LDV D90 Load Assist Kit: Ride Height & Towing (2026)
The LDV D90 is a solid tourer and tow vehicle, but load it up with camping gear or hitch a decent trailer and the rear end sags fast. This guide covers what an LDV D90 load assist kit actually needs to do, what to check before buying one, and where Boss Air Suspension's current product range fits in for 2026.
- No dedicated ldv d90 load assist kit is listed on Boss Air Suspension's site as of 2026 — confirm fitment before buying any airbag kit for this vehicle.
- Rear suspension type (leaf spring vs coil) must be confirmed before any airbag is fitted — Skip any kit that doesn't name your D90 variant specifically.
- A full onboard air setup matters as much as the airbag itself — Buy the Boss Auto Pressure Controller Kit with PX06 Compressor if you're building a complete system.
- In-cab digital pressure adjustment is worth having on a tow rig that switches between empty and loaded runs — Consider the Digital Airbag Inflation Kit PX01.
Why this matters
A D90 running low at the back under load isn't just uncomfortable. It changes headlight aim, reduces steering feedback and puts more strain on the rear shocks and bump stops.
Load assist airbags work with the factory suspension to hold ride height steady when you're towing a caravan, carrying camping gear or running a canopy setup. They don't add legal payload or GVM capacity — they help the existing suspension do its job properly under the load it's already rated for.
Before fitting anything to a D90, the first step is confirming what's actually engineered and tested for this vehicle. How to choose the right load assist airbag kit covers the fitment checks that matter regardless of make or model, and it's worth reading before you spend money on any listing that claims to be universal.
Who this is for
This guide is for LDV D90 owners who tow a caravan, camper trailer or boat, or who regularly carry heavy gear for touring and 4WD trips. If your D90 sits noticeably lower at the back with a load on, sways more than it should while towing, or you've noticed the headlights pointing higher than normal, this is the situation a load assist kit is built to address.
What to look for in a load assist kit for LDV D90
Confirmed vehicle-specific fitment
A kit listed for a different ute or wagon platform will not bolt onto a D90 without modification, and modified brackets are where leaks and premature airbag wear start. As of 2026, Boss Air Suspension does not have a dedicated LDV D90 listing published — if you see a kit online claiming to fit most 4WDs including the D90, treat that as unconfirmed until you've checked with the supplier directly.
Matching rear suspension type
Airbag kits are engineered around a specific rear suspension design — leaf spring, coil spring or multi-link — because the mounting points and bag geometry differ between each. Fitting a kit designed for the wrong suspension type is the single most common cause of a poor install, regardless of vehicle.
Adjustable air pressure range
A D90 running empty around town and then loaded for a trip needs a wide, easily adjustable pressure range rather than a fixed setting. Airbags that can be dropped low for an unladen ride and pumped up for towing give you comfort both ways, instead of forcing a compromise.
Full onboard air control, not just the airbags
An airbag on its own is only half the system. You still need a way to add and release air — either a hand pump, a 12V compressor with a gauge, or a full pressure controller with an onboard tank. For a vehicle that tows regularly, a compressor-based setup saves you stopping to hand-pump every time the load changes.
Warranty and local support
Because the D90 doesn't yet have a confirmed listing, anything you buy for it in the interim should come with clear installation support and a warranty that covers the components, not just the airbag rubber. Boss Air Suspension backs its confirmed vehicle-specific kits with a five-year warranty — a useful benchmark to compare any interim solution against.
Top picks for a D90 onboard air setup
Until a confirmed LDV D90-specific load assist kit is published, the practical move is to plan the onboard air side of the system — the parts that don't depend on vehicle-specific bracket geometry. These are genuine Boss Air Suspension products worth knowing about now.
The control centre — Boss Auto Pressure Controller Kit with PX06 Compressor
This kit bundles a PX06 12V compressor, a 9-litre aluminium tank, fittings, a water trap and a Nitto coupling into one onboard air package priced at A$1,380. It's built for drivers who want to run and adjust load assist airbags without leaving the cab, and the tank doubles as a source for tyre inflation on tour. Buy — it's the right foundation for a D90 onboard air system once fitment is confirmed, and it's not vehicle-specific so it won't be wasted if you fit a different airbag brand later.
In-cab control — Digital Airbag Inflation Kit PX01 (3-Button)
The PX01 gives you a digital, in-cab readout and three-button control to add or dump air on the move, which matters if your D90 switches between an empty commute and a loaded tow run in the same week. It removes the guesswork of eyeballing a gauge under the tray. Consider — worthwhile if you change loads often; skip it if your D90 mostly runs at one fixed load and you're happy setting pressure once.
The finishing kit — Airbag Fitting Kit
Whatever airbag ends up confirmed for the D90, you'll need the lines, push-connect fittings and hardware to plumb it into a compressor or hand pump. Boss Air Suspension sells this separately so you're not paying for a bundle you don't need. Buy — cheap insurance against a half-finished install once a D90-specific kit is available.
The core component — Boss Airbag 2500
The Boss Airbag 2500 is the bare airbag used across a number of Boss Extreme Series applications. It is not a confirmed fitment for the LDV D90 on its own — brackets and mounting geometry are what make an airbag vehicle-specific, not the bag itself. Confirm — don't buy a bare airbag for a D90 install without first getting written confirmation from Boss Air Suspension that the bracket kit exists or can be engineered for this application.
“If a listing doesn't name your vehicle by model and drivetrain, treat it as unconfirmed and check before you buy.”
What to avoid
- Universal-fit airbag kits with no vehicle list. They're often built for leaf-spring utes and won't sit right on a coil or multi-link rear end without custom brackets — and a bad bracket is where leaks start.
- Adapting a kit built for a different ute. A Ranger, Hilux or Amarok kit will not bolt onto a D90's mounting points even if the airbag itself looks similar in photos.
- Running maximum pressure to compensate for an unconfirmed fit. Overinflating a poorly matched airbag to force it to hold ride height accelerates wear and can split the bladder well before it should fail.

FAQ
Does Boss Air Suspension make a load assist kit for the LDV D90?
As of 2026, no dedicated LDV D90 load assist kit is listed on the Boss Air Suspension site. Contact Boss Air Suspension directly to check whether a vehicle-specific bracket kit exists or can be confirmed for your D90 variant before buying any airbag kit.
Will a load assist kit increase my D90's towing capacity or GVM?
No. A load assist kit works with the existing rear suspension to help maintain ride height and stability under a load the vehicle is already rated to carry — it does not increase legal payload, GVM or towing capacity unless it's part of an approved GVM upgrade.
What air pressure should I run in load assist airbags?
Air pressure depends on the specific airbag, the load and the vehicle, and it should be set against the manufacturer's documented range for that kit once fitment is confirmed. Running too high a pressure for an unconfirmed or mismatched setup increases the risk of premature wear.
Can I use a load assist kit built for another ute on my LDV D90?
No, cross-fitting a kit built for a different vehicle is not recommended because mounting brackets and bag geometry are engineered per vehicle. Using the wrong kit risks poor ride height correction and premature airbag failure.
Do I need a compressor to run load assist airbags?
A hand pump can work for occasional adjustment, but a 12V compressor with a gauge or a full pressure controller is more practical for a vehicle that tows regularly. The Boss Auto Pressure Controller Kit with PX06 Compressor bundles the compressor, tank and fittings into one onboard system.
How long does a load assist kit last?
Confirmed vehicle-specific Boss Air Suspension kits are backed by a five-year warranty, which reflects the expected service life under normal towing and touring use. Actual lifespan depends on load frequency, pressure management and installation quality.
Is a load assist kit legal in Australia?
Load assist airbags that work with the existing suspension and don't alter the vehicle's rated payload or GVM are a common and accepted modification across Australia. Always check current state-based modification rules if you're unsure, especially where a GVM upgrade is also involved.
One last thing
The biggest mistake with any unconfirmed fitment isn't buying the wrong airbag — it's buying the onboard air components twice because the first setup was built around guesswork. Sort the compressor, tank and fitting kit first, since none of that changes once a confirmed LDV D90 load assist kit is published, and you'll only need to source the vehicle-specific bracket kit when it's available.
