adjustable support to your existing leaf springs rather than replacing the spring pack, so there isn't a spring rate choice within the RR4522 itself. Adjustment happens through air pressure — softer for unladen driving, firmer once loaded. If your factory leaf springs need a heavier rate to suit a permanent constant load, that's a separate leaf spring upgrade our team can advise on.
Because this is a helper kit and not a permanent lift, it won't create the extra wheel-arch clearance that a taller leaf spring or lift kit would provide for larger tyres. Tyre clearance on your 60 Series will be governed by whatever ride height and spring setup you already have. If you're chasing bigger tyres as well as load support, talk to our team about combining this kit with a leaf spring upgrade.
The RR4522 is covered by Airbag Man's manufacturer warranty, reflecting the brand's build quality on the air spring assemblies and fittings. Exact warranty terms are confirmed at the time of purchase — contact our team via the contact page if you'd like the specific warranty period in writing before you order. We also provide fitment support if you run into questions during installation.
Yes, that's part of the point of an air helper kit — you run the air bags soft or fully deflated for everyday unladen driving so the factory leaf spring ride quality isn't compromised, then pressure up only when you're loaded or towing. This on-demand adjustability is what separates a helper kit from a fixed heavy-duty spring, which stays stiff all the time. It suits 60 Series owners who use the vehicle both for daily driving and periodic heavy loads.
