This Airbag Man helper kit bolts between the chassis and rear leaf spring pack on your Toyota LandCruiser 75 Series (FZJ75 petrol, HZJ75 diesel, 1990-1999) and gives you infinitely adjustable air pressure from 5 to 100 PSI. Unlike a fixed spring upgrade, you dial in exactly the support you need — soft at 5-20 PSI unladen, firm at 40-100 PSI when towing or loaded. It works alongside your existing leaf springs with no cutting or drilling required. In stock now with Airbag Man's manufacturer warranty and fitment guidance from our Australian team.

This is a helper kit, not a fixed spring rate upgrade, so the airbag pressure itself is your adjustment tool rather than a spring rate choice. Run 5-20 PSI for an empty tray or unladen touring, and step up to 40-100 PSI as you add a dual spare, rear bar, jerry can holder, toolbox, fridge slide, rooftop tent, or caravan tow ball weight. If your constant load is heavy year-round, ask us about pairing this kit with a heavier-rated leaf spring instead of running high air pressure permanently.
Fitment is straightforward for an experienced DIYer with basic hand tools and jack stands, though a qualified mechanic install is recommended if you're not confident working under the rear axle. No suspension geometry changes, so a wheel alignment is not mandatory purely from fitting this kit — but always check ride height and tyre clearance once loaded to your typical towing weight. Air line routing needs to clear the exhaust, moving suspension components, and sharp chassis edges. For vehicles running heavier rear accessories, it's worth reviewing your shock absorbers at the same time, since they carry the extra load cycling alongside the airbags.
Airbag Man has specialised in Australian air suspension for over 25 years, supplying tradies, tourers, and caravan owners running heavy rear loads on 4WDs like the 75 Series. Kits are backed by a manufacturer's warranty and supported by our local fitment advice, so you're not guessing on compatibility. Have a look at the full Airbag Man range if you're after airbags, shocks, or springs for other vehicles in the fleet.
This kit suits 75 Series owners who tow caravans, camper trailers, or horse floats and notice rear sag once hitched up. It's also a solid fit for tradies carrying tools daily and tourers running rooftop tents, dual spares, or long-range fuel tanks. If your load varies trip to trip, airbag suspension gives you on-demand adjustment that a fixed spring rate can't match.

Yes, this Airbag Man kit (SKU RR4501) is built specifically for the 75 Series MK2 leaf spring models built 1990-1999, covering both the FZJ75 petrol and HZJ75 diesel. It mounts to the factory rear leaf spring perch and chassis rail using the supplied brackets and U-bolts. If your 75 Series has had a rear spring or axle modification, check with our team first via the parts finder before ordering.
This is a load-leveling helper kit, not a lift kit, so it doesn't raise your unladen ride height. At minimum pressure (around 5 PSI) the airbags sit passive and your factory ride height is unchanged. Once loaded or towing, increasing pressure toward 100 PSI brings the rear back up to level, correcting sag rather than adding permanent lift. If you want a genuine lift, look at our leaf spring or lift kit options instead.
You get two Airbag Man rubber air springs, chassis and axle mounting brackets, U-bolts and fastening hardware, nylon air line, an inflation valve, and detailed fitting instructions. Everything needed to mount the kit between the chassis and rear leaf pack is supplied. Shock absorbers and leaf springs are not included, as this kit works alongside your existing setup.
Yes, this is one of the main reasons 75 Series owners fit it. Running higher air pressure (40-100 PSI depending on tow ball weight) reduces rear sag, body roll and sway when towing a caravan, camper trailer or horse float. It's a helper system though, so your factory leaf springs and tow rating still apply — this kit supports the load, it doesn't increase your GVM or towing capacity.
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.
Not mandatory from this kit alone, since it doesn't change ride height or suspension geometry when unloaded. It's still good practice to check ride height and tyre clearance once you've loaded the vehicle to your typical towing or work weight. If you fit this alongside a leaf spring or lift kit change, get an alignment done as part of that install.
This kit doesn't come in different spring rates — it's an adjustable air pressure system, so you set the support level yourself between 5 and 100 PSI. That's actually the advantage over a fixed-rate spring: you can run soft for unladen comfort and firm up only when loaded or towing. If you'd prefer a fixed heavier-rated leaf spring instead, we stock options in our leaf spring range.
Since this kit doesn't raise unladen ride height, it won't create extra tyre clearance the way a leaf spring or lift kit upgrade would. Tyre clearance stays as per your current suspension setup. If bigger tyres are the goal, talk to us about pairing this airbag kit with a leaf spring upgrade for genuine additional height.
This kit is backed by Airbag Man's manufacturer warranty covering the air springs and hardware against manufacturing defects. Contact our team for the exact current warranty term and claim process, as we can confirm this against your specific order. We also provide fitment support if you have questions before or after installation.
Yes. Run the airbags at 5-20 PSI for daily unladen driving and the rear ride quality stays close to factory feel. When you load up for work or hitch up the van, wind the pressure up to suit — then drop it back down for the commute home. That flexibility is the main reason tradies and grey nomads run this setup as a daily driver solution.
