Airbag Suspension for LandCruiser: Best Kits 2026
Airbag suspension for a Toyota LandCruiser keeps the rear end level when you're towing a van or loaded up for touring, and the right kit depends entirely on whether your LandCruiser runs leaf springs or coils out back.
- Airbag suspension for a LandCruiser reduces rear-end sag under load — it doesn't increase GVM or towing capacity.
- Load Assist Kit for leaf-spring LandCruisers (70/79/80/100 Series) covers standard height through to 4 inch lift — Buy for tourers and tow rigs.
- Coil Assist Kit for 300 Series and Prado 250 suits coil-sprung rears up to 2 inch lift — Buy for newer wagons.
- Skip kits built for other utes or the wrong spring type — bracket mismatch is the most common fitment mistake in 2026.
Why this matters
A loaded LandCruiser towing a caravan or carrying camping gear in the tray sits nose-up and tail-down. That sag reduces headlight reach at night, throws off handling, and puts more strain on the rear suspension than it's designed to carry alone.
A Load Assist Kit for Toyota LandCruiser leaf spring rear at standard height works with your existing suspension rather than replacing it. Air pressure adjusts to suit the load on any given trip, so the same kit handles an empty run to the shops and a fully loaded tow to the coast.
Airbag suspension does not increase your LandCruiser's legal GVM or towing capacity. What it does is help the vehicle sit level and stable within its existing rating, which matters more than most owners realise once a van or camper trailer is hooked up in 2026 conditions.
Who airbag suspension for a LandCruiser suits
This guide is for LandCruiser owners towing caravans, camper trailers or boats, and for those carrying canopy, tray or drawer system weight on touring trips. It also applies to owners running a rear suspension lift who've noticed the vehicle still sags when loaded, and to fleet or touring operators who need consistent ride height trip after trip.
If your LandCruiser rarely carries more than light gear and never tows, a load assist kit is unlikely to earn its keep. This is a tool for vehicles that regularly work under load, not a general ride-quality upgrade.
What to look for in airbag suspension for a LandCruiser
Correct spring type — leaf or coil
Leaf-spring LandCruisers (70 Series, 79 Series, and leaf-sprung 80/100 Series) need a load assist kit built around leaf spring mounting points. Coil-sprung models like the 300 Series and Prado 250 need a coil assist kit designed for that rear end. The two are not interchangeable, and getting this wrong means brackets that don't line up.
Lift height compatibility
If your LandCruiser has an aftermarket suspension lift, the airbag kit needs to be rated for that lift height. Boss Air Suspension's leaf spring range covers standard height through 2, 3 and 4 inch lift in 2026, and fitting the wrong height kit changes bellows travel and can affect how the airbag sits under load.
Adjustable air pressure range
A good load assist kit lets you wind pressure up for a heavy tow and back down for an unladen run. This matters for LandCruiser owners who alternate between empty daily driving and fully loaded touring trips, since a fixed-pressure setup is either too soft loaded or too hard empty.
Bracket and mounting quality
Brackets carry real load repeatedly over rough touring roads, so fit and material quality matter more than they look like they should on paper. A kit engineered specifically for your LandCruiser's chassis points sits differently to a universal bracket forced into place.
Warranty and local support
A five-year warranty backing the kit tells you the manufacturer expects the bellows and brackets to handle Australian conditions long-term. Local support also matters if you need help identifying the right kit for your exact LandCruiser variant and lift height.
Top picks for LandCruiser owners
The stock-height pick: Load Assist Kit for Toyota LandCruiser leaf spring rear, standard height. Built for 70/79/80/100 Series LandCruisers running factory ride height, this kit comes in at $745 and is the starting point for owners who haven't lifted the rear end. Buy if your LandCruiser sits at standard height and you're towing or carrying loads regularly.
The lifted tourer's pick: Load Assist Kit for Toyota LandCruiser leaf spring rear, 2 inch lift. Matched to a 2 inch rear lift, this kit is priced at $745 and suits touring rigs already carrying a suspension upgrade. Buy for LandCruisers with a 2 inch lift that still sag once loaded for a trip.
The coil-sprung pick: Coil Assist Kit for Toyota LandCruiser 300 Series and Prado 250, up to 2 inch lift. Designed for the coil rear end on newer LandCruiser 300 and Prado 250 wagons, this kit adds adjustable airbag support without touching the factory coil setup. Buy if you're running a 300 Series or Prado 250 with up to a 2 inch lift and towing regularly.
The heavy tourer's pick: Load Assist Kit for leaf spring rear, 4 inch lift, $805. This suits LandCruisers with a substantial rear lift that still need airbag support once a van or heavy canopy load goes on. Consider this one if your rear lift is already at the 4 inch mark and rear sag is still noticeable when hooked up to a caravan.
The middle-ground pick: Load Assist Kit for leaf spring rear, 3 inch lift, $805. Between the 2 and 4 inch options, this fills the gap for LandCruisers with a moderate rear lift. Consider if your lift height sits closer to 3 inches than 2 or 4.
What to avoid
- A kit built for another vehicle. Airbag kits for the Ford Ranger, Hilux or D-Max look similar but use different mounting points — a LandCruiser-specific kit is the only one that bolts up correctly.
- Mismatched spring type. A coil assist kit will not fit a leaf-spring 80 or 100 Series, and a leaf spring kit has no application on a coil-sprung 300 Series or Prado 250.
- Treating airbags as a GVM increase. Load assist airbags help the vehicle sit level under an existing legal load — they don't raise your LandCruiser's GVM or towing capacity, so overloading beyond the compliance plate is still overloading.

FAQ
What's the best airbag suspension for a LandCruiser towing a caravan?
For leaf-spring LandCruisers (70/79/80/100 Series), the Load Assist Kit matched to your current ride height is the right starting point. For coil-sprung 300 Series and Prado 250 models, the Coil Assist Kit up to 2 inch lift covers most towing setups in 2026.
Does airbag suspension increase my LandCruiser's GVM or towing capacity?
No. Load assist and coil assist kits help the vehicle sit level and stable within its existing GVM rating — they don't change the vehicle's legal GVM or towing capacity.
What's the difference between a load assist kit and a coil assist kit?
A load assist kit is built for leaf-spring rear ends and mounts around the leaf pack, while a coil assist kit is built for coil-sprung rear ends like the 300 Series and Prado 250. They use different mounting hardware and aren't interchangeable.
How much does a LandCruiser load assist kit cost in 2026?
Boss Air Suspension's LandCruiser leaf spring kits run from $745 for standard height and 2 inch lift up to $805 for 3 and 4 inch lift options in 2026. Coil assist kits for the 300 Series and Prado 250 start at $745.
Can I fit a LandCruiser airbag kit myself?
The kits are designed as a bolt-on installation with the brackets and air lines included, and many owners fit them at home with basic tools. If you're not confident working under the vehicle, a workshop familiar with air suspension can fit it in a few hours.
Do I still need airbags if my LandCruiser already has a suspension lift?
Yes, if the vehicle still sags once loaded for towing or touring. A suspension lift raises ride height but doesn't add load-carrying support the way an airbag kit does.
How long do Boss Air Suspension LandCruiser kits last?
Kits are backed by a five-year warranty, and bellows are built from double or triple layer material rated for Australian touring and towing conditions.
Is airbag suspension worth it for occasional towing?
If you tow a caravan or trailer even a few times a year, adjustable air pressure means the kit works for both loaded and unloaded driving rather than sitting fixed for one use case.
One last thing
Most sag complaints on a LandCruiser aren't really an airbag problem — they're a pressure problem. Owners who leave airbags maxed out from their last big tow, then drive around empty for weeks, are putting more strain on the bellows than towing does. Adjust pressure to the load each trip, not once and forget it.
